CUSTOMER REVIEWS

Rated 4.4 out of 5 by 32 reviewers.
Rated 5 out of 5 by Solves relief valve leaks from hot water expansion. After installing our new hot water heater (from Home Depot). I saw that when the tank heated the water, expansion of the water occurred, causing the relief valve to leak water. I installed a water expansion tank and the problem was solved. This also added a surprised second fix. . .. . the water pipes would knock when the toilets would shut off, this reduced that noise, sometimes eliminating it completely. . . cool. Follow the directions, air the tank prior to installation, to what your water pressure is. . . See the photo of our installation. . .as you scroll over the photo you will notice we were restricted on room - but it worked nicely. February 13, 2013
Rated 4 out of 5 by Installed without problems. Followed instructions, installed without problems. Note, if tank is installed sideways. Weight must be supported. June 10, 2014
Rated 5 out of 5 by Fixed Hot Water Heater Relief Valve Leak My hot water heater's relief valve was leaking, and I replaced it. Unfortunately, the new one exhibited the same problems. A pressure gauge on the hot water heater determined that my home's water system was closed, and the relief valve was just doing its job. I installed this expansion tank on the cold water line going into the hot water heater. It lowered the pressure and resolved my dripping relief valve problem. Please be aware that you will have to pressurize this tank yourself, before you install it, based upon your water system's pressure. I had do 5-6 wraps of Teflon Tape to prevent it from leaking.

Rated 5 out of 5 by required on a "closed system" After installing a new electric HWT and a pressure reducing valve I required a thermal expansion tank so the heated water volume could go somewhere. I inflated the tank from 20 psi to 76 psi (the same psi as I set the pressure reducing valve) before installing on the cold water line over the HWT using a copper T with a 6" extension of 3/4" copper pipe sweated to a 3/4" female threaded copper adapter. Wrapped the male 3/4" nozzle on the tank with Teflon tape and screwed the tank onto the female adapter and the maximum pressure on the hose bib is 80 psi. No more leaking of the relief valve or my Delta kitchen faucet from the past 160 psi with the HWT on. I have braced the cold water line at the copper T to support the weight of the TE tank which can be mounted vertically up or down and horizontal with adequate support. April 14, 2014
Rated 5 out of 5 by Installation was a breeze. My old expansion tank sprung a leak. After I turned off the circuit breaker and main water and did some quick online homework, I purchased this tank as a replacement. I also purchased a water pressure tester, which you have to use to install the tank. Installation was very easy, requiring a bicycle air pump, tire pressure gauge to check your inflation, teflon tape, and a large wrench. This is handy info for someone who has to do an emergency repair like I did. September 26, 2012
