Why the gas pipe is electric: causes and ways to deal with the problem

Why does the circulation pump make noise in the heating system? Troubleshooting

Choosing the right circulator will help prevent annoying noises. The store presents units with motors of two types:

Dry. Devices of this type cope with high loads. The rotor stays dry. Cooling occurs with the help of a fan that will make noise.

Photo 1. Circulation pump for heating systems from the manufacturer Wilo.There is a fan on the back to cool the device.

Wet. The pump is located directly in the water. The unit is protected from overheating by an almost silent coolant.

Attention! Dry type devices will create discomfort due to the sound of the fan running. For domestic needs, a wet type of pumps is used. They are installed directly in the room.

They are installed directly in the room.

Extraneous hum, noise or rattle of the device can be associated with some system malfunctions. The most common problems:

• Unstable voltage.
• Poor quality installation.
• Air lock in the system.
• Power and parameters mismatch.
• Hardware failure.

Unstable voltage

With voltage drops, the operation of the pump is uneven. Lack of synchronization leads to intermittent circulation of water in the system, extraneous sounds occur inside radiators or pipes.

To find out the cause of noise, diagnostics are carried out, which makes it possible to identify malfunctions in the functioning of the device. Such a procedure requires the involvement of a specialist with additional equipment.

Noise due to mounting error

Rustle occurs due to increased cavitation loads. The installation of a hydraulic compensator will help to avoid the problem: a membrane tank that helps regulate static pressure when heated. This device draws excess moisture from the system and prevents water hammer. A properly installed hydraulic compensator will significantly extend the life of the pump.

Pump whistles due to air locks

Whistling sounds that occur when heating is started are often caused by air locks. Air enters the system when pipes and radiators are filled with water.

What to do if the pump suddenly starts to whistle? To fix the problem, Mayevsky cranes are provided in the design - special holes closed with a screw plug located in the upper parts of the radiator.

Open the device with the pump off using a screwdriver or wrench.

Reference. Installing automatic air vents will help to eliminate air congestion in time.

Mismatch of parameters and power

Noise when turning on the heating is sometimes due to the installation of an unreasonably powerful pump. The technical characteristics of the unit specified in the instructions necessarily correspond to the design parameters of the entire system. The pump becomes one of the final purchases when the exact length of the pipes and the number of radiators are known. The overall performance of the device at maximum load is calculated relative to low outdoor temperatures in the winter season.

The device buzzes and cracks due to equipment failure

Common problems with a circular pump include a defect in the rotor or impeller. In addition to constant noise, this problem leads to poor system performance.

The hum is a consequence of technological gaps that have increased over time and shaft trembling. Repair and replacement of adjusting washers will solve the breakdown.

Burning motor windings can crack. Correction of this defect is best entrusted to a specialist.

Knocks out an automatic device with an RCD

An RCD machine can knock out due to the power supply system for the following reasons.

1. The load on the meter is too high.When connecting a washing machine to the network, in this case it will be necessary to turn off other powerful current consumers, for example, an electric stove. air conditioning or microwave oven.
2. Damage to electrical wiring or outlets. To check and find the cause, you will need to connect a device with approximately the same power. If the machine with RCD knocks out again, then the reason lies in the wiring.

Replacement or adjustment of the RCD must be carried out by specialists. Otherwise, unauthorized intervention in the design and settings of the machine, traffic jams or meter may cause overheating of the electrical network and its ignition.

The washing machine is shocked: the main reasons

If your washing machine began to beat with current, then this indicates that a surge of electricity is passing through its shell.

There are many reasons, but experts identify 3 main ones:

1. Faulty washer wiring. If there is such a breakdown, then it makes no sense to use household appliances, since in any case you will suffer from strong electric shocks, especially if the contact of the wiring with the case becomes better. In order to correct the situation, you will need to check all the wires of the equipment for integrity.
2. The equipment is constantly in a damp place. This reason is most common, since the washer is mainly installed in bathrooms, and this is the dampest place. Of course, if you also touch the unit with wet hands, this will not lead to good. This trouble is inherent in all manufacturers of washing machines, of course, new models may hit less, but the problem remains. This situation can be called the manufacturer's mistake, because they believe that in every house where the washing machine is installed, there is a good ground.
3. The heating element or the engine in the technique has broken through. If one of these parts breaks down, then the current will break through to the case, in such a situation it will be enough to replace the broken part with a new one.

If the machine is beating with current, you need to look for the reasons why this is happening. As already mentioned, not only washing machines break when touched, but also a refrigerator, a dishwasher, a system unit, sometimes voltage can prevent washing due to the current flowing into the water. The only way to fix this is if you have identified the source of the problem, because if a woman says “I am electrocuted when touched”, this will not show you the main source.

If you live in a house and you have grounding, but rails are installed nearby, then most likely it is the reason that you were struck by a current from a typewriter, because it is this fact that breaks through electricity. Therefore, before looking for the reason that the dishwasher hit you in the house, think about more global facts, for example, that you have accumulated a buy charge.

The first source is water

Water, as a wonderful dielectric, is the first threat of electric shock in the bathroom. The most common situation is when water flowing from a tap transmits weak impulses from current exposure. At the same time, the damaging effect on a person can be different: from mild discomfort to tangible discharges that turn an attempt to take water procedures into a real torture with electricity, thereby making it impossible to use the bathroom.

The reasons

There are two reasons for the appearance of current in the water flowing from the tap:

• The most common variant of current leakage and water damage is a faulty heating element of your water heater.Over time, solid metals and alkalis present in the plumbing system, under the influence of heating, begin to settle on the walls of the boiler and its heating element, turning into a thick layer of scale, which, coupled with corrosion, corrodes the body of the heating element and the insulation of the wires connected to the heating element;
• The second reason is the human factor. It is no secret that the general impoverishment and extortionate tariffs for the provision of public services, which include low-quality electricity supplied to the population, are forcing the people to find new ways not to pay this state. Magnets on water meters, all kinds of home-made devices plugged into a socket to rewind meters in the opposite direction, etc. Regarding bathrooms, many innovators practice connecting the zero phase to metal pipes. There would be no danger in this if all the neighbors in the riser had metal pipes. But if the neighbor from above connected the neutral wire to the riser, and the neighbor cut the pipes from below and put in plastic ones, the stray current will “come” to you.

Experienced Tips

After listening to the experts, we could not disregard the opinion of ordinary people who faced the problem when the shower cabin was electric. And here's what they suggested:

• ask an electrician to equalize the potentials of the cabin and the water supply using a copper wire clamp that is attached to a steel pipe;
• the problem may lie in the fact that during the installation of the shower stall, fittings or wiring were accidentally touched;
• turn the shower plug upside down;
• be sure to put a separate RCD for the shower;
• ask the neighbors above and below if they are shocked, and if the problem is common, solve it together.

Why does the washing machine get electric shock?

No protective conductor PE. Electricity damage occurs in 2- and 4-wire networks, where there is no special PE conductor (it is provided in modern TN-S power supply systems). The stability of the automation is ensured by a surge protector installed at the inlet to the washing machine. Network filters are designed so that the current flows from the capacitors through the PE conductor. In a 2-wire network, without a PE wire, the electric current is unable to drain - it simply accumulates on the case. Therefore, when a person touches a typewriter, it passes through the body into the ground. Hence the small bumps.

Short circuit in the wiring of the phase and ground wires

The fourth reason is quite rare, but maybe this is your case. For example, you may not have any electrical appliances in your bathroom at all - there is no washing machine, no boiler, etc. At the same time, there are also no neighbors, and you live in your own separate wooden house. All wiring is made with a three-core cable with a grounding conductor, the shield circuit is assembled according to the rules.

And yet, in the bathroom you still have an electric shock. How is this possible?

There are two reasons here:

poor ground loop - they hammered one corner into the ground and considered it sufficient, or the contact was broken at the point of connection to the loop

phase closure to the ground conductor, and in any of the wiring lines, not necessarily in the bathroom

Well, as a rule, at the same time, you naturally do not have an RCD in the electrical panel. A simple machine in this case will not turn off, since the current is too small for it.

This can happen:

as a result of screwing the self-tapping screw into the wall when it simultaneously hits the phase and the yellow-green PE conductor

when heating the insulation and shorting the wires in the lighting lamp

Short-circuit phases and ground wires in a socket with a ground contact

due to a short circuit in an ordinary plug. The insulation of the phase conductor is rubbed against the pressure plate. And it is usually grounded.

Don't trust cheap carriers and extension cords yet. They need to be turned off first.

And since this conductor is connected to a common ground bus in the shield, then the potential along it will diverge throughout the house and apartment.

You will only feel it first of all in the bathroom, where it is damp and damp. The presence of potential is checked with a screwdriver indicator, and it is better to use it with a neon light bulb, and not with an LED.

Causes of the malfunction

No grounding. According to the technical requirements, the electric stove must be connected to a grounded socket, it must have 3 wires: zero, phase and earth. The latter is needed just in order to protect you from electric shock. Modern houses usually have a grounding conductor. But in Soviet-built buildings, the sockets are two-phase, there is no grounding factor there.
wear of insulation. The entire electrical network inside the device is built on wires and contacts.

The most important thing here is that each element is isolated. To do this, all wires are covered with a layer of PVC. This is a fragile plastic layer that can be damaged during transportation.

And over time, the isolation itself can collapse. If a live wire comes into contact with the metal parts of the system, voltage will be transmitted to the case. When touched with wet hands, you will feel a small discharge.
Broken TEN.The heating elements are located in all heating parts: in the burners and in the oven (there are from 1 to 4 heaters). Any tubular electric heater consists of a conductive filament and an insulator around it that transfers heat but not current. If the insulating material is damaged, the electric stove will generate electricity and heat up even when it is turned off.
Water got in. If the tile is next to the sink or the soup boils out of the pot frequently, liquid can enter the system and complete the circuit on the metal case of the appliance. The good news is that the fluid can be removed and the system sealed. There are no serious holes in the wiring. But if, after water gets in, when you turn on the burner, it knocks out plugs, you need to call the master and check the entire structure.
Electrical defects. If you dismissed all the previous reasons, but it is still easy to get hit from the body of the plate, it is possible that the phase and neutral wires were mixed up when connecting. You won't be able to fix it on your own.

Why does it shock from tap water: reasons

How to learn to find a place where you beat current? In other words, you need to examine the armored wires and find the area where the current is leaking. For this, a special screwdriver and rubber gloves are used so that the master is not killed by electricity. The screwdriver is called a tester

It is worth noting that if we are talking specifically about the bathroom, then it is important to remember that the sockets of this room have protection with an IP 44 rating.

As a rule, in apartment buildings with a modern configuration, there are common house and individual systems of potential equalization.

The essence of the system is to combine the pipeline of such plumbing equipment as:

• Sink;
• Bathroom;
• Battery;
• Toilet, even if each pipe is installed individually on each appliance, etc.

Before use, be sure to check the performance of the system

It is worth noting that even if a system of excellent quality is installed, checked for malfunctions and they are not detected, but still there is a beating current, then you need to pay attention to the neighbors. It is possible that their equipment is installed either illiterately, or the wires are operated with violations

Some have no idea that it is strictly forbidden to throw wires on pipes, no matter for what purpose this is done, it can cause electric shock. To be more precise, everything will be fine for the neighbor, and those who live near him will have severe problems, and even a blanket in the bedroom can be shocked if the bed is near the battery, on which the wires are thrown.

Features of gasification of residential buildings

With the help of gas in the house, you can successfully organize heating, hot water heating, and cooking.

Gas equipment is reliable and diverse, and the cost of blue fuel is usually lower than the use of electricity, solid or liquid fuel for the same purposes.

In addition, gas lines fail extremely rarely, but power outages are common. Stocks of firewood, coal, diesel fuel and other similar energy carriers have to be constantly replenished.

The main problem with natural gas is its danger to human health and its ability to explode. Even a small leak can lead to poisoning or an explosion.

That is why the requirements for the installation of gas communications are very high, you should not even think about doing all the work yourself.

In order to properly introduce gas into a private house, a special unit is used, which is called a reducer for reducing gas pressure.

To begin with, experts do not recommend saving on materials or system elements. Pipe laying of dubious quality and unprofessional installation are unacceptable.

Gas pipes almost always need to be laid in an open way (except for underground sections of the highway). They cannot be hidden under any decorative elements to improve the interior.

It is not recommended to introduce a gas pipe into the house through the thickness of the foundation; for this purpose, a hole is made in the outer wall and a sleeve is inserted into it for protection

It is recommended to avoid plug connections whenever possible. All places where pipes are connected must be located in such a way that at any time the point of contact can be examined and repaired if necessary.

Do not lay gas pipes inside the walls or in the thickness of the foundation. This rule also applies to other elements such as architraves, door frames, window frames, partitions, etc.

In some cases, it is allowed to lay a gas pipe in a wall niche, but this point must be clearly reflected and justified in the project. Special requirements are also imposed on the slope of the pipes.

Horizontally, the position of the line is allowed to deviate by only 3 mm towards gas appliances.

Vertically, no deviations are allowed, but the riser may have a slight slope: no more than 2 mm per meter. It should not pass through living quarters, through a toilet or bathroom.

The gas riser should be located in the stairwell, often through the kitchen.

You will also have to carefully monitor the installation of shut-off valves. So, the position of the central axis of the plug must be strictly parallel to the wall along which the pipe runs.

When choosing the position of the valve, make sure that the position of the locking device is not blocked by the wall. From the ceiling and from the walls, the gas pipe should be located at a distance of 100 mm.

Gas pipes are fixed along the wall not close, but at a short distance so that communications remain available for routine inspection and repair

The gap between the wall and the pipe can vary from the size of the pipe radius to a limit value of 100 mm. This clearance is necessary so that the structure can be easily examined.

A distance of 2.2 m should be maintained from the floor. Gas pipes are placed on special strong supports, sagging of the structure is unacceptable.

Therefore, it is necessary to make sure that there are no gaps between the bracket and the pipe. All these important points are taken into account in the project, which must be preliminarily drawn up by specialist engineers.

Gas pipes should be laid at least 30 cm from the electrical panel, and at least 25 cm from open wiring. From the hidden cable should retreat at least five centimeters.

No grounding

In many homes, the wiring does not have a ground connection. Modern household appliances are designed for the fact that part of the current will go through the case from the capacitors of the device. If grounding is not provided in the apartment or house, then gradually a slight charge will accumulate. As a result, when touching the washing machine, the user will feel a slight tingling sensation.

You can fix the problem. For this, grounding must be done. In a private house, this will not cause any particular difficulties. But in multi-apartment buildings made according to the old layout, there are no ground terminals in the shields.

Prevention of new breakdowns

In order to avoid the recurrence of problems, protect yourself from electric shock and extend the life of the water heater, it is necessary to take a number of preventive measures:

1. Regularly clean the boiler tank from scale formation. This procedure will significantly increase the performance of the heating element and reduce the likelihood of new breakdowns.
2. Install RCD. The device catches all leaks and automatically disconnects the water heater from the mains, protecting the owner from electric shock.
3. Routinely inspect wiring for damage and contamination.

Is static electricity dangerous?

The effect of static electricity on the human body has not yet been studied.

There is nothing wrong with a person's ability to generate an electric charge. The maximum harm that we can get from this is the unpleasant sensations in which we cry out: “Oh, the electric shock!”. Such blows do absolutely no harm to health and life. However, this is only the case if electrical discharges occur infrequently. But what if a person is shocked regularly?!

It is impossible to say for sure how long-term exposure to static electricity affects human health - this issue has not been fully studied. However, those few experiments in which a person was subjected to prolonged exposure to static electricity, speak of such consequences.

The organ that is affected	Effects
Nervous system	The main reason that this day turns out to be a huge stress for you is that you rush into things at the last moment. Therefore, try to think over gifts in advance (and even look after them), make a festive menu.
The cardiovascular system	Heaviness in the stomach, overeating and nausea are signs that you thoughtlessly approached the preparation of the menu. Even if you cannot deny yourself the pleasure of preparing a lot of dishes, make portions small.
Respiratory system	It is difficult to feel the approach of the New Year when you are standing in an apron and preparing different dishes with both hands at the same time. Therefore, before you start cooking, create the right mood in the house. Decorate your home with a garland, turn on Christmas music, put up a Christmas tree (one smell of pine needles is worth something!). Believe me, in such an environment, the New Year's fuss will seem like a holiday!

What to do

First of all, make sure that all household appliances are grounded. Here the situation is significantly complicated by modern trends. Today, residents everywhere change metal water pipes that served as a natural grounding conductor for plastic risers, which do not perform the originally intended function of grounding the house. To avoid such problems in the future, it is recommended:

• Install a voltage stabilizer for potentially dangerous electrical appliances.
• Replace sockets (especially kitchen/bathroom) with ceramic models that have a minimum protection class of IP44 / IP54.
• Examine the wiring with a special device that will indicate breaks in the line.
• Change the power line to the kitchen, bath, toilet. Use a special, moisture-resistant electrical cable.
• To the most powerful household electrical appliances, draw a separate straight line with a separate machine.
• Install fuses that blow if there is a current leak.

Remember: all electrical work is potentially life threatening. Therefore, it is advisable to entrust the search for the reasons for the appearance of current in the water tap and, accordingly, the elimination of the problem to professional electricians!”]

Poor repairs and blockages as the causes of the hum

If the faucet hums several times a day, then one of the neighbors can repair communications. In this case, the elements may not be tightly connected to each other. Eliminating installation flaws and good fixation of pipes will help get rid of an unpleasant hum. If the pipes are close to each other, the water that passes through them can create vibration and lead to their mutual collision. A similar problem is solved by wrapping each channel with foam insulation.

You can diagnose a clogged channel by disconnecting the tap or mixer from the pipe and assessing its condition. The build-up on the walls leads to the fact that the resulting jet stream of water creates small vibrations and noise. Since most often the accumulation of dirt that is contained in the water supply occurs at its ends, you can try to clean them. The end sections are prone to clogging not only in metal pipelines, but also in polypropylene and plastic ones. The diameter of the taps of the mixer is different from the section of the channel itself, which contributes to the accumulation of dirt in such areas.

Troubleshooting

The reasons why a broiler is shocked can be very diverse:

1. Destruction of the insulation of the heating element.The source of this reason is in the destruction of the PETN shell or periclase. When this shell is destroyed, the heating coil is exposed, which is constantly under high voltage. When the shell is destroyed, the spiral begins to actively interact with the best current conductor - water. As a result, slight electrical discharges are released, resembling a slight tingling. You can fix the breakdown yourself by replacing the worn heating element.

2. Incorrect connection of the boiler can also cause electrical discharges. Often, many people confuse zero and ground by connecting the heating element incorrectly. To fix this problem, you need to reconnect the wires. The earth cable is usually colored yellow-green.

After installation, it is important to check the wires not only outside, but also in the outlet. When in doubt, you should contact the experts

Boiler connection

3. Touching a bare wire to the housing can also cause electrical discharges. This problem occurs if the insulation deteriorates or wears off on any of the wires. Electricity leakage occurs if a bare wire touches the computer case. To fix the problem, you need to disassemble the device and find a bare wire that needs to be repaired or replaced with a new one.

Bare wire on TEN

4. Faulty neighbor's water heater. This may also cause a problem. In this case, electricity will be transmitted through metal pipes. If this situation occurs, turn off the boiler immediately. After turning off, you need to touch the water: if it no longer stings, then the reason is in the neighbor's boiler. Residents should be notified immediately of the breakdown.

Conclusions and useful video on the topic

The first video contains information that will allow you to understand some of the causes of current leakage and understand how to deal with them:

The following video shows how you can identify the presence of a current leak yourself:

The presence of a discharge on the body of the gas stove indicates that it is faulty or there are problems in the electrical network. The situation is complicated by the fact that "blue" fuel is flammable and explosive. Therefore, the operation of the stove should be stopped immediately after the first signs of a malfunction are detected. This will help prevent accidents.
