plumbing air pressure test
I am adding a walk-in shower with rainshower head mounted from ceiling, 4 body sprays mounted in the wall, a handheld body wand, an exact temp control valve, and 3 volume control valves . I have 3/4" pex supply lines to temp valve, then 1/2" copper to control valves,then 1/2" pex to respective sprays. I have capped everything, and applied an air gauge. I placed 85 psi of air. In a period of appx. 40 hours, the pressure has dropped to 75 psi. Does this indicate a leak, or is this an acceptable loss attributed to tempature fluctuation or some other variable? What is generaly accepted as a succesful test?(time/pressure) ------------------------------------- ##-----------------------------------------------## Delivered via http://www.thestuccocompany.com/ Building Construction and Maintenance Forum Web and RSS access to your favorite newsgroup - alt.home.repair - 330455 messages and counting! ##-----------------------------------------------## |
