Use 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.

In 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.

Cold side.

Should this be installed with a Tankless Hot Water Heater? If so, how does one know which size Expansion Tank to utilize?

Since 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.

Took me less than 10 minutes to install. Draining the water from the lines took longer than the install.

I used the Apollo 3/4 pex to 3/4 female pipe adapter, model APXFA3434 from Home Depot with this tank. Turns out that adapter HD carries in store has bad ratings. I have a tiny leak that no matter how tight or how much teflon tape I use won't go away. Going to try the highly rated Sharkbite brand 3/4 swivel adapter. Now I have a scratched tank. This post is more of a warning for others than a product review.

No complaints. I replaced a different model that had a pinhole leak for way longer than I knew. Hopefully this one will hold up longer. I needed to pump it up to 70 PSI to match my water pressure. The upside down installation is OK per the manufacturer.
