I am planning to install a Grundfos reticulating pump and before i bust my
hot water heater I am hoping to get some advice from you fine folks.
I am not sure how to disconnect the hot water pipe on the hot water heater.
The hot water supply is attached to the heater with a coupling however the
supply pipe is copper and soldered to a joint that screws into a coupling. I
am not sure how to remove the coupling without breaking the soldered joint.
Any thoughts would be appreciated.
