Questions & Answers
how do you know what air pressure you should use. Instructions show a air gauge is needed but no...
Asked by Stephen February 7, 2019Use a water pressure gauge to check the water pressure in your house. You can usually screw it on the laundry tub faucet like you would a garden hose then turn on cold water and read the pressure you want your expansion tank to have the same pressure as the house pressure. To read the tank pressure use an air pressure gauge you can use the gauge that you use on a car tire. Fill or release tank air pressure to match house water pressure.

Asked by Henry November 11, 2019In the old days they weren't needed because when the heated water in the house expands, it could push the excess back into the water main. But new codes require that water meters incorporate check-valves to keep water in the house from going back into the main and possibly contaminating the public water supply. As a result, especially when you start up a water heater with a full tank of cold water, and no faucets open in the house, the pressure can climb high enough to (hopefully) open the T&P valve on the water heater or blow out sink hook-up hoses or any other weak part in the system. A T&P valve that seems to often be seeping is more likely caused by the lack of an expansion tank. Very often the water district will "upgrade" the meters without telling their customers that they had better install expansion tanks.

Asked by gene January 11, 2019Cold side.
Should this be installed with a Tankless Hot Water Heater? If so, how does one know which size Expansion Tank to utilize?
Asked by Paul November 24, 2019Since almost every residential system has a check valve between street and house your water heater irrespective of type is a closed loop system. If you have a recirculation pump/loop on your heater you should definately have an expansion tank. Many cities now require the tank no matter what. More and more Tankless heaters have recirc pumps built in. Theres a 99% chance (give or take a percent or ten) your system is closed loop if residential.
can this be installed horizonally
Asked by CHUCK January 13, 2020Took me less than 10 minutes to install. Draining the water from the lines took longer than the install.
Is there pressure when replacing the tank
Asked by 1020 January 29, 2019yes there is pressure. you will have to turn off the water main and drain the pressure at a sink.

Asked by Paul March 27, 2020yes mine is installed that way. However I ran a metal support line to a ceiling joist for added support.
