air pressure testing new PEX system
i ave finally go to the pressure stage. 2 shower connections and one hose bib have only end plugs, otherwise all angle stops are in so are in the test. i have pressured up to 70 psi (funny, i took the air off at 65 psi and it climbed to 71, i assume the pex expanded a little then recovered?)
how long should i let it stand? i have heard 2 hours and 24 hours both.
is 70 psi enough? i have heard 60 is cool, and also heard to take it to 100. just seems scary but if its rated for much higher then it should be ok, just makes me nervous
