Hello, I am hoping that someone can help with this issue. After my plumber relocated the recirc pump to make it more accessible for a repair, there arena three hot water faucets in the house that can only get cold water. The rest of the hot water faucets are just fine. When the circuit breaker to the recirc pump is turned off, then all of the hot water faucets in the house get hot water. However, as soon as it is turned back on, those three faucets only get cold water. He is perplexed by the issue and does not know what could be causing it. Any thoughts? Thanks in advance.
