Hot water circulator

Hot water Installation

Remove the shutoffs under your sink after turning off the main water supply. Be sure to open the water valve outside to relieve the pressure in plumbing lines. The shutoffs shown here are attached with compression fittings that you can remove with an adjustable wrench. If your shutoffs are soldered on, remove them with a mini tubing cutter or a hacksaw, cutting as close to the shutoff as possible. Mount the hot and cold shutoffs on the unthreaded end of the copper tees, using the compression ring and compression nut that comes with the tees.

Attach the flexible water heater connectors to the tee bottoms, then to the threaded elbows of the pump unit. Bend the flexible connectors gently into shape to line up the end nuts with the threads on the pump elbow. The Pump unit can either hang suspended on the connectors, since there is no noise or vibration.
