I'm getting hot water in both my hot and cold water lines and faucets when the heater is active. I can't find any kind of reverse flow prevention valve, but my heater IS fitted with a temperature regulator that is supposed to mix cold water with hot and then send it to the red lines. My guesses are:
1. The temperature regulator is somehow allowing hot water into the blue lines
or
2. My deteriorating fresh water pump is somehow allowing reverse flow? My water pump sounds a bit sickly when running.
Thoughts?
