I don’t have an issue with the (dumb) water heater currently in the house, but have a recirculation pump issue – perhaps someone can shed some light. When the pump is running, hot water is migrating all the way back through the system causing the ice in the fridge to melt and hot water to come out of the fridge water port. I checked the recirculation valve (under the sink in the furthest bathroom), but it seems to be working correctly: if I turn off the cold water input valve for that sink, then try to run cold water at that faucet, it slows to a drip. But with the cold water valve on, if I try to run cold water at that faucet it is hot.
What else in the system could be causing this?
