Toilet grinder pump: design variations and installation instructions

Kinds

Conventionally, these devices are divided into two categories:

• household;
• Industrial.

Household appliances are used for pumping wastewater and can be installed not only in country houses, but also in apartments. Industrial - used in apartment buildings and substations that are connected to the sewer.

Household units differ in the place of installation and purpose. They also differ in the type of construction. There are devices that are installed for use by one consumer, and there are pumps used for forced sewage of an entire house.

Pumps for sewerage in the apartment are produced in the following versions:

• For a toilet bowl with a grinder;
• For kitchen without chopper.

Dressing

box, the dimensions of which correspond to the dimensions of the drain barreltoilet

The color of the body of the device is selected to match the color of the toilet bowl. During the drain, the device filled with water, with the help of blades, begins to grind waste water and toilet paper. Larger debris, such as personal care products, cannot be handled.

Such a unit can pump wastewater, the temperature of which is from +35 to + 50 degrees. Many models have additional holes for connecting a shower or bidet.

Therefore, when choosing a unit, water temperature plays an important role. If it is higher than the specified indicators, then the equipment may deteriorate. In some models, a relay is installed that turns off the device after half an hour, after pumping hot water.

In addition to these fecal pumps, there are built-in devices with choppers that are used for hanging toilets. They are distinguished by their compact size, which allows them to be hidden behind a plasterboard partition.

There are models in which the toilet and the pump are combined. In this design, there is no drain tank. It connects directly to the water supply and takes up little space.

kitchen

Models for installation in the kitchen are called sanitary. Their purpose is to pump dirty water. There are no choppers in the design of sanitary pumps, therefore, large fractions should not be contained in the water.

Kitchen sewer pumps have several inputs for connecting several drains from:

• sinks;
• bathroom;
• shower room;
• Washbasin.

When choosing a unit for the kitchen, you need to pay attention to the temperature of the wastewater.The maximum temperature of some models is +90 degrees, which allows you to connect a washing machine and dishwasher to them

Important: kitchen equipment is covered with a layer of grease from the inside, so it is important to take the time to clean them periodically.

Installation. Characteristics

Let's move on to the section: installation. Characteristics.

Consider the process of installing a chopper pump using the example of organizing an additional bathroom in the basement of a country house.

_

Organization - means legal entities under the laws of the Russian Federation (except for banks), including organizations whose main activities are financed from the budget.

To install a grinder pump, you need:

• supply of cold water for the bathroom.
• plug socket;

Discharging wastewater through a PVC pipe of small diameter - 22 - 32 mm, the pumpchopper installed behind a standard toilet with a horizontal outlet. Certain heavy duty pumps use 50 mm pumping pipes. The outlet piping can be made of classic PVC pipes or from polypropylene pipes.

_

Wastewater - water discharged in accordance with the established procedure into water bodies after its use or received from a contaminated area.

Also in the SFA line there are installation kits for the bathroom and a wall-mounted toilet - for example, say, SANIWALL Pro UP. Thanks to the frosted glass and design, the kit is installed directly behind the wall-hung toilet and allows for aesthetic installation. the entire bathroom, this is a mounting rack + pump-chopper + decorative glass, which makes it easy install a conventional or hanging toilet bowl with a washbasin connection. Later, after the sewage has been crushed, the sewer unit pumps out the dirty water coming from the washbasin and toilet bowl. As soon as the pump tank is filled with water, the motor is turned on and the knives work automatically. Removal occurs in the vertical/horizontal direction. It will take 3-4 seconds to grind particles and pump out. Dual flush system (3/6 liters) saves water.

Specifications SFA SANIWALL Pro UP:

• maximum vertical pumping: 5 m;
• power (Watts): 400;
• voltage: 220-240V/50Hz.
• pumping diameter: 22 - 32 mm;
• maximum horizontal pumping: 100 m;
• throughput: > 90 l/min;

Risk — a combination of the frequency (or probability) and consequences of a particular hazardous event. The concept of risk always includes two elements: the frequency with which a dangerous event occurs, and the consequences of this event. (SP 11-107-98)

All units are equipped with a non-return valve, which prevents untimely switching on of the equipment and prevents any risk of water flowing back into the toilet bowl or other plumbing fixtures. Since they perform only mechanical actions (grinding and ejection of wastewater), at the same time no chemicals are used, pump grinders are successfully combined with a septic tank.

<-

When installing the pump, it is important to follow the following rules to prevent noise during operation of the device:

• to prevent movement of the unit, screw the fixing tabs to the floor;
• for the anti-vibration clamps to function properly, install the pump on a level floor surface;
• for better soundproofing, you can also put a sheet of soundproofing material between the grinder pump and the floor surface and/or wall.
• correctly fix the system of outlet pipes in such a way as we can see that the distance between the fasteners does not exceed one meter;
• to reduce vibration, securely attach anti-vibration clamps under the bottom surface of the pump in the places provided for this;
• install the pump in such a way that it does not touch the wall;

rule — a clause describing the actions to be performed. (SNiP 10-01-94)

Soundproofing is ten times the logarithm to the base 10 of the ratio of the sound power incident on the test specimen to the sound power transmitted through that specimen. (GOST 26602.3-99)

materials - a collective term denoting a variety of material elements of production, used mainly as objects of labor - raw materials, basic and auxiliary materials, fuel, energy, purchased products and semi-finished products, overalls, spare parts for repairs, tools and low-value and quickly wearing out items.

Flawless Connecting Procedure

Before starting installation, determine the place where the device will be installed. There are some rules here. First of all, it is strictly forbidden to expose the pump below the floor level. The equipment must be located directly next to the toilet, at a distance of no more than 0.4 m. It is necessary to provide free access to the device so that maintenance and repair work can be carried out without difficulty.

You should once again make sure that the diameters of the sewer pipe and the pump inlet pipe match. If not, an adapter is purchased. In addition, a non-return valve must be installed on the pump outlet. If it does not exist, an extremely unpleasant situation is not ruled out, when sewage from the sewer will pour into the toilet. check valve can be included in the pump package, if not, you need to buy it in addition.

Before installation, carefully read the instructions that come with the device. Ideally, it should be in Russian. The document describes in detail the installation process of the selected model. In addition, all the necessary diagrams and illustrations are always attached to the instructions. Once again check the package, make sure that all the parts and fasteners necessary for installation are present.

Some models of sanitary pumps are equipped with carbon filters that eliminate unpleasant odors. They should be changed regularly, otherwise the device will not be able to function effectively.

After the preparation for installation is completed, you can proceed with the installation procedure. It is carried out as follows. First, we insert supply pipes or connecting elbows into all inlet pipes of the pump. We make sure that the line fits the device at a slope of 3 cm for every running metre. This will allow the drains to move by gravity to the device, which is necessary for its normal operation.

If there are more inputs than required at the moment, we put suitable plugs on the “non-working” holes.Then we install the pump on a pre-selected and prepared place. We find special cast ears for fasteners on the body of the product, insert screws into them and fix the pump to the floor. We proceed to laying the pipeline from the pump to the sewer riser.

Ideally, pipes run straight, turns should be avoided or, if this is not possible, they should be made as gentle as possible. In the presence of joints between pipes, soldered, welded or adhesive joints are made. Their quality must be high so that subsequently there is no leak.

If the pump will have to lift the drains up and it is planned to equip a vertically standing outlet, it should be located at a distance of no more than 0.3 m from the outlet of the device.

Only in this case the device will be able to function normally. The connection of the pipe leaving the toilet bowl with the pump is carried out using a corrugation. In this case, it is imperative to equip it so that the inlet pipe of the pump is located lower than the outlet pipe from the toilet. In addition, it is necessary to provide the necessary slope for the drain pipe so that the drains move by gravity.

The pump with a chopper for the toilet is volatile, therefore it requires an electrical connection. For safety reasons, this should only be done through the RCD.

The next step is the arrangement of ventilation. This procedure is necessary for models without carbon filter, the design of which provides for a special ventilation outlet. The pipe must be brought out above the ridge on the roof of the house. If this seems like too much trouble, you should choose a model with a replaceable charcoal filter that will trap all unpleasant odors. But in this case, the cartridge will have to be changed regularly.

The pump must be powered. For models with a plug, you will need to install an individual outlet, the cable to which is laid from the RCD and the shield. If the device does not have a plug, the connection is made directly from the mains through a 30 mA RCD. After that, you can conduct a test run of the device. During the procedure, you should carefully examine the joints of the elements for leaks, troubleshoot if any.

Connection

For the pump, you need to choose a toilet with a direct drain, so it’s more rational to buy them together, in
same store at the same time.

The pumps are compatible with a straight flush toilet, the oblique flush toilet model will not fit!

Unfortunately, the pump manufacturer stipulates the installation of the unit only superficially, many technical
points are not affected. Therefore, the installation is best done by an experienced master. If you want to install
independently, then a minimum experience with plumbing is required.

Here are some points: If you need to turn the pipe 90 degrees, it is better to do it with two corners
45 degrees to avoid sharp turns in the path of sewage

You need to pay attention to the node connecting
pipe from a pump with a public sewer: "32" polypropylene pipe can be docked with a "40" sewer
wrapping tape on “32” until it fits snugly into “40” and coat the pipe before the joint with silicone sealant. You can do the same with the "25" polypropylene, joining it with the "32" sewer pipe

Further, all
it is joined by standard joints for sewer pipes - "32" or "40" pipes are joined by adapters into a "50" pipe
or more

It will not be superfluous to fasten the joints with self-tapping screws "seeds", the main thing is not to flash the pipes through, categorically not
it is recommended that the tip of the self-tapping screw stick out inside the pipe! It is important, if we approach the side of the main pipe with a drain, make
the connection is not at the “90” angle, but at the “45”, otherwise the water from the pump will “beat” into the wall of the main pipe, creating unnecessary
voltage. And the last: if possible, make a pipe insert from the pump closest to all other utilities to the drain,
leaving to the street, this will exclude the appearance of water pressure in other sewer outlets

Main characteristics of fecal pumps

When choosing a pump for forced transportation of wastewater, factors such as:

• Range of action. The power of the pumping device depends on how far the bathroom is located from the gravity sewer pipe. On average, these indicators are 9-10 m vertically, 90-100 m horizontally.
• Ability to connect additional devices. If the bathroom, in addition to the toilet, is equipped with a shower or washbasin, you can install a common combined pump, rather than using a separate unit for each device. If the toilet is equipped with a large number of household appliances and plumbing, experts recommend the use of two pumps: the first one is for clean hot wastewater, the second one, with a grinder, is for fecal matter.
• The temperature of the transported liquid. For various models, this figure ranges from 40 ° C to 90 ° C. If you plan to connect a washbasin or shower cabin, the maximum temperature of the pumped wastewater should be higher than for transporting waste from the toilet.If a washing machine or dishwasher is connected to the pumping system, a more expensive pump is needed that can withstand the temperature of 90 ° C, on which the equipment works.

Dealing with equipment

1. In appearance, the pump resembles a small plastic box that is installed behind the toilet shelf.
2. The device does not spoil the aesthetics of the bathroom and looks like an additional drain tank.

Fecal equipment does not spoil the appearance of the bathroom

1. Standard models of such pumps are designed to transport fecal matter horizontally up to 100m, vertically up to 10m. Although there are more powerful devices.

Toilets for giving with a pump allow you to pump liquid up to 80-100m horizontally

Main characteristics

When choosing equipment for the forced movement of drains, we recommend paying attention to the following features of the devices:

Transportation distance	This parameter affects the power of the pump. The farther from the bathroom the gravity sewer pipe runs, the larger it should be. The usual capacity for transporting wastewater is approximately 100 m horizontally and up to 10 m vertically, which is sufficient in most cases.
Optional equipment	When the bathroom provides not only a toilet, but also a washbasin and a shower cabin, it is not necessary to install a separate pump for each element of the system. We recommend buying a combined device.
Recommended Fluid Temperature	This parameter is located in the range of 40-90˚С for different equipment options: For example, if you need a grinder only for the toilet, it is enough to purchase a device for cold environments. Another thing is when you decide to connect a washbasin or shower cabin to it.In this case, the maximum allowable temperature of the transported liquid must be higher. Usually the highest price will be at the pump, to which it is supposed to additionally connect a washing machine or dishwasher. This is due primarily to the fact that this equipment drains water into the sewer at a temperature of up to 90 ° C.

Fecal pump with a grinder for the toilet to create a forced sewer system

If a wall hung toilet is installed

In a small room, if you need to save space as much as possible, they often place hanging toilet models. For such sanitary equipment, specially designed devices are offered, in which the width of the tank is approximately 120 mm. It can simply be disguised in a drywall box, in which a frame is also installed for toilet mounts and cistern.

Relatively recently, retail chains began selling toilet bowls that are equipped with a built-in chopper. This device is also designed to connect additional plumbing equipment to it. This type of toilet is not equipped with a cistern.

When the drain button is pressed, water from the water pipe opens and at the same time the grinder turns on. A mandatory requirement for the installation of this equipment is that the pressure in the water supply network must be at least 1.7 bar.

Calculation of the required power

We want to warn you that even if the instructions clearly describe all the main characteristics of the equipment, it is quite easy to make a mistake with the choice.It is not always possible to find a good specialist in this profile, so we will deal with this issue on our own.

On the picture - sewer pump for cuisine

The most common mistake is the wrong choice of device power. For example, if the instructions indicate that the pump can pump liquid horizontally by 80 m, and vertically by 7 m, this does not mean at all that everything will be so.

Why?

Let's figure it out:

1. The operating instructions usually indicate extreme parameters. These situations for the pump are peak, so any unaccounted for load will immediately lead to a malfunction.

1. The characteristics presented in the instructions can be called mutually exclusive. This is due to the fact that when transporting liquid only in a horizontal plane, the pump can advance it by a maximum of 80 m, but when it has to be raised by 2-3 m, the supply range will decrease significantly. We suggest you use the following calculation formula - for each meter of ascent, the horizontal transportation distance is reduced by 10 m.

Installation Features

Do not worry, even if you have never worked with such equipment, you can easily connect it to the toilet with your own hands. When installing a pipeline from a pump to a sewer, you need to know only two parameters - the height and length of the lift.

Forced sewage scheme

They must match the characteristics of the grinder. The rest of the data related to the angle of elevation, the materials used and the configuration of the line can be anything.

Sololift installation

When buying a forced sewer system, pay attention to the fact that different sololifts are designed for different plumbing fixtures. Manufacturers release them separately for: Manufacturers produce them separately for:

Manufacturers produce them separately for:

1. toilet bowl
2. shells;
3. baths;
4. shower cabin.

Pro tip:

The diameter of the inlet of the sololift must correspond to the diameter of the outlet of the drain sewer pipe. Otherwise, the installation will be incorrect.

Installation of forced sewage can be done by hand, calling for the help of specialists only to connect it to the mains. Forced drain is installed according to the instructions.

The best option is considered to be such an arrangement of the pipeline, in which its beginning has a strictly vertical position, and then it runs horizontally, with a certain slope. The main parameters for horizontal and vertical sections of the pipeline, as well as the slope value, are prescribed in the technical passport of the sololift or in the installation instructions.

The figure clearly shows the inverse relationship between the length of the vertical riser and the dimensions of the horizontal one. If the vertical section of the pipeline rises to a height of no more than 1 m, then the length of the horizontal pipe can be 50 m. But if the height of the pipeline is 4 m, it cannot exceed 10 m in horizontal length.

As an example, we present a fragment of instructions for forced sewage:

Insert the drain pipe from the toilet bowl or siphon into the intake device.
Bring the opposite part of the sololift to the sewer riser.
Connect the sololift to the electrical network through a socket or directly into the shield

It is important that the system is provided with a residual current device (RCD).

Thus, it is quite simple to carry out self-assembly if you have at least minor skills. In other cases, it is better to entrust it to specialists. Otherwise, forced sewage systems have practically no restrictions in use and will be an excellent assistant in the redevelopment of housing.

Sometimes it happens that in the purchased apartment, the sanitary and utility rooms are not located quite the way the new owner would like in accordance with an interesting interior idea. Or maybe just in a private house there is a need to re-equip the collector in order to deliver several new household appliances. In these and other cases, the problem of draining into the central riser may arise. Forced sewerage (sololift) will help to resolve the issue without the maximum expenditure of finances, time and effort.

Such a device is a powerful fecal pump with a built-in mechanism for grinding fecal debris and its further transportation through sewer pipes.

It is important to use such a forced pump in such cases:

• Redevelopment of an apartment or a private house with a change in the location of the kitchen or utility room (laundry room);
• The need to install household appliances that work with water in a house or apartment in non-standard places;
• Installation and arrangement of a laundry room or a bathroom in the basement, where the sewer pipeline will pass below the level of the central drain;
• Forced transportation of wastewater from a prefabricated well of a private house to a septic tank, provided that the pipeline is too long.

• So, with the use of such a device, it is possible to avoid complex, dirty and costly repairs for the redevelopment of the building;
• Compactness of the device
  allows you to install it directly behind or under a plumbing fixture, hiding from prying eyes and without disturbing the picture of the interior;
• Sololift power
  allows you to raise drains into the drain to a height of 5 to 7 meters, and transport them to the storage tank at a distance of up to 100 meters horizontally.
• Performance and quality of the grinding mechanism
  allows you to turn fecal effluents containing garbage into water of a mushy consistency, which makes it possible to transport it to the drain through pipes of small diameter (18-40 mm);
• Convenient location of sewer pipes in the room
  due to the small cross section;
• The presence of a special carbon filter in the installation
  , which prevents unpleasant sewer odors from entering the room;
• Relatively low installation noise
  , which makes the use of the sololift as comfortable as possible for all household members.

Connection rules

Installation of the device begins with determining the length of the pipeline and the height of the lift. Both of these characteristics must correspond to the performance of the unit specified in the instructions. Parameters such as the angle of elevation, the material used and the configuration of the line do not matter

There is one limitation during installation: you should try to avoid sharp corners of the pipe. They will create an additional load. Do not use for connecting units and pipes of larger diameter.Normal pressure and grinding of waste will prevent blockages in the pipe with a diameter of 45 mm.

Toilet connection

connects to the toilet as follows:

1. We lay a sewer pipe;
2. We insert connecting elbows into the inlets of the equipment and connect the pipe to the gravity system;
3. We install the unit behind the toilet and fix it to the floor with screws;
4. We connect it to the pipe;
5. We connect the system to the toilet. We connect the chopper with the toilet bowl using corrugations;
6. We connect the pump to the mains through the machine. If the device is supplied with a ready-made plug, then it can only be connected to a personal outlet, the cable to which is led from the shield;
7. Each connection must be fixed by soldering or welding.

Waste water from the toilet will flow into the grinder by gravity, so the outlet of the toilet must be arranged above the inlet of the grinder.

Corrugated pipe should not have a large angle of rotation and have smooth transitions. All pipes leading to the pump must have a slope of 3 cm by 1 m to ensure the normal movement of wastewater by gravity.

Installation in the kitchen

In the kitchen, the equipment can be installed in any convenient place - under the sink or near the wall.

It is important to make the calculations correctly so that the pipes have a sufficient slope, and the line itself is not too long. Otherwise, you will have to install several devices that pump water

At the pumps for sewerage pumping there are practically no installation restrictions in the apartment. The main thing is to follow the instructions and not violate the rules of operation. Then they will become a good assistant in the redevelopment of the apartment and help prevent blockages in the pipes.

Technical specifications

The technical specifications of the drainage pumps for sewerage with a grinder differ depending on the model and are as follows:

• Voltage. The equipment is powered by an uninterruptible power supply with a voltage of 230-380 watts.
• Power consumption. The rated load corresponds to the power consumption of the equipment. For example, if an electric motor consumes 1350 watts of power from the mains, then when it is transformed into a mechanical one, 1100 watts remain. This electric motor has an efficiency of 75 percent.
• Performance. Depending on the power of the device, its capacity is from 20 to 400 liters per hour. It is recommended to buy equipment with a capacity of 20-100 liters for private households, and 100-400 liters for enterprises.
• Water pressure. In submersible pumps, the water pressure depends on the power. The pipe can have a length of 10 to 100 meters.
• Temperature regime. The sewage pump with a chopper fully operates in the temperature range from 0 to 60 degrees. Therefore, it is used for pumping contaminated liquids in harsh climates.

Toilet chopper pumps: features and price

Having decided to redevelop an old building or carry out a major overhaul there, many are faced with a lot of surprises. For example, you drew a beautiful picture in your brain on the topic “How good the apartment will look after. ”and suddenly you discover with surprise that the unfortunate location of communication networks can greatly disrupt your plans.

The most common problem is the inability to equip a new bathroom or move the old one to another room.Usually, in a private house, the sewer system is arranged according to the principle of gravity, that is, wastewater flows down pipes from top to bottom. And if the toilet is installed below the level of the collector of the centralized sewerage system, it will not work. So what is the way out of the situation? Everything is very simple - you need to install a special fecal pump for the toilet, which makes the system partially pressurized.

Ready-made systems with a camera

If it is impossible to ensure a high-quality installation of the well, it is necessary to install the finished system, represented by a plastic container and placed inside the pump:

• The device is immersed in the ground to a predetermined depth.
• Drainpipes are connected to it.
• The drainage system is connected to the pumping unit.

The choice of pumps has a number of advantages over open wells:

• High level of tightness.
• The inclusion of gas filters that remove unpleasant odors and accumulated gases.
• Different parameters of storage tanks: 40–550 l.

Consumers distinguish a number of brands (Pedrollo, Grundfos, Easytec), whose products are equipped with sealed plastic containers of small parameters (sololift). It has the shape of a circle or a rectangle. Units of the Grundfos series have proven themselves well where there is no possibility of gravity water drainage. Structurally, they are presented:

• plastic case;
• nozzles for supply and discharge of liquid media;
• pipes for ventilation;
• carbon filtration to combat odors;
• cutting part for shredding household waste, paper, hygiene products.

The sololift series of pumps are compact products for installation in the shower or toilet without sacrificing design solutions.Among the powerful domestic units, the Irtysh (Novosibirsk) and the Drainage (plastic case) are distinguished.

The principle of operation of the grinder pump

The model for cold drains is presented in a compact box with a chopper-pump hidden inside. The design involves its installation behind the pedestal of the drain tank, but traditionally the box is hidden in the wall so that the view does not violate the aesthetics of the design. The pump requires only an outlet and an electrical outlet to operate.

Schematically it looks like this:

1. The grinder is located at the top of the device body.

2. Drains penetrate into the chopper basket, and in the direction of travel retain a thick fraction, without preventing water from flowing into the body.
3. A specific volume of liquid activates the option to start the motor and pump, while forcing the knives to work.
4. The knife grinds the solid mass, the pump creates pressure, and forces the waste to move through the outlet pipe to the riser, which enters the collector or storage septic tank. The quality of work is determined by the temperature of the pumped wastewater (up to 40 degrees).
5. The contents processed with knives enter the sewer through a drain pipe with a small diameter (45 mm).

A design flaw is considered to be the incorrect upper position of the pump, since the knives fail to grind the contents.

The pressure pipe implies equipping with a check valve that blocks the return of effluents. If you have a shower and a washbasin, it is not at all necessary to mount additional pumps. For this there is a combined system. But, if the bathroom includes several plumbing items, like a washing machine and other functional appliances, it is recommended to install one toilet pump, and the second one for a clean drain.
