Why are water pipes buzzing
Often, tenants of apartment buildings face the humming of water pipes. This acoustic noise is usually heard throughout the riser. Where and why does it come from? Is there any way to fix it? In this article, you will learn why water pipes are buzzing in an apartment and a private house, as well as how to eliminate noise.
Causes of buzz
The most common causes of jingle are:
- Poor repair. Гул в квартире нередко связан с неплотным соединением труб или некачественным их монтажом.
- Excessively high pressure in the water supply. The noise increases after turning off the water in the tap. This acoustic effect can be associated with repair work on the track. In this case, only the management organization can resolve the problem.
- Reducing the internal diameter of the pipe. If in a private house for a long time did not carry out repairs of engineering communications, then such a phenomenon as noise is quite explicable. Over time, the pipelines are overgrown with rust and salt, as a result of which their diameter decreases. With all this, the water pressure remains the same, which provokes noise.
- Plumbing faults. Noise can be triggered by malfunctions of taps and mixers. It can be a broken cock axle box and incorrectly installed or selected gaskets. In this situation, the noise will be heard in all apartments on the riser. To identify the problem, it is necessary to consistently disable the opening valves in each apartment on the riser.
Consider each problem in more detail.
Poor repair
If the buzz is heard when opening the tap several times a day, then it is very likely that someone in the neighborhood repaired the water supply recently. It is even possible that plumbing repair specialists would replace pipes in the basement. Some kind of mistake was made in their work. For example, connections are made unreliable. In this case, leveling the unpleasant buzz is very simple. For this purpose, all installation errors are eliminated.
Another reason for the noise from the plumbing is that the pipes are mounted close to each other. The thing is that when the water passes through the pipeline, a vibration is created, as a result of which the pipes buzz together. To eliminate noise, simply wrap each pipe in foam insulation.
High internal pressure
The pressure force is easily determined by the pressure of the water. If you quickly open the taps, then with an overpressure the pipes are buzzing. Excessively high pressure over time will lead to rupture of pipe joints, and as a consequence, to the depressurization of the water supply system.
To reduce the load on the pipeline and eliminate noise, install a valve at the junction with an air chamber that will take on the excess water pressure.
Such a camera can make yourself. To do this, take an extra piece of pipe or a special factory silencer. Thus, the load on the pipeline will be significantly reduced and it will last much longer.
If you are unsure that you can do everything yourself, then seek qualified help. In addition, if the water pressure is excessive due to the admixture of air in it, then you will not be able to cope with the problem yourself.
Normal is the pressure of water with a pressure in the mixer - 2 atm. In this case, a dishwasher and a washing machine will work. The limiting limit can be considered the pressure value equal to 6 atm.
Reducing the internal diameter of pipes
Due to the reduction in the diameter of the pipes, a reactive water flow is formed from inside, creating vibrations, which are responsible for the hum. How in this case to diagnose? To do this, you must inspect the mixer, after disconnecting it. If you see dirt on the walls, then this is a sign of the overgrowth of the entire system. The impurities in the water are gradually deposited on the end sections of the pipe systems. This means that you can still clean them.
Such clogs occur not only in the steel pipeline, but also in polypropylene, plastic. This is due to the fact that the diameter of the pipe and mixer hoses are different, and this, as a result, leads to the formation of plaque.
Such blockages can be eliminated using pneumatic or hydraulic flushing. As a less effective option, mechanical cleaning can also be used.
Flushing is the flow of a continuous, strong stream of water through the water supply system. Circulation and electric pumps are used for flushing. However, it is worth noting that this technique is ineffective when it comes to flushing large diameter pipes. In this case, flushing of individual sections of the pipeline. Water from them goes down, the pipe is disconnected, after which the specialist cleans the inner walls with a thick wire with a brush at the end.
If it is impossible to remove the blockage, the problem area should be disconnected from the common pipeline and replaced with a new one. Installation of a new pipe is performed using special sealing rubber.
Plumbing faults
Rattling in the pipeline may be caused by faults in the water fittings. To eliminate the problem, turn off the water in the riser and carry out repairs. A malfunction in the mixer is also often the cause of a hum. This may be elementary - worn gasket on the crane of the old sample. The solution is not less banal - to replace the gasket and install the crane in place. If the repair was carried out correctly, then you will no longer hear the noise.
Malfunctions in the work of the crane of the axleboxes and the characteristic noise for them occurs only when the half-turn or valve-type axle box of the old model fails.
In single lever mixers and ball valves there are no gaskets that block the flow of water. And, therefore, they in their structure can not create a hum.
