I've got my waterlines for a full bath all set up all the way except to connect into the water sources and capped all ends. I placed my air pressure gauge on the hot water line where it will eventually connect to the hot water pipe. My cold water line has a male threaded adapter at the end to test that line. It is not currently capped. When I fill the hot water line with air pressure Air escapes through the male threaded adapter on the cold water line. 1st is this normal? I'm assuming that the air is escaping through the shower valve since that's the only place where the hot water and cold water lines intersect, but that doesn't seem normal, is it?
Thanks
