To make a pressure tester for you're roughed in Plumbing you will need 1-1/2" Sch. 40 "T". Glue a MPT adapter and a short piece of 1-1/2" pipe in the bottom port then Glue a 1-½" slip x ¼" MPT bushing in the "T" port and place a 0 to 60# pressure gauge in that bushing. Glue a 1-½" slip x ½" MPT bushing in the top port and put a ½" boiler drain valve in that bushing. You will need to use a automatic washer hose that has a female water hose fitting on both ends to connect to the garden hose. Use a short piece of rubber hose double clamped with the adjusting screws both facing you (by being opposite each other you will have a good seal) to connect to and check each underground plumbing line.
