Leak Detection

DIY Water Leak Detection Test Demo


  • HI I’m Fred Marshal with Advanced Foundation Repair and I’m here today to talk to you about diy water leak detection test options.
  • A leak test does not locate leaks. It just tells you whether or not you have a leak.
  • Leak tests are normally performed after a foundation has been lifted to see if the lifting has caused any leaks.
  • To test for leaks it is first necessary to locate the sewer clean outs.
  • Normally sewer clean outs look like this.
  • You have a screw on cap or a clamped on rubber cap.
  • To test for leaks a sewer balloon such as this is pushed down into the sewer system then inflated with a pump.
  • Next the sewer is filled to the level of the pipe with water.
  • If the water level in the pipe falls after the pipe has been blocked off at the main, that means there is a leak in the sewer system.
  • Sometimes it is necessary to pull a toilet and fill the sewer from inside of the house.
  • Again if the water level falls there is a leak.
  • To test for leaking water lines a pressure gauge such as this is screwed onto a tap.
  • The house is checked to make certain there is no dripping or leaking fixtures.
  • The water is turned off at the meter.
  • If the pressure holds in the gauge then there is no leak in the system.
  • If the pressure falls, there is a leak in the system.
  • A leak test does not tell you where the leak is, only that there is a leak.
  • The next step is to have any leaks located and repaired.
  • Remember leaking sewer or water lines can cause serious damage to your foundation.
  • So get your leaks fixed.
