Once the vehicle has fully shut down the drain current reading can be gained from the multimeter. If the multimeter has been removed during the wait period, connect the multimeter to the WCDT then switch the fuse switch to OUT.

A drain test kit is used in construction to test the proper functioning of a building's drainage system. After water is filled to the top of the manhole benching, it should be left to soak for 5 minutes before begin topped up. It should be left to charge for 10 minutes more, before topping up again once the changes have been recorded. We’ve highlighted the values of leakage over a 10 minute period in our lovely table below.

Water testing, also known as water drop testing, is a method of testing drains which requires less pressure but, unlike the air test, may take up to 2 hours to set up. The test itself works through bunging up the two ends of a system, charging the system with water and overseeing the water levels either at a manhole or access point. No additional pressure should be applied when performing the water test. This means that the water level should be limited to 1.5 meters from the lowest invert level of the drain being tested. This method has the positive of being able to test a whole system at once which can be beneficial for everyone involved in the process. Drain testing procedure for a water test. Surprisingly new vehicles are susceptible to engine start issues from Parasitic Current Drain. The power demand from the vehicle battery has increased in direct proportion to the technology now installed in high-specification vehicles. During this shutdown wait period the fuse switch can be switched to IN and the multimeter can be removed to carry out other tasks. Remember to reconnect the multimeter before switching the fuse to OUT to prevent waking the car up when reconnecting.

Before attempting to fit the bungs for pressure testing ensure there are no issues or dirt that could prevent the installation and function of the bung, as any grit or dirt within the seal could allow leaking and thus fail a test.Officially, smoke testing would not count as a genuine examination of a drainage system’s ability to function correctly in terms of water tightness. However it is useful to use with uPVC piping to establish leaks and other faults that may not have shown up during a water or air test.
