How to determine whether a water pipe is leaking or seeping? What are the leak detection methods

A. How to determine whether the water pipe is leaking or seeping?

1, pipe leakage: pipe leakage refers to the leakage caused by defects such as breakage of the upper and lower water pipes, floor drains and toilet interfaces, etc. The inspection methods are

Upper pipe leakage: this situation is characterized by continuous and uninterrupted leakage, something leakage also has the phenomenon of increasing, such as closing the main valve, the amount of leakage will immediately reduce.

Downpipe leakage: first observe the amount of leakage and make records, then open all the faucets, toilets flush several times and pour water to the floor drain, then if the amount of leakage increases, it means that the pipe is broken and leaking.

2、Surface leakage: there are two ways to identify surface leakage: only under the conditions of bathing, mopping, etc., i.e., leakage occurs when there is drenching and ponding of water on the ground and walls, in which case it can be identified as surface leakage.

B. Using the method of inspection and identification of pipeline leakage to check if it is determined that it is not a pipeline leakage, that is, surface leakage. If it is a pipe seepage, can only plan the tile, change the pipe, redo the waterproofing. If it is the bathroom surface seepage, you can use the following methods to repair: surface leakage specific repair methods

1、Speaking of the surface of the dust, oil, water, etc. to deal with clean, and keep the surface dry.

2, in the entire surface can be showered, such as: tile surface, tile joints, wall joints, pipe roots and other parts, spraying penetrating waterproofing agent, do not miss spray;.

3, after the surface of the waterproofing agent dry, fill all tile joints, and broken and defective parts with waterproof paste.

4, the corners, walls, pipe roots and other weak links, with steel clay seal edge reinforcement. Note: After the end of waterproofing construction, waterproofing materials are required to dry before showering.

Water leak detection methods.

1. Collect pipe data to find the leak. Collect drawings of the pipeline and water use data. Companies arrange for technical staff familiar with the location of the pipeline to point out information about the pipeline.

2. Leak detection in the regional pipeline network environmental survey The purpose of the pipeline network environmental survey is to fully understand the site conditions and prepare for the next step in the construction arrangement and method selection for leak detection work. Including pipe network environment survey, subsidiary equipment survey, water consumption survey and drainage survey.

3. Leakage survey. In the work zone, 100% of fire hydrants, valves, water meters and clear pipes were directly listened to every day to listen to the sound waves from the leak point to the pipe structure and to find abnormal leaks. Detailed records of the number of foreign industries, location, abnormal nature, abnormalities and explanations.

4. Sound and listening to detect leaks At the top of the pipe in the survey area, the PQWT pipe leak detector was used to detect leaks, following an "S" route along the pipe at 0.5 to 1.0m intervals. This was done in a relatively stable water use and relatively quiet environment. Leakage of the pipeline buried under the road was investigated and the ground where the leak might occur was marked. Used to detect the "meter" profile in the anomaly profile. The hearing inspection rate is 100% and the abnormal sound rate is 100%. C. Detailed records of outliers and surroundings.
