Buried pipes are just a pipeline installation measure that hides the pipes underground, this method is good for the overall aesthetic effect, but once a leak occurs it is more difficult to deal with. Today, Rambi Xiaobian will share with you how to find the leak of buried pipes and the method of bathroom drainage buried pipes, I hope it will help you.
1, the method of observing the water meter at night: late at night when no one is using water, observe whether the water meter pointer rotation, if the water meter pointer continuous rotation non-stop, then there is a leak in the pipe. Water leak detector
2、Water balance test method: Calculate the water consumption of each branch separately, and the difference between the water consumption of each branch and the sum of the water paid should not be greater than 15%, if it is greater than 15%, it means that there is water leakage in the pipeline. The water consumption of each branch is mainly accounted for by the sub-water meter, and the installation of the sub-water meter is the basic work to reduce the loss of the water supply system.
A rough judgment based on per capita water use experience. Statistics show that the average person consumes 100 liters of tap water per day in urban areas in northern China and 180 liters per day in urban areas in the south; then other water uses such as production, public sanitation, green water, etc. are added, i.e. the actual water use is roughly determined and compared to the amount of water paid for (1000 liters = 1 cubic meter). For any unit, this is a very necessary and critical step. Many units do not do this and are unable to detect leaks in their pipes in a timely manner, so they pay more for water than they should over a period of years.
3. Based on the monthly water usage analysis, if you exclude temperature changes and a sudden increase in water usage, there must be a leak. Usually there is a hidden leak in the water pipe, equivalent to a faucet being open 24 hours a day, and the water volume will be abnormally high, with peaks exceeding 20% or even several times the original.
4, according to the water pressure judgment. Water pressure is lower than before, the original location can be on the water, later it can not be on the water, most likely due to a dark leak in the pipeline.
How to find out the pipeline leakage point
Using Puch pipe leak detector can effectively find out the leak point, and its working principle is that when pressure water is rushed out from the broken mouth of the pipe after the pressure water pipe leak, the sound vibration generated by friction with the pipe wall and other additional vibration caused is transmitted above the ground of the pipe, and the leak point is found out by using the instrument to detect on the road.
In general, 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 pipeline, place it step by step according to the length of the pace, and listen to it 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.
