A hot water unit equipped with a hot water re-circulating pump will maintain a more consistent level of heated water to be used through their home. There are always dangers and mishaps that can occur when one is modifying a hot water system, so take precautions when installing your re-circulating pump.
To connect the circulation pump, use the tubing that comes supplied with it. This will be either copper or stainless steel tubing. The lines will connect to the hot water line of the fixture and there is hardly any plumbing involved. Disconnect the hot water line from the fixture then reconnect according to the instructions that came with the circulation pump. The lines will connect using nuts and washers so the only tool you will need to accomplish this is a wrench. Apply Teflon tape to the threads before tightening the nuts and ensure a tight fit is established to prevent water.
