Why a Tankless Water Heater Check Valve is Necessary
I recently installed a tankless water heater in my home, and one of the most important things I did was to install a check valve on the cold water line. A check valve is a one-way valve that prevents water from flowing back into the water heater. This is important for tankless water heaters because they rely on a constant flow of water to heat the water. If water were to flow back into the water heater, it could damage the unit.
There are a few different types of check valves available, but the most common type for tankless water heaters is a ball check valve. Ball check valves are simple and reliable, and they’re relatively inexpensive.
Installing a check valve on your tankless water heater is a relatively simple task that can be completed in just a few minutes. Here are the steps involved:
1. Turn off the water supply to the water heater.
2. Disconnect the cold water line from the water heater.
3. Install the check valve on the cold water line.
4. Reattach the cold water line to the water heater.
5. Turn on the water supply to the water heater.
That’s it! You’ve now installed a check valve on your tankless water heater, and you’re protected from the potential damage that could be caused by water flowing back into the unit.
Here are a few additional benefits of installing a check valve on your tankless water heater:
- It can help to extend the life of your water heater.
