How to Find a Water Leak in your Home

    Water leaks in your home can amp up the bills, damage the structure of your property and encourage the growth of mold. To stop the damage, you need to stop the leak. However, it sometimes takes more effort to find the leak than to repair it.

    Hot Water Tanks

    Check the hot water tanks, especially the pressure relief valve on it. In most cases, these valves are connected to the drain and might be leaking. The best way to check it is to check the drain pipe thoroughly. However, if you can’t check this pipe, you need to pay close attention to any unusual hissing sound coming from it. If you hear that sound, there’s definitely a leak in the pipe.


    Leakage in toilets is also less obvious and difficult to spot. To check here, you need to remove the lid of the tank and listen carefully. If you hear the same hissing sound, it’s very likely that there’s a leak in the tank. Try to locate it and see if you can fix the problem.

    However, if you can’t find the leak, add a few drops of food coloring in the tank. Wait for a few moments to see if the water in the toilet bowl changes color. If it does, there’s a leak in the flapper, which is located at the bottom of your tank. The flapper might be letting the water through.

    The Meter Line

    If you don’t find the leak in the toilets, check the meter line. First, you need to shut off the water supply valve that’s located by your house. This would temporarily stop water supply to your home.

    Once the valve is shut, check to see if the meter is still running. You’ll need to find the meter, remove the lid and check the dial. If the meter stops turning and even after watching for a couple of minutes, if there’s no activity on the dial, the leak is inside your home.

    However, if the dial is turning after shutting the valve off, then the leak may lie between the meter and the valve. In that case, investigate along the pipe, looking for muddy, moist areas, greener grass, etc. Dig the area and check the pipe underneath. If it’s damaged, you need to replace it.

    If the problem isn’t in the meter line, check for leakage in hose-bibs, showerheads or even swimming pools. You’ll save some money on repairs if you locate the leak, point it out to the plumber and get it fixed on time.
