What's happening when the shower head valve is shut off is the cold water is pushing the hot water back in the line so when the valve opens you get a cold blast first. I installed check valves on our shower hot and cold lines at the faucet inlets to prevent the back feeding when the shower head valve is shut off. Problem solved...
AWESOME I'm going to look into this.
I wouldn't do that if you live in areas of freezing weather. But that's just me.
I've used the check valve setup for years in upstate NY. It doesn't affect either winterizing method, pumping RV antifreeze or blowing air through the lines.
