Step 2 · Drain the Old Tank

Locate the drain valve (also known as a boiler drain or spigot) on the tank tee at the bottom of the pressure tank. Securely attach a garden hose to this valve and run the other end to a floor drain, sump pump, or outside. Open the drain valve fully. The tank will begin to drain. This process can take a significant amount of time for a 44-gallon tank. To help speed it up and prevent a vacuum from forming, ensure a faucet somewhere in the house remains open.
