Just renovated house, no water, water meters will turn? What's the reason?
In life, sometimes this phenomenon occurs: do not use water meters, "water meter idling" phenomenon. This is because the pipeline pressure causes changes in air temperature and mixed with water, memory air, pulsation and its effect to make installation in some position of water will slowly take the word phenomenon in no water, and the number is often accumulated increasing.
The water pipes are empty, the air will "take advantage of a weak point; when the recovery water, the water pipe of the air pressure to the indoor pipeline all the blind end, the formation of" compressed air ", until the air pressure and water pressure balance so far. There is an interface between gas and water, when the pressure difference between the two sides of the interface is zero; and when the water pressure changes, the two sides of the interface form a certain pressure difference, and the gas and water balance is destroyed. To compensate for this pressure difference, to reach a new equilibrium, must change the pressure of the air, causing air volume expansion or contraction, thereby causing the pipeline "connector" in tap water flow, so the "idling" phenomenon is produced.
To solve the "water meter idling" problem, first of all, to open all the taps within the user, remove the air inside the faucet, and then check the indoor pipes are leaking, especially the toilet, shower and so on. If the problem cannot be solved at this point, find the blind end of the pipe. Be patient to examine whether there are changes of indoor pipeline, especially the kitchen and the bathroom has not changed in the transformation of the place, looking carefully plug pipe blind end "(sometimes more than one), the next step is: (1) water before the valve closed, with pliers and unscrew the plug"; (2) to open the valve, let the water to discharge the air in the tube; (3)) off a small valve, until the water slowly from the mouth overflow, overflow in the cover of "plug", slowly tighten; (4) to open the valve, normal water. In short, if we carefully once found "idling" phenomenon, unless water meter and pipeline fault Water Leakage, almost certainly "idling" phenomenon is caused by the air in the pipeline, the key is to find the blind end of the "plug" of this "source" from the start to solve this problem.
