During our visit, a new Grundfos recirculation pump was installed. A couple ball valves and a new spring check valve were installed as well. The system was tested for leaks after completion. The new pump performed accordingly. NOTE: A discussion was had with the customer regarding the water heaters not being up to code. There is no expansion tank either. Options were provided to correct these issues. The customer opted for the check valve and Recirc pump replacement only.
