Why does the water pipe buzz when the faucet is turned on

The faucet sometimes buzzes when it is not turned off, and even the water pipes are a little shaky because of the water hammer effect inside the water pipes.

The water hammer effect is a figurative statement. It refers to a kind of severe water hammer produced by the water flow hitting the pipe when the feed pump is started and stopped. Since it is inside the water pipe, the inner wall of the pipe is smooth and the water flows freely.

When an open valve is suddenly closed or the feed pump is stopped, the water flow will create a pressure on the valve and pipe wall, mainly the valve or pump. Due to the smooth pipe wall, the subsequent water flow under the action of inertia, the hydraulic force quickly reaches the maximum, and produces a destructive effect, which is the "water hammer effect" in hydraulics, that is, positive water hammer. Conversely, a closed valve can also produce water hammer after it is suddenly opened or the feed pump is activated, which is called negative water hammer, but not as large as the former.

The instantaneous pressure generated by water hammer can be tens or even hundreds of times the normal working pressure in the pipeline. Such large pressure fluctuations can cause strong vibrations or noises in the piping system and can damage valve joints. It has a great destructive effect on the piping system.

In order to prevent water hammer, it is necessary to correctly design the pipeline system and prevent the flow rate from being too high, and the general design pipe flow rate should be less than 3m s, and the opening and closing speed of the valve should be controlled.

The speed of the water changes sharply due to the rapid opening and closing of the pump, especially the water hammer caused by the sudden stop of the pump, which can destroy the pipeline, pump and valve, and cause the pump to reverse and reduce the pressure of the pipe network. The water hammer effect is extremely destructive: too much pressure can cause the pipe to rupture, and conversely, too low pressure can cause the pipe to collapse and damage valves and fixtures.

In a very short period of time, the flow of water goes from zero to nominal flow. Due to the kinetic energy and a certain degree of compressibility of the fluid, a large change in the flow rate in a very short period of time will cause an impact of too much pressure and too low pressure on the pipe. The pressure shock will cause the pipe wall to be stressed and produce noise, just like a hammer hitting the pipe, so it is called the water hammer effect.

Proof that the inside of your faucet is not well sealed (presumably there is something wrong with the rubber ring inside).

Because the seal is not tight, the water flows out of the gap, causing vibrations and then noise.

The faucet is always buzzing Solution:

Method 1: Install a blind pipe at the highest point of the water pipe, with a faucet, and discharge the air regularly; The air floats upwards and the water flows downward.

Method 2: Turn the faucet on a bit appropriately and catch the water with a basin to prevent waste, which will eliminate the hum. There will just be a slight dripping sound.

Method 3: Just replace the faucet with a new one.

The faucet is a popular name for the water valve, which is used to control the size of the water flow and has the effect of saving water. The replacement speed of faucets is very fast, from the old-fashioned cast iron process to the electroplating knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel dual-temperature double-control faucet, kitchen semi-automatic faucet. Nowadays, more and more consumers will consider the material, function, shape and other aspects of faucets.

The reason why the faucet is buzzing and leaking:

The faucet does not come out of the water smoothly, and the shock wave is generated, and the frequency of the shock wave is the same as the resonance frequency of the pipe, causing the pipe to resonate and make a sound.

The lack of pressure in the faucet pipe causes the sound of water in the water pipe flowing backwards.

You can see if the noise of the faucet is caused by the wrong size of the faucet gasket or if the gasket does not fit snugly on the faucet core. If this is the case, the noise can be eliminated by replacing it with a new gasket or by fitting it snugly.

Workaround:

Drain the air from the faucet pipes.

Precautions: 1. Don't use too much force to turn the faucet on and off, just turn it gently. Even a traditional faucet doesn't require a lot of effort to wring it to death. In particular, do not use the handle as a handrail to support or use.

2. The metal hose of the shower head of the bathtub faucet should be kept in a natural stretching state, and it should not be coiled on the faucet when not in use. At the same time, when using or not in use, pay attention to the joint between the hose and the valve body to avoid breaking or damaging the hose.

3. Under the condition that the water pressure is not lower than that, after a period of use, if it is found that the water output decreases, or even the water heater goes out, you can gently unscrew the screen cover at the water outlet of the faucet to remove impurities, and it can generally be restored as before.

4. Experienced and qualified professionals should be invited to carry out construction and installation. When installing, the faucet should try not to bump with hard objects, and do not judge where to leave cement, glue, etc. on the surface, so as not to damage the surface of the surface plating gloss. Pay attention to remove the debris in the pipe and install the faucet.

Summary. The rubber pad in the faucet is aging, and it is OK to replace one, because the pressure of the water in the water pipe is very high, and when the faucet is closed, it is closed too quickly and too violently, resulting in a partial vacuum of water hammer caused by the water pipe. You can turn the faucet back on when it makes another noise, and then slowly close the faucet so that it doesn't make a screeching sound of water hammer.

When I turn on the faucet downstairs, my water pipe is buzzing and vibrating badly, what is the reason and how to solve it?

Hello, dear, I am very happy to answer for you.

The rubber pad in the faucet is aging, and it is OK to replace one, because the pressure of the water in the water pipe is very high, and when the faucet is closed, it is closed too quickly and too violently, resulting in a partial vacuum of water hammer caused by the water pipe. You can turn the faucet back on when it makes another noise, and then slowly close the faucet so that it doesn't make a screeching sound of water hammer.

The faucet may be broken due to high pipe pressure, and you will be fine if you replace the quick-opening faucet!

As an indispensable product in every home, the faucet is a good water control device. Basically, no family can do without it. The faucet categories on the market can be said to be varied, and we still have to consider it more when we buy.

Let's introduce to you how to solve the buzzing of the faucet.

How to solve the buzzing of the faucet.

1. If there is a problem with the faucet, replace the faucet with a new one, and the sound will disappear; 2. If it is not a problem with the faucet, it is likely that there is air in the water pipe or the water pressure is not stable.

How to choose a faucet.

1. Look at the structure of fierce pins.

The first element of choosing a faucet is to look at its structure, as a multi-category product, we can decide according to our own preferences or needs when choosing. According to its structure, the faucet is divided into single handle, 90° switch, etc., which are more practical types, as long as they are determined according to our needs.

2. Look at the surface coating.

For the surface coating, we also have to do our homework, not all faucets are the same surface, the difference is still very big. Among the many surface coating varieties, we should consider our own preferences and whether they match the whole. It is recommended to choose products with excellent manufacturing technology, some products that look a little bright, if it is with bright chromium on the surface, the quality is more reliable, because this process technology is very mature.

3. Look at the quality.

When purchasing, we also have to check the handle of the faucet, whether it is light and flexible to move, and there will be no sense of jamming, if not, it means that there is a quality problem with this faucet. Also, if it does not fit under the standard size, it means that the quality is not good, so you must choose products with good quality, and it is recommended to buy big brand products.

A buzzing faucet can be caused by things like high water pressure or aging water pipes. It can be solved by adjusting the water pressure or replacing the zero locust height piece inside the wide faucet. The specific method is to check whether the water lead ruler pressure is too high, if it is too high, you need to adjust the water meter or install a pressure reducing valve; If the water pressure is normal, parts such as gaskets or filters on the inside of the faucet need to be replaced.

Hello dear<> The water pipe is buzzing when the water is released. The solution is as follows: 1. The buzzing sound when the water pipe is discharged is that the pipeline is not installed firmly, the water pressure in the water pipe is too large, and the valve core produces self-excitation oscillation, so the water inlet valve can be closed a little smaller. 2. The buzzing sound of the water pipe when the water is released is that the sealing parts of the faucet are damaged, and the water rushes out from the gap to cause vibration, and then produces a sound, so it is recommended to replace the faucet.

3. If there is a problem of water leakage in the water pipe, it will make a buzzing sound. Especially in some public drainage pipes, if there is a leak, it is most likely to make noise, so it is enough to solve the problem of water leakage. 4. If there is air inside the pipeline, there will be a humming sound when the pressure is uneven, and an automatic exhaust valve can be installed at the highest part of the pipeline to eliminate the sound.
