Buzzing in water pipes is familiar to many tenants of apartment buildings. It seems that nobody in our apartment did anything, did not open the cranes, and suddenly there is a buzz that comes from somewhere. Let's try to understand the causes and methods of "fighting" with this noise. This phenomenon refers to the field of hydraulics. A professional theorist can name dozens of reasons that cause such a rumble. However, practice shows that for us, we can identify the main four, the most common, we will stop at them.
Poor repair
If the rumble in the faucets appears daily, and several times a day, then it should be asked which of the neighbors did the repair of the water system( or its elements) in his apartment. Perhaps, and the locksmith of the service organization changed something in the basement( on the ground floor).Such hum can be caused by a loose connection of pipes or by their unreliable installation. It is not possible to eliminate such a "malfunction" of labor.
Overpressure in the
system It can be determined by tap water pressure in the tap. However, this is extremely rare, usually after some repair on the track. If the water pressure is too high, you need to notify the management company. If there is a rumble when the hatch is opened and the tap is closed, this confirms the "diagnosis".Increased pressure in the system can lead to its depressurization or to rupture of joints( and even the pipes themselves).As an option - to install an air chamber on the pipe - it will "take" over the excess pressure.
Reducing the internal diameter of
pipes This can be in houses where engineering communications have not been overhauled for a long time. On the inner surface of the pipes is the deposition of salts, rust. This leads to a decrease in the internal diameter, and the water pressure in the water pipe remains the same. Here is the buzz, and it will also interfere with us daily. In the apartment it is better to replace the metal pipes with plastic ones.
Defective plumbing
Specialists point out that even a single gasket in the faucet( mixer) can cause such a vibration. The first thing you need to determine the apartment, "guilty" in such a noise. It is sufficient to turn off the inlet water supply taps in each apartment in turn throughout the entire riser. And already when the apartment is determined, it will not be possible to reveal a faulty tap or a mixer of labor. Such a buzz prevents everyone, therefore it is not a problem to negotiate with all tenants about such "repairs".
