Can You Replace a Water Heater Drain Valve?

This can cause problems with the performance of your water heater and may even lead to leaks. Draining the tank on a regular basis (every few months) can help prevent these issues. If you do need to replace your water heater drain valve, it’s a relatively easy process.
You’ll need to shut off the power to your water heater and then disconnect the cold and hot water lines from the unit. Once those are disconnected, you can unscrew the old valve and screw in the new one. Be sure to use Teflon tape or pipe sealant on all of your connections to ensure a tight seal.
