Detecting indoor water leaks
Detecting indoor water leaks is a meticulous process that requires a combination of methods and tools. Here are some common methods:
Observation
Walls and floors: Carefully observe the walls, ceilings, or floors for moisture, water stains, or water marks. These signs may be a clear indicator of a leak, especially at the bottom or around the walls.
Mold and odors: Watch for mold, mildew, or damp odors on the walls, ceilings, floors, or corners. These odors are often caused by moisture and mold growth.
Touch the wall: Gently touch the wall. If it feels damp or slippery, it may mean that there is moisture or water seepage in the wall.
Hygrometer
Detect humidity: Use a hygrometer to detect the humidity of the wall. If the humidity of the wall is significantly higher than the surrounding environment, there may be a leak in the wall.
Water meter method
Observe the water meter: Turn off all faucets and water dispensers and observe whether the water meter is still moving. If the water meter is moving, it means there is a leak. At this time, you can try to close the main valve and observe whether the water meter stops turning to determine the location of the leak.
Water-using appliance inspection
Check water-using appliances: Check all water-using appliances in the home, such as toilets, shower rooms, faucets, etc., for leaks. If a water-using appliance leaks, it needs to be repaired in time.
Pipeline connection inspection
Check the connection: Check whether the connection between the water pipe and the water-using appliance is leaking. If a leak is found at the connection, you can reconnect or replace the connection.
Drain pipe inspection
Check the drain pipe: Check whether the drain pipe is leaking. You can close the water valve, then open all drain outlets, and observe whether there is a leak downstairs. If the drain pipe is leaking, you need to replace or repair the drain pipe.
Pressure test
Pressure tester: Select a water outlet for testing, shake the pressure rod of the pressure tester and keep it for at least 30 minutes until the pressure exceeds about 3 times the normal value. If the pressure value drops significantly, it means that the water pipe is leaking.
Professional tools
Leak detector: Using professional leak detection tools such as moisture meter, thermal imaging camera and leak detector can help locate the location of the leak in the wall. These tools can detect indicators such as humidity, moisture penetration and temperature difference to determine the location of the leak.
Sound detection
Leak sound: You can hear the sound of dripping, flowing or leaking water from the water pipe or water source. The leak detection instrument picks up the sound of the leak and converts it into an electrical signal, which is amplified and digitally filtered to determine the exact location of the leak.
Waterproof layer inspection
Check the waterproof layer: If the above methods do not find the cause of the leak, there may be a problem with the waterproof layer. At this time, you need to ask a professional maintenance personnel to check whether the waterproof layer is damaged and re-perform waterproofing.
Regular inspection
Preventive measures: Regularly check the water pipes and water-using appliances in your home to detect and deal with potential leaks in a timely manner to avoid further damage and increased repair costs.
With the above methods, you can effectively detect and locate indoor leaks. If the problem is complex or cannot be solved by yourself, it is recommended to consult a professional plumber or plumbing expert.
