A. How to detect a water pipe leak at home

Free hands-on teaching you how to detect whether the water pipe leaks, and teach you how to detect the hot water pipe leaks? or cold water pipe leakage, conventional detection instruments are generally water and steam dual-use pressure pump, in addition to the instrument, can no longer find better than this instrument, the tutorial provided by the Youjiu waterproofing, the specific detection methods are as follows.

1, tool preparation


Water and steam dual-use pressure pump, pliers, active wrench

2, close the water valve

Before testing, the first manual type pressure pump filled with water, and then close all the water mains switch, especially the cold water pipe and hot water pipe into the main valve, in addition to the toilet, squatting pit, bath, balcony, washbasin, etc. ...... All triangle valves or faucets are all closed.

Note: regardless of the home installation is a water heater, instantaneous water heater, solar energy, water purifier, etc., before testing the tap water pipe, please be sure to ensure that the water heater, instantaneous water heater, solar energy, water purifier, etc., the inlet and outlet valves are closed, otherwise in the detection process, due to excessive pressure, the water heater, instantaneous water heater, solar energy, water purifier, etc. will be broken, if there is no switch or triangle valve, it can not be detected, even if it can detection, the accuracy is not accurate enough.

3、Start detection

Connect the manual type pressure pump tube with the triangle valve, and twist the screw, then open the triangle valve, then open the main water valve of the water main, and then close the main valve.

At this time, observe the manual pressure pump pressure gauge is how much, if its own pressure is 0.2, then the pressure process, you can properly pressurize to between 1.0 ~ 1.2, more than 1.5 ~ 2.0.

To be fully pressurized to 1.0 ~ 1.2, you can observe 5 ~ 10 minutes, if the pressure gauge falls to 0.5 ~ 0.8 between completely immobile, it proves that the water pipe does not leak, if the pressure gauge falls to the above figure a 0.2 ~ 0, it is full proof that the water pipe leak.

To the right side of the cold water pipe detection is complete, you can test the left side of the hot water pipe, detection method and the right side of the cold water pipe, to be detected clearly is the water pipe leak, to confirm the leak after the use of Puch pipe leak detector to find out the leak point.


Generally speaking, the basic detection method is, connect the pipe leak detector host, headphones, sensors. Turn on the switch, put on the headset, place the sensor on the road above the pipe line, place it step by step according to the length of the pace, and listen step by step, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting the leak. Therefore, we use the pipeline leak detector, a single point in the leak signal is not meaningful, to repeatedly compare multiple points, compare the sound vibration of the larger place is the leak, of course, we have to consider many other additional factors, such as the direction of the leak breakage mouth, because the pipe is round, if the side of the leak, the larger point may instead be on the side of the road above the pipe, rather than The road above the pipeline, so the location of the pipeline to know, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact on the detection to take these into account.
