I have a customer with a dead pump that my plumber will replace. Single circuit residential. The old pump was a a Bell NRF-22. I have 2 questions:
1. Was the Bell & Gossett NRF-22 an acceptable pump? I thought that is a hydronic pump and pretty high flow. Was it proper to use it as a hot water tank circulator?
2. My plumber likes the Laing UCT-303 as it has everything built in: check valve, adjustable thermostat, timer, air vent and even a ball valve shutoff. Is this a good pump? Are there any better pumps out there with all those features (or more) built in?
