Sololift for sewerage: how to choose and install yourself

Manufacturers and models

Not many companies produce individual sewer installations. However, the price range is quite wide.Traditionally, European manufacturers are distinguished by good quality, but high prices. No one will be surprised if we say that Chinese sewage pumps cost less, but their quality is worse. In general, the choice, as usual, is expensive and high quality, or cheaper and…

Forced sewage installations Grundfos (Grundfos) - Sololift (Sololift)

The well-known manufacturer of plumbing fixtures Grundfos (Grundfos) produces pumps for forced sewerage Sololift (Sololift). At the moment, a modified Sololift2 line has been launched. It has no moving parts in contact with drains. The exception is the chopper, but its drive is also “dry”. This makes the renovation less of a hassle. There are several Sololift models for different occasions:

Sololift sewer pumps are not the cheapest equipment, but they work reliably and correspond to the declared characteristics. The firm also supports warranty repairs.

Pumps for toilets, bathrooms, kitchens and technical rooms SFA

This company specializes in the production of sanitary pumps. There are several lines for solving different problems, connecting various devices:

SFA products work reliably and cost a little less than Grundfus. You can choose a model for any combination of plumbing. In general, the SFA sewage pump is a good option. Installation of equipment is standard - put in any convenient place. There is only one limitation - it is better that the branch pipeline starts from a vertical section, if there is one on your route. If this is not possible, the length of the horizontal section should be no more than 30 cm.

The height of the vertical section is calculated taking into account the fact that the horizontal section must have a slope towards the inlet of at least 1% (1 cm per 1 meter of pipe).

Aquatik CompactLift fecal pumps

Toilet pumps Compact Elevator is manufactured by the Chinese company Aquatik. This is a more budget option for individual sewer installations. Differ in low level of noise.

At the moment there are only three modifications:

Aquatik provides a guarantee for its pumps for bathrooms and toilets - 1 year from the date of sale. Violation of operation (the presence of fibrous inclusions in drains) may cause a denial of warranty repairs.

Willo sewage pumps

The German company Willo is known for making reliable devices. Toilet pumps are no exception. Good quality plastic, thick tank walls, reliable pump. There are the following models:

The range of Willo sewage pumping units allows you to solve any problem when it comes to equipping bathrooms and toilets in private homes. For commercial or more intensive use, Willo has other solutions.

Pressure sewer pumps STP (Jemix)

These customized sewer units are made in China. The price category is average. Reviews, as usual, are different - someone is completely satisfied, someone absolutely does not like it.

So, here are the sewer pumps Jemix offers:

It differs from those described above by increased power - some models raise drains by 9 meters. Most of the sewer pressure pumps described above can lift drains up to 4-5 meters. So this is where the Jamixes win.In this parameter, they have only one competitor - Sololift Grundfos with its lifting height of 8 meters. But his price category is completely different (as is the quality, however).

The use of forced sewage

Features of drainage of dishwashers and washing machines

Everyone knows that modern automatic machines (washing machines or dishwashers) must be connected to the sewer in order to divert contaminated used water. But in small city apartments there is hardly a place to install these assistants in the place where the sewer passes, this is typical for both the bathroom and the kitchen.

Yes, and in large cottages, you want to hide the units in the basement, which often serve as the utility floor. In both cases, there is a solution if forced sewage pumps are used. The gist of the solution is as follows:

• It will require the placement of a special sewer installation equipped with a water collection tank and a built-in pump.
• Drains gradually fill the container in which the float switch operates. When their volume reaches a certain value, the pump turns on, pumping polluted water into the sewer.
• Such a forced sewage system is small in size and is installed in an apartment or house in close proximity to the equipment that produces drains.
• It is equipped with a charcoal filter that prevents unpleasant sewage odors from entering the room.

Reliable and efficient system does not require specific maintenance measures, it is only necessary to periodically clean and flush the tank.

Reconstruction or relocation of the bathroom

As mentioned above, the transfer of the bathroom to another, more convenient place can be done in two ways:

1. carry out redevelopment of the apartment, having carried out a major overhaul of the premises;
2. install forced sewage pumps.

The second option is more affordable and faster. But while it is necessary purchase a sanitary pump that meets special requirements. After all, he will have to work with aggressive environments.

Repair

Troubleshooting should be carried out only in service centers, where specialists will accurately diagnose the broken device and select the necessary spare parts. However, maintenance of the sololift can be carried out independently. To prolong the life of the appliance and prevent the formation of an unpleasant odor, it is necessary to regularly clean the tank with a detergent.

To do this, disconnect the device from the power supply and remove the cover. Then the composition should be poured into the storage tank and left in this state for 10-15 minutes. Further, without installing the cover in place, you need to connect the device to the network and press the drain. After rinsing the tank is completed, you need to turn off the device again and put the lid back on.

In the next video, you will find the selection, connection and principle of operation of a compact sewer pumping station Grundfos Sololift 2 WC-3.

A brief overview of popular Sololift models

There are a lot of popular and reputable manufacturers and brands on the market for such equipment. Let's take a look at some of the models.

Expert opinionValeriy DrobakhinVK design engineer (water supply and sewerage) ASP North-West LLCAsk a specialistThe pumping station model is not equipped with a grinder, so use to connect to the toilet she can't. It also prevents food waste from entering the sewer system, which can cause damage to the unit.

Sololift C-3 is used to remove large volumes of liquid. This pumping unit is able to remove wastewater, the temperature of which reaches 90°C.

Installation of a forced sewage pump Sololift

Despite the ease of installation work on the installation of Sololift pumps, some rules should be followed to avoid mistakes. The drain pipe must not have bends, as this will make it difficult to push out the drain water. If planned installation of a pumping station to drain liquid from shower cabins (bathrooms), it is recommended to connect equipment at low points. In addition, the drain must be equipped with a filtration system so that hair and other small objects do not get inside the equipment.

Option to install a pumping station in the toilet

Before carrying out installation work, it is necessary to check the complete set of the installation and make sure that there is a check valve (in its absence, dirty water will flow back into the system). You also need to install a material on the floor under the unit that will absorb the vibrations of the pump. The pipes must be tightly connected to each other using sealant and seals. As a rule, manufacturers attach all the components necessary for installation, so there is no need to purchase self-tapping screws and other fasteners.

Connecting the pump nozzles

Upon completion of the installation work, the system is checked for the quality of the connection. If leaks occur, it is necessary to eliminate defects in the joints.

Model range of pumping units Sololift

Let us consider in more detail each of the models of Sololift pumping systems:

WC-1. The compact dimensions of this unit make it possible to make it an element of the sewer system in small rooms. The device is complemented by a powerful pump and chopper, capable of crushing even things like sanitary napkins. Also, the device has an alarm system that informs about interruptions in its functioning. Due to the convenient design, the unit can be repaired and serviced during use without disconnecting from the sewerage system.

Size specifications:

• weight 7.3 kg;
• dimensions - 347 mm by 426 mm by 176 mm;
• capacity - 9 liters.

This particular unit is fixed to the floor with screws or dowels. Most often, it is placed behind the toilet at an approximate distance of 15 cm from it.

To attach the installation, you need to make several holes in the floor for dowels by drilling, then fix it with self-tapping screws. Usually, fasteners are sold complete with Sololift, and without the need to buy them separately. Moreover, foreign elements can cause damage to the unit.

WC-3. This model has similar features to the WC-1. They have the same overall dimensions. The main difference is that 3 pipes can be connected to it to drain the drain liquid at the same time from several places - a toilet bowl, a shower cabin, a sink, and so on. When thinking about buying this option, do not forget that the temperature of the drains should not be higher than +45 degrees. СWC-3. This unit is compatible with any kind of plumbing, because it is equipped with a powerful pump and grinder. He is able to process almost all garbage, with the exception of stones.The device is equipped with a sound signal, is not subject to overheating, and can restart itself.

Dimensions:

• weight - 7.1 kg;
• dimensions - 539 mm by 496 mm by 165 mm;
• capacity - 9 l.

The bottom of the housing is rounded and therefore solid particles do not accumulate in the tank. And this fact greatly simplifies the process of caring for the device. It doesn't need to be cleaned too often.

D-3. This model has the minimum dimensions. It does not have a grinder, so it can only be used for pumping clean wastewater. That is, this unit cannot be connected to the toilet. The device is fastened with dowels to the floor. If you connect this particular model to a shower cabin, then a filter must be installed to trap hair and other small particles. The unit must be placed lower than the drain level.

The bottom of the housing has a rounded shape, so small solid particles do not linger in the tank. Main overall parameters:

• weight 4.3 kg;
• dimensions - 165 mm by 380 mm by 217 mm;
• tank capacity - 2 liters.

C-3. It stands out from the background of all other models from the Sololift line in that it can pump hot liquid. The usual temperature at which the unit can work at least constantly is +75 degrees. And for short periods of time, up to half an hour, it can also pump ninety-degree runoff water. These types of appliances are used for dishwashers and washing machines.

Overall parameters of the model:

• weight 6.6 kg;
• overall size - 158 mm by 493 mm by 341 mm;
• the tank holds 5.7 liters.

Variety of systems and their purpose

The forced sewage system is a pump, often equipped with a grinder.The size of the structure makes it easy to hide it behind or inside plumbing fixtures. The system's job is to send sewage flow into a septic tank or central sewer pipe.

Often, the Sololift system pump is very powerful and is capable of withdrawing liquid over a distance of 7 m in a vertical pipeline and up to 100 m in a horizontal one.

Forced system sewerage in the bathroom

Devices for forced sewerage are represented by a wide range of models. The marking indicated on their body tells the user about the scope.

WC-1 is a design equipped with a new generation shredding mechanism capable of shredding small household waste (toilet paper, hygiene products). The installation of such a device is carried out for wastewater containing fecal matter. The pump is suitable for toilet bowls and washbasins located below the level of the sewer pipe (in the basement). The engine is equipped with a thermal protection function and in case of overheating it turns off and then restarts. The device is mounted in close proximity to the toilet. most often it is connected to the outlet pipe of the compact bowl.

WC-3 - such a system is similar to the previous one. Its only difference is 3 branch pipes, as indicated by the number 3 in the product labeling. The device makes it possible to connect not only a compact, but also a sink. shower cabin. bath or bidet at the same time.

CWC-3 - the first letter "C" in this marking means "compact". Due to its relatively small dimensions and flat shape, it is perfect for mounting in a wall niche behind a wall-mounted toilet or washbasin.

C-3 - installation for pumping gray wastewater without large inclusions.The device is not equipped with a cutting device, so the connection of such a model to the toilet is excluded. The advantage of this system is the ability to remove hot drains up to 90°C. Installation is possible for sinks, washing machines, etc. The presence of the number 3 in the model name indicates the possible connection of 3 simultaneously working devices.

Important! The S-3 device is capable of pumping hot drains with a temperature of 75 ° C continuously, above this indicator working hours are limited to 30 minutes. D-3 - Just like the previous model, this device cannot be connected to the toilet

In addition, it is not designed for drains with elevated temperatures. The maximum temperature of the pumped liquid is 50°С. Such a system can be connected to washbasins and showers. The rounded shape of the bottom of the device does not allow it to clog

D-3 - Just like the previous model, this device cannot be connected to the toilet. In addition, it is not designed for drains with elevated temperatures. The maximum temperature of the pumped liquid is 50°С. Such a system can be connected to washbasins and showers. The rounded shape of the bottom of the device does not allow it to clog.

For the correct operation of the system, it is necessary to initially select the appropriate model. Naturally, each additional feature in the system makes it more expensive. It makes no sense to overpay if you plan to connect one point of drain water without large inclusions.

Advantages and disadvantages

The question of what a sololift is can be given a complete answer only by understanding its advantages and disadvantages. Pros:

• The ability to install any plumbing fixture, sink, sink anywhere in the house.
• The strength and reliability of the installation.The brand has proven itself for a long time and offers only the best solutions.
• The cleaning of the sololift is practically not carried out, because all residues are removed with the flow of effluents.
• The unit runs quietly. It uses a submersible pump that does not suck in air, that is, there is no characteristic noise from it. It also prevents the familiar sound of the movement of drains through the pipe from arising.
• The compact size allows you to install a solo lift for the toilet, right behind it, without taking up valuable space in the bathroom. The volume of the device is within 3-5 liters, while the throughput is 40 liters per minute, which is several times higher than this indicator of any plumbing device.
• Due to the presence of a grinder, solid waste is ground into small fractions, which prevents them from clogging pipes.
• Temperature and pressure do not deform the sololift chopper pump tank.
• The design provides for a carbon filter, it eliminates all unpleasant odors, even in the process of accumulating them in the tank.

There is a minus, and it is only one - it is the impossibility of autonomous operation if there is no electricity. That is, in emergency situations, forced sewerage will not be able to function. But this drawback can be overcome by installing a gasoline generator or using other energy sources. In extreme cases, until the breakdown is repaired, simply do not use the plumbing fixture that is connected to the sololift.

Sololift pumps for sewage: equipment prices and installation recommendations

Grundfos sewage pumping units cannot be classified as budget units. At the same time, the cost depends not only on the modification and functionality of the device, but also on the pricing policy of the store where the equipment is purchased.The outdated Sololift + series has already been discontinued. This moment also affects the cost of pumps.

The cost of pumping equipment Grundfos:

Model	Dimensions, mm	price, rub.
Average prices Sololift plus

CWC-3	165x280x422	25300

Interesting fact! Some models are capable of transporting liquid through a water main for a distance of up to 100 m.

Recommendations for installation and operation of equipment:

• the minimum distance between the pump and the plumbing fixture or wall is 1 cm;
• the drain of the shower stall is connected from below and needs an additional installation of a filter in order to protect the unit from hair ingress;
• before starting, the inlet valve is checked so that there is no backflow of liquid;
• it is desirable to use a vibration-isolating material that will reduce the noise level;
• pipe joints must be treated with sealants and the reliability of the connections must be checked;

The scheme for connecting Sololift to the sewer is quite simple, but requires certain knowledge of the system itself

• in order to protect yourself before performing repairs or maintenance, be sure to remove the fuse and turn off the pump from the outlet, while making sure that there is no possibility of accidental switching on;
• pumps are combined with any kind of pipes, including plastic ones.

Sololift pumping units are ideal for organizing a forced sewerage system with unlimited possibilities that do not impose restrictions on planning. This advantage will be appreciated by owners of small apartments.The equipment does not require a lot of space, is installed with minimal use of tools (all the necessary adapters are already included in the kit) and efficiently performs its work, which affects its cost.

How sewer works

Any sewer works on the principle of gravity flow of water downhill. The higher the slope of the pipe (up to a certain angle), the greater the speed of water movement and the less likely the formation of blockage. In private houses, this problem is solved by installing all the collectors in the basement, thanks to which it is possible to ensure the correct slope of the pipe connecting it to the plumbing fixture. In the apartment, the central collector is installed vertically, so the angle of inclination of the pipe depends on the level of the entrance and the installation height of the plumbing fixture. If, for some reason, the entrance to the central collector is at the same level or higher than the exit from the toilet, the sewer will not work normally. This fully applies to pressure sewers, because in them the pump is installed at the inlet to the central collector.

correct sewer pipe slopes

Sololift for sewerage: basic information about pumps

The functioning of the sewage system is based on the principle of moving water by gravity due to the slope of the pipeline. Normal operation of communications is possible only if there are no blockages.

The Sololift pump is designed to remove wastewater that cannot be discharged by gravity

In private sector homes, collectors are used to solve this problem. The presence of a tank in the basement allows you to install the connecting pipe leading to the plumbing fixture at the right angle.In apartments, the collector is mounted in a vertical position. In this case, the degree of its inclination depends on the height at which the point of consumption is located and the location of the entrance.

If the point of entry of the pipe into the central manifold is located above the exit from the plumbing fixture (toilet bowl) or at the same level with it, then the sewer system will not be able to fully operate. This also applies to pressure communications, since their scheme involves the installation of a pump at the entrance to this tank.

Exists several solutions this problem:

1. Set consumption point higher.
2. Lower the manifold inlet level.
3. Buy Sololift for sewerage.

Sololift - compact sewer installation

The first two methods are accompanied by significant difficulties, because it is far from always possible to perform these procedures without compromising the comfort of operation. Therefore, the purchase of pumping equipment for sewage is the only optimal way out.

Note! The greater the slope of the pipe, the higher the speed of movement of the liquid, on which the likelihood of blockages depends

Advantages and disadvantages of Grundfos Sololift sewer pumps

Sololift is a pumping equipment designed for sewage. The main function of these installations is the forced pumping of wastewater through pipes. They are used in those rooms where it is impossible to organize the necessary slope of the line, which ensures the removal of waste fluid from points of consumption by gravity.

The presence of a carbon filter prevents the spread of unpleasant odors

Points of consumption include:

• shells;
• bathtub and shower cubicle;
• toilet and bidet;
• sinks and other plumbing fixtures.

Due to its compact size, this type of equipment can be installed in rooms with a small area, so it would be advisable to buy a Sololift for a bathroom, toilet or kitchen. The special design with an inclined bottom prevents the formation of sediment in the form of sewage and fecal matter. The included equipment increases the rate of fluid supply, due to which a vortex draft occurs in the system, eliminating sediment from the base of the tank.

The manufacturer accurately calculated the proportions of the device. With a tank volume of 3-5 liters, the pump is capable of developing a high flow rate of waste fluid - 40 l / min. Plumbing fixtures themselves do not have such a powerful drain. Improved performance made it possible to abandon the use of a large tank, simplifying the installation of equipment in inconvenient places.

With a small volume of the tank, the pump is able to develop a high flow rate of the waste liquid

The unit is very quiet as the pump is submerged in water all the time. Noise during the flushing of the toilet is usually due to the movement of liquid and air in the pipes. AT case with this pump does not occur, because the equipment does not capture air currents. The operation of the device is fully automated. The installation diagram assumes only the connection to the reception point, pipe and socket with a voltage of 220V. With this procedure, you can cope on your own, without resorting to the services of a professional plumber.

The most important advantage of Sololift pumps is their reliability and the possibility of redevelopment. Thanks to this, there are no difficulties with height differences during the installation of equipment. In addition, the possibilities for placing plumbing in the room are expanding. The body structure is very durable.It can withstand the influence of high temperatures and pressures without deformation changes. The presence of a carbon filter eliminates the spread of unpleasant odors.

Rugged body design can withstand high temperatures and pressures

The disadvantages of the equipment are not so many. First, the pumps need a constant power supply. Secondly, the cost of Danish installations is quite high.

Important! All connections between the elements of the system must be tight. Only under this condition will the sewerage work properly.

Installation of sewer station Sololift

The installation of the Sololift station is notable for its simplicity, for its implementation you do not need to call a specialist, and it is quite possible to cope with this task on your own.

The main criterion for proper installation is the free passage of water from the pumping station to the sewer pipe. It is necessary to remove all obstacles that prevent the station from pushing water upstairs if it is in the basement.

Installation Features

If the Sololift pump is installed near the toilet, then its distance from the station should be no more than 40 cm for correct operation.

The installation is carried out to the outlet pipe of the toilet bowl, while the junction must be well fixed and treated with a sealant.

After the dirty water goes to the common sewer riser, the water is drawn back into the tank and when it is full, the pump turns on again.

To power any model of the Sololift system, a conventional 220 W socket is sufficient.

The pipes leaving the pumping station can vary in size from 18 to 40 millimeters. This helps to lay them out so that they are not visible from the outside, for example, they can easily fit behind drywall sheathing.

An example of installing a pumping system behind the toilet can be seen below.

Sololift installation behind the toilet

The box size of this Sololift model is about the size of a toilet bowl, but there are also more compact sizes for those rooms in which there is not enough space for installation.

Stages of the installation process

Despite the ease of installation of the Sololift system, you must follow the installation steps indicated in the instructions.

The main ones are:

It is very important to keep a distance of at least 10 mm from pump to walls or plumbing;
If you are connecting shower drain, then it must be connected at the lower points. Also, the drain in this case is equipped with a filter so that the hair does not get into the pumping station;
Before starting the pump, the valve must be taken into account at its outlet into the sewer to prevent backflow of water;
There must be anti-vibration material under the pump device;
When connecting pipes, they are tightly joined and sealed with hermetic materials;
Do not use metal screws or other devices, all the parts necessary for installation are already included in the kit;
After connecting all the pipes, the pump is plugged into the socket and its operation is checked. The Sololift device is suitable for connection with all types of pipes, including plastic pipes

Start the pumping station only after you make sure that all the bolts are tightly tightened and the sewer pipes are securely connected to the system

The Sololift is suitable for connecting to all types of pipes, including plastic pipes. You should start the pumping station only after you make sure that all the bolts are tightly tightened and the sewer pipes are securely connected to the system.
