PEX pressure testing

[msweeney52]

What is the best way to test newly installed PEX plumbing for the DIY er?

The usual is to turn on the water, and look for leaks.
Well or city water (doesn't matter that much).

Air pressure testing is for when water is not usable.

I am not a plumber.

Air volume changes quite a lot with temperature change so water is probably more reliable.

Unless you damaged the tubing and followed the proper technique for fittings, filling with water and a through visual check after a delay should be all you need.
