Have you ever turned on your cold water and had hot water come out? Sure, oftentimes, this just means you have to wait for the cold water to make it up through the pipes but this waiting means wasting water that you could have used. In an RV with a limited freshwater supply, this just isn't a good situation. Luckily, there is a simple and easy solution. What is happening in this situation is that the hot water from the hot water heater is flowing back down into your water system and into the cold water tubing, which then travels up to your faucet when you turn it on. By installing a backflow preventer into your water system, you can prevent this from happening.

A backflow preventer is installed before the hot water heater and works by allowing the water to pass only through it in the direction of the hot water heater. It does not allow water to pass through it from the other way. This keeps the hot water from entering back into the tubing and getting into the cold water supply. Made of brass, it's drinking water safe, durable, and rust-resistant. 

To preserve your freshwater supply and keep your hot water hot and your cold water cold, installing a backflow preventer is a must. With this small device, you can keep your water better controlled and keep you comfortable. Have any questions? Contact us online or call our friendly Customer Care team today!
