Abstract:
A method for pressure testing a branch circuit of polyethylene pipe that is connected to a main line with a tapping tee fitting comprising:removing the cap of said tapping tee; adjusting the position of the hole cutter inside said tapping tee to a depth at least approximately equal to the diameter of said hole cutter; installing a pressure test adapter to said tapping tee, said adapter being adapted to engage the internal threads of said tapping tee, said internal threads being the threads in which said hole cutter is engaged, said adapter having an o-ring seal, said o-ring seal being adapted to seal against the surface of said tapping tee that is perpendicular to said internal threads, said adapter having a valve and a pressure gage; applying a pressure source to said valve to pressurize said tapping tee; indicating a pressure on said pressure gage; removing said pressure from said valve, said valve being engaged to hold said pressure inside of said tapping tee; and ensuring that said pressure is maintained within a predetermined limit for a predetermined time.
