Hello forum, I own a 1964-built 3,000 sq ft ranch home in Connecticut. I DIY-installed a Watts 50080 today to try to alleviate how long it takes hot water to get to the master bathroom through 3/4" copper through this long house. I got the kit installed, which per the instructions included placing the pump on the hot outlet of the tank and installing a Grundfos valve under the farthest sink. Then it dawned on me - this house has an existing dedicated 3/4" copper return loop to the tank. I am guessing the Grundfos valve is not necessary for me and the way I configured this kit, which was evidently intended for retrofitting to homes that do not have return loops, is not optimal for me.
Since I already own this 50080 kit and can't return it now, can I move the pump to the cold return port at the hot water tank so it is pulling water from the end of the loop, rather than pushing hot water out of the tank, and delete the Grundfos valve? Will I need to add a check valve between the cold (well) water and the domestic hot water tank, or can the Watts recirculator pump just be relocated to the cold return?
I have oil fired domestic hot water.
Thanks
Steve
