Why Do Conventional Water Heaters Have Pressure Release Valves?

Every year, your water heater serves an essential function in your home. Your morning regular simply would not be the same– or nearly as comfy– without hot water. Water heating systems and their parts do not last permanently. Preventative maintenance is the crucial to guaranteeing that your water heater continues to safely supply your house with hot water. In this article, we’ll review an important safety component of your water heater, the water heater pressure-relief valve.

We’ll discuss what it is, what it does, and how to guarantee it’s still working and protecting both your hot water heater and your home.

What is the water heater pressure-relief valve?
Well the name explains it all. It’s a valve that alleviates excess pressure in the water heater tank. By doing so, it can avoid excess pressure buildup that has the possible to cause a tank burst and flood your house. It’s an unheralded however vital security mechanism for your hot water heater.

Checking the valve
We recommend that homeowners here in Chicago check their pressure-relief valve when they flush their hot water heater twice every year. Bundling your water heater maintenance jobs together makes sense, considering that each of these jobs takes about 10 minutes to complete.
