Where is the Water Heater Pressure Relief Valve?

How Do You Open the Water Heater Pressure Relief Valve?

When you have a leak or your water heater is not working properly, you can open the water heater pressure relief valve, then, call your local plumber! This way, they can thoroughly inspect the issue to know if the problem is serious or not. You may even need to upgrade to a new water heater. Remember, you do need to replace your water heater every 8 to 12 years.

Of course, it is crucial to ALWAYS read the tank’s owner manual as every tank is different.
