How to Handle Water Heater Drain Valve Leaks

If you have a leaking water heater, it could be due to issues with the drain valve, pressure relief valve, or water line. However, in most cases, the problem is related to the drain valve. To identify the issue, look for water puddles underneath the heater and check for leaks around the drain valve, which is typically located at the bottom of the heater.

Fortunately, there are several troubleshooting options available. One solution is to tighten the valve by turning off the power or gas valve to pilot, then tightening the valve handle and valve stem nut. Another option is to cap the outlet with a replacement cap, which is ideal for smaller leaks.

If the problem persists, it may be necessary to replace the drain valve. Be sure to consult the water heater’s instructions to properly shut off and disconnect the heater before draining the tank and replacing the valve.

It’s essential to keep in mind that water heaters contain scalding liquid, and attempting to fix the issue without experience can be dangerous. If you’re unsure, it’s best to contact a professional like MET Plumbing & Air Conditioning at 281-603-9949 for assistance.
