My Panther Building Documentation at PantherBuilder Web Site Daniel R. Heath -?Lexington, SC -----Original Message----- To pressure test a tank you use a pressure gauge connected to a T fitting screwed in to the tank. One of the T connections to the tank Another to the pressure gauge The third to the valve Open the valve to allow air to go in to the tank Close the valve and make sure the pressure doesnt drop after a set time say 24 hours. Open valve to vent the tank and then unscrew the T.
