While we are on the subject of PEX. There are 3 different type of PEX A, B, & C. They have different fitting and means of fastening the fittings. Type A you install a special collar and with a special tooI you expand the pipe with the collar on it, then quickly install the fitting before the pipe shrinks. B & C you slide a ring on the pipe, install the fitting, then crimp or clamp the ring or you can use a shark bite fittings. PEX A is said to be more freeze resistant. I use to never see PEX A at Home Depot and always had to go to a plumbing supply. I am now seeing it at some Home Depots. Home Depot seem to be doing a good job of keeping the pipe and fitting in different sections.
