Plumbing device and method

A method of plumbing a hot-water recirculating pump into a hot water line, the pump having a connecting flange with a pair of spaced apart holes for receiving connecting bolts comprising:

• providing a section of copper tubing having a flare at one end, the flair comprising an annular disk positioned at a substantially right angle to a longitudinal axis of the section of copper tubing;
• providing an installation flange having an inside face for mating with the connecting flange, the installation flange having a central hole for receiving the section of copper tubing and further having a peripheral shape corresponding with the shape of the connecting flange and further having a pair of spaced apart holes corresponding with the pair of holes located in the connecting flange;
• inserting the section of copper tubing through the central hole of the installation flange, and positioning the flared end against the inside face of the installation flange;
• positioning a gasket between the installation flange and the connecting flange, the gasket having a central hole positioned to provide fluid communication from the copper tubing to the recirculating pump, the gasket further being shaped to have a peripheral shape corresponding with the shape of the connecting flange and further including a pair of spaced apart holes corresponding with the pair of holes located in the connecting flange;
• inserting a pair of bolts in the holes provided in the corresponding holes of the connecting flange, gasket and installation flange;
• threading onto each of the ends of the bolts a nut for clamping the connecting flange and installation flange together sandwiching the gasket in between;
• connecting the section of copper tubing in fluid communication with the hot water line.
