Continue to understand how the noise in the water pipe is going. The master of water and electricity said that it is called the water hammer effect. If the water hammer absorber is broken, open the faucet or open the water to bathe upstairs, the air will enter the water pressure and the pressure cannot be released. The bigger the noise, the bigger the noise. If you want to improve, experts suggest that you can change a water hammer absorber or change to a variable frequency motor to reduce noise interference.   The faucet is turned on, the sound of water is loud, but listen carefully, there is a sound, the sound of air hitting the water pipe, in addition to the sink and the bathroom, open the shower head to flush, you may also encounter this noise, which has caused a lot People's troubles. People: "Sometimes you may be noisy upstairs or downstairs when you sleep. Water hammer effect, it seems that there is a sound on the top floor, I heard." Sure enough, many people were disturbed by the sound of water, and they couldn't even sleep well at night.   ▼ The master of hydropower said that there was too much air in it, and the high-pressure shock could not be released. (Picture / Dongsen News)   Mr. Su, a master of hydropower: "The sound of (running) running, the whole pipeline can be heard, the stronger the pipe, the louder the water hammer."   Dongzi News reporter Wu Ziyi: "The sound of water will become noise. It is very likely that the water hammer absorber is not installed or the water hammer absorber is broken. Like the faucet in this house, we will have this sound as soon as we turn it on. There is another kind of sound. The sound of ticking from the water pipe is commonly known as the water hammer effect. In addition to noise, excessive water pressure can cause the water pipe to burst. "   Generally, an apartment or building will be equipped with two water hammer absorbers and a silent check valve. Open the faucet or take a bath upstairs, and the water will be pumped upward. The air will enter the house through the pipeline. The absorber is vented, so the chance of it being broken directly below is relatively high. If it is broken, the air in the water pipe will be more and more, and the high pressure cannot be discharged, and noise will occur.   Mr. Su, a master of hydropower, said: "The motor water control system is replaced by a frequency conversion type. The frequency conversion allows the motor to slowly spin up and then draw water. When it stops, it also gradually lowers the pressure."   When the faucet is turned on, the noise caused by the water hammer effect causes many residents to have disputes with their neighbors. For example, in January 2015, Taipei ruled that the homeowner turned on the water heater, and the hot water pipe made a loud noise due to the water hammer phenomenon. Neighbors reported that the homeowner was sentenced to pay 190,500 yuan according to civil law, and that water must be used at any time. If there is a strange sound in the pipeline, be careful, in addition to disturbing the people, it may also lead to lawsuits.
