Why the tap is droning when the water is turned on: possible causes and solutions

Residents of apartment buildings know firsthand about this phenomenon. Sometimes it's a barely audible rumble, and sometimes it's felt over all the risers or houses. Today we want to talk about why the tap is buzzing when the water is turned on. At first glance, this is not a very serious problem, but sometimes it causes certain inconveniences. Let's understand why this problem arises and what methods exist to combat it. There are many theories that explain why the pipes hum. In practice, plumbers identify four main reasons that cause this phenomenon.

Bad or poorly made repairs

Finding out why the tap is droning when turning on the water, it is first of all necessary to remember if you have had any repairs to the sanitary equipment. If the answer is negative, and the noise repeats, you need to find out if one of the neighbors has recently carried out some work. In addition, you can call the service organization (utilities), perhaps, plumbing, working in the basement, poorly performed the connection of elements.

If you found out that such actions took place, then this could well be the reason why the tap is buzzing when the water is turned on. However, everything is fixable. Eliminate the buzz will not be difficult. Badly fastened pipes are fixed, and the hum instantly passes. However, this may not be the case only. If inexperienced plumbers have placed the pipes very close, then inevitably there will be a vibration. In this case, there is nothing left but to wrap each of them with foam insulation.

Excessive pressure in the system

And we continue to talk about why the tap is buzzing when the water is turned on. One of the reasons may be overpressure. You can determine it by the head of the water, it is usually very good, and when the crane is fully opened, the jet rips out with noise and hiss. There is another way to carry out the diagnosis. Buzzing can occur if you quickly open the tap. In this case, you need to take the time to this problem, and even better to call the plumber, so that he assesses the situation.

Why is this phenomenon dangerous? The fact that it can lead to depressurization of the system. And you can not lower the pressure yourself, so you'll have to come up with something else. To reduce the load, you will need to install an air chamber. It is she who will dissipate the pressure, as a result of which the hum will cease, and you will be able to breathe freely.

Exceeding the upper limit of the norm

Since it is not always easy to understand why a tap is buzzing, it's best to ask for help from professionals. For plumbing is a routine job, it will quickly assess the situation and find the right solution. Sometimes it can be powerless and advise you to contact the water service provider. If water enters the system under high pressure, you can not do anything with a buzz yourself.

Here the logical question is: what is the normal water pressure in the system? Usually this figure is 2 atm. This indicator is optimal for the operation of a washing machine or dishwasher. However, the upper limit is 6 atm. In this case, you need to deal with the service provider right up to finding the optimal solution.

Independent installation of the air chamber

Let's continue to consider cases when we are able to improve the situation. First of all, you need to decide why the tap is droning when the water is turned on. The reasons can still lie in excess pressure, but if the indicators do not exceed the critical level of 6 atm, then you can make your own adjustments.

To do this, you only need to make a camera yourself. For this it is necessary to use an additional section of the pipe. The second option is even more preferable is the use of a factory silencer. After installing such an element, the pipes will experience less load and will last much longer.

Clogging of pipes

If your house, and, accordingly, and the plumbing equipment is 10 years old or more, it is no longer surprising that the hot water tap is buzzing. The reasons for this are simple - it reduces the diameter of the pipes due to the banal clog, which leads to vibration, and it - to the appearance of noise. It is very well transmitted through pipes, and it is usually heard not only in one apartment, but also throughout the riser.

First, you need to diagnose and determine if you really have clogged pipes. To do this, you need to detach the mixer from the pipe and carefully inspect it. The accumulated mud on the walls brightly demonstrates the overgrowth of the hole. This may be one of the reasons why the tap is droning. The instruction how to eliminate blockage is as follows.

Most often, the dirt is not deposited in the middle, namely at the ends of the pipeline. Therefore, they can be tried on their own. I would like to note one more thing: the problem of clogging is typical for propylene, as well as plastic sanitary products. This contributes to the deposition of dirt in certain places, the fact that the diameter of the hoses of the mixer is usually different from the size of the pipes themselves.

Ways to eliminate blockage

You are mistaken if you think that it is worth pouring into the system some unique liquid like "Mole", and the problem will be solved. I'll have to work on my own. Clog can be eliminated in three ways:

• Hydraulic flushing.
• Pneumatic flushing.
• Mechanical cleaning.

Let's first consider the washing option. This is the flow of water. To do this, it is not enough just to connect the hose, so use electric, sufficiently powerful pumps. However, in this way it is possible to eliminate blockages only in pipes of small diameter. This method is not suitable for thick products. In this case, heavy particles will still have time to settle on the walls.

How is mechanical cleaning performed?

This option is acceptable only if clog has appeared on separate sections of pipes. For this, water must be switched off. This is the first condition that must be met before any repair work begins. The detached pipe is cleaned with a thick wire, and for better effect, a ruff is attached to it. If it is not possible to clean the hole (deposits on the walls are petrified and become part of the system), then this section is cut out and replaced with a new one. And in order to avoid further problems, it is necessary to tightly fasten all the elements using sealed rubber gaskets. Note that even when disassembling the design, remember the location of all the elements.

Malfunction of the mixer

This can also be one of the reasons why the tap starts to hum while turning on the water. It should be noted that this is the most simple malfunction, which is eliminated in a matter of minutes. Diagnosis can be done on your own, open the tap and observe. If the pipe starts to vibrate, then either the faulty mixer or the shut-off valve is to blame. To solve this problem, it is necessary to turn off the water on the riser and proceed to a simple repair.

Most often in this case, the cause is simply a worn gasket. Remove the tap and inspect it carefully (the gasket at the end of the rod is located). If it takes a sharp form, it is necessary to make a replacement. After that, we collect the construction and put it in place. After such a procedure, the noise should disappear. We add that this applies only to old mixers, which are equipped with crane-boxes. If you have a modern single-lever or ball valve, then look for the cause in the other. In these designs, the gasket that blocks the water flow is simply not there, so it can not cause noise in the pipes. By the way, if you still decided to disassemble the faucet, you can immediately change the mixer to a more modern one.

Instead of concluding

We have considered the most common reasons why it makes noise, buzzes, whistles. Now you can do it yourself, without the help of plumbers, to make simple repairs and eliminate the annoying source of noise. It is not worthwhile to ignore such a symptom for a long time, because, besides an irritating factor, it signals that the water supply system has malfunctions, and if not taken, they can lead to more serious consequences. Therefore, without delay, carry out the necessary diagnostics, and if necessary, then call plumbers.
