I seem to have a problem with the hot and cold water mixing . I can't seem to find a spot on the controll that will give me just hot H2O is this an anti scalled thing or is something plumbed wrong? Shower OK just seems to be kitchen sink. Thanks. Scotty.

Check your "winterizing" bypass valves. Make sure they are set correctly. It took me a week to get the pattern right. Then I marked them all for future reference.

I never thought of that! And just in time to winterize again. I will study my plumbing as I do it this year. Thanx for the tip. Scotty.

i had this problem one day and it was the outside shower. i left both the hot and cold faucets on which i figuered was ok because the shower head had a seperate knob to shut the water off. but when you turned a faucet on for hot water the cold water would be pulled through the shower faucet.
