I have only found a wholesale supply company that has then, but won’t sell to me. I was hoping somewhere on the web would have them. 4 Sep 2001 at 11:45 pm #291526 SylvanLMPParticipant Normally to test a “DWV” piping systems you use potable at a height of 10 feet. This will give you almost 5 PSI Then you wait about an hour to make sure no leaks occur. Other piping systems vary as to pressure testing but most localities will go the for 10 ft head Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
