Water Heater Troubleshooting: Leaking Relief Valve
It is easy to tell by sight that water heating troubleshooting is needed. When you see water leaking onto the floor, you know that there is something wrong in that area. When it comes to a leaking relief valve, you will need to do a little further investigating. Here are the steps to take for water heater troubleshooting of a leaking relief valve.
Step 1: Check Outside Valve
The easiest way to troubleshoot your water heater is by checking the outside area of the valve. If you notice that there is a little water dripping out of the valve, then check to make sure that it is seated properly, is all the way closed, and that there isn't anything obstructing the valve so that it can not close.
Step 2: Remove Valve
Using an alligator pipe, remove the relief valve. Check to make sure there isn't any rust or water deposits that have created a small leak around the threads. Clean the area around the threads with a rag and wrap the relief valve with Teflon tape. Replace the valve and tighten it so it is snug. Make sure not to over-tighten the valve.
Step 3: Check Bottom of Valve
If your water heater is several years old, you may see that the valve does not fit as snug as it should. Use some caulking around the valve and pack it in tight. This will help you to stop any leaks temporarily until you can replace the valve or the water heater.
