Where Is the RV Water Heater’s Bypass Valve?

Your RV’s exterior will include the access panel for the water heater.

The compartment where your RV water heater usually resides is square or rectangular and has a pull-down panel for simple access.

You will be able to reach the front of your RV water heater from the outside.

The bypass valve for your RV water heater is not here.

The bypass valve for your RV water heater sits within your RV, at the rear of the water heater.

Your water heater anode rod and drain are located on the front of your RV water heater.

When draining out your RV hot water heater for the winter, you’ll spend the most of your time here.

Head inside your RV to the side opposite the one where the water heater is located in the front to find the rear of your hot water heater.

It’s probable that your kitchen stove will cover the rear of your RV water heater, making it difficult to see (or other appliance).

You’ll probably need to use a screwdriver or drill to unscrew and remove paneling and/or other parts that are covering your hot water heater in order to reach the bypass valve for your RV’s water heater.

You will be able to view the rear of your RV water heater and find the bypass valve after the paneling has been removed.

It’s crucial to remember that on certain RV models, merely removing the paneling won’t give you access to the rear of the water heater bypass valve.

To reach the rear of your RV water heater, you may need to remove a nearby panel or cabinet.

Why Do I Need A Bypass Valve For My Water Heater In My RV?

When winterizing your RV water lines, the primary goal of the water heater bypass valve is to stop anti-freeze from getting into the heater tank.

There is no need to add anti-freeze to your RV hot water heater during the winterization process, both practically and economically speaking.

Your water heating system is not at danger of being harmed by the tank freezing or expanding.

Bypassing your hot water heater means sending the cold water that would normally flow into it via the hot water plumbing line.

A valve for the water heater bypass is often fitted in RVs.

You might have one, two, or three bypass valves, depending on the kind of water heater you have.

The fastest and most economical approach to winterize your system is to bypass the water heater in your RV.

Instead of adding gallons of antifreeze to your whole RV water heater tank (which is useless anyhow), just bypass your hot water system so the antifreeze just flows to the water lines that need it.

To properly maintain your hot water system for the winter, descale, clean, and drain it instead of adding antifreeze.

To get rid of any limescale and other buildup that can impair the efficiency of your heater, we advise that you clean and empty your RV hot water tank at least once a year.
