Do I need some kind of heat loop?
Hey folks. We have a single-arm kitchen faucet on which the cold side draws warm water when we turn on the cold. Eventually it runs cold. After it runs cold and we turn off the water for a few seconds, turn it back on, it stays cold for a few seconds then warms up for 10-20+ second And then finally goes cold again.
It’s a Grohe faucet and I’m outside the US so it was easier to get a new faucet than import a cartridge. The new faucet has the same problem!
I think I must be getting hot water from the inlet of the tank. I don’t know how to stop it. No room for a check valve and expansion tank. Any thoughts appreciated.
DIY'er ... ripped out a perfectly good forced-air furnace and replaced it with hot water & radiators.
