Does Your Water Heater Have An Expansion Tank? #helpingothers #diy #plumbing

What happens here

This video demonstrates how to install an expansion tank on a water heater. First, measure the house water pressure using a pressure gauge. Next, check the air pressure in the expansion tank and adjust it to match the house water pressure. Then, apply sealant to the threads and connect the tank to the cold water line of the water heater. Finally, secure the expansion tank with a metal strap.
