So I had the gas line disconected last year and now to get it back on - o need a permit, pressure test - ect.. so I was going to mount a gauge and stick an air fitting on it - anyone know how much pressure they would want to test with? Natural gas is what 5-10psi so would 100 make them happy?
Requirement is three times operating pressure. Since in home gas lines are .5PSI, three times that will suffice. Most of us just go ahead and test them to 5 psi. Gauge needs to read in tenths and the test should hold steady for at least 15 minutes, or until the inspector is happy. Getting 5 psi to hold on gas lines is harder than you think. First place to check for leaks is the valves. Always cap the lines after the valves. Don't trust that they will actually completely hold the pressure. The tiniest little leak will show a pressure drop.
Just got off the phone - they want to see 40psi held for 24hrs.. insane... my system is small , I have 8 joints and 7 feet of blackpipe so it should not be that bad but they are coming out next week to stick a gauge on it than inspect it 24hrs.
I sell flex hoses for the propane storage plants.
They require the hoses to meet a 350psi WP with a 1,750psi burst factor.
Knowing my coworkers I sometimes get nervous.....JK

in some parts of the trailer park there are probably people who would install a shrader valve in a hidden location so they can pump it up before the inspector returns...
