How to test drain pipes |

4/2/2019· A drain pipe test ensures the pipe is sufficiently watertight. This prevents the pipe from leaking its contents into the surrounding soil and potentially overloading or contaminating the local water table. When laying new pipes, it is essential to test them before the trenches in which they are laid
