[QUOTE="Oakman"]Do you have an outside shower? I seem to remember that years ago this problem was attributed to having the outside shower cold faucet open but the water flow was cut off at the shower head. The fix was to make sure the shower faucets were in the off position.
This is a good thing to check! I manage a school district and recently changed out a very expensive check valve only to find out the cooks had a y hose on a mop sink, and they left the hot/cold on all the time, and just used the shutoff on the end of the hose. hot water flowed into the cold lines, causing only hot available at faucets.
