Amazing pressure on a closed system. Still, I cannot stand letting water run which would solve the issue but oh my the price. Outside I have had good luck with galvanized pipe when frozen. What did you do?I installed double insulated PVC pipe for automatic waterers in my horse barn in high desert area of central Cal.... one night ALL of the PVC lines split the long way up to 12 feet long. The only reason that there was no flood was because water in the lines formed to ICE at 14* F . Even a couple of the copper lines burst going to the barn and inside our home too !
