If there is a leaking in your home, try the following steps just to confirm it. Note down the water level of the overhead tank. Mark the water level in the tank and turn off the water supply main valve for a few hours to stop the water flow. If there is a difference in the water level from the marked area, then it is confirmed that there is water leakage in the pipelines. Call or hire a plumber to get help immediately to stop water wastage and water leaking from damaging the building. The plumber identifies the spot where the plumbing pipe is leaking and resolve the problem.
