Step-by-step Guide
Dealing with a leaky RV water heater relief valve can be frustrating. But, with the right steps, you can fix it yourself. This step-by-step guide will help you inspect and clean the relief valve. Follow the instructions below to get your RV water heater working properly again.
Relief Valve Inspection
First, turn off the power to the water heater. This ensures your safety. Let the water cool down. Then, locate the relief valve. It is usually on the top or side of the heater. Check for visible signs of damage.

If you see any cracks or damage, the valve needs replacement. Take note of the valve type for a proper replacement. If the valve looks fine, proceed to the cleaning step.
Cleaning The Valve
Begin by turning off the water supply. This prevents more water from entering the heater. Open a hot water faucet to relieve any remaining pressure. Use a wrench to remove the relief valve.
Clean the valve using a mixture of vinegar and water. Soak the valve in the solution for 30 minutes. This helps dissolve any mineral deposits. Use a brush to scrub off any remaining debris.
Rinse the valve thoroughly with clean water. Inspect it one more time for any damage. If it looks good, reinstall the valve. Turn the water supply back on and check for leaks. If the valve still leaks, replacement is necessary.
By following these steps, you can fix a leaking RV water heater relief valve. Regular maintenance can prevent future issues. Keep an eye on your water heater to ensure it stays in good condition.
Replacing The Relief Valve
If your RV water heater is leaking from the relief valve, it may be time to replace the valve. This task may seem daunting, but with a bit of guidance, you can do it yourself. Below is a step-by-step guide on how to replace the relief valve in your RV water heater.
