Common Causes
High water pressure can cause the relief valve to drip. Water pressure inside the heater should be controlled. Excessive pressure can damage the valve and other components. Use a pressure regulator to manage this. The valve may open to release excess pressure, causing drips.
Water heats up and expands. This is known as thermal expansion. The increased volume puts stress on the system. The pressure relief valve opens to release this pressure. This can cause a drip. An expansion tank can help manage this issue.
Identifying The Problem
Check the pressure relief valve for any signs of dripping. Look for water stains or moisture around the valve. Ensure the valve is properly closed and not corroded. If the valve seems old or damaged, it might need a replacement.
Use a pressure gauge to test the water pressure. Attach the gauge to the drain valve. Turn on the water supply and read the pressure. Normal pressure should be between 40-60 psi. High pressure can cause the valve to drip. If pressure is too high, a pressure regulator might be needed.
Tools Needed
To address an RV water heater pressure relief valve dripping, you’ll need a wrench, Teflon tape, and a replacement valve. These tools ensure a proper and efficient fix.
Wrench Set
A wrench set is essential. Use it to loosen the valve. Make sure the set includes different sizes. This helps in fitting various nuts and bolts. Using the right size prevents damage. Always have a complete set handy. It saves time and effort.
Pressure Gauge
A pressure gauge checks the water pressure. Connect it to the heater. Read the gauge to see if pressure is too high. High pressure can cause dripping. Adjust the pressure accordingly. Keep the gauge in good condition. It ensures accurate readings.

Safety Precautions
First, turn off the water supply. This stops more water from entering the heater. Next, locate the main water valve. Turn it clockwise to shut it off. Make sure the water stops flowing. This step is crucial for safety.
After turning off the water, release the pressure. Find the pressure relief valve on the heater. Slowly lift the valve to let out steam. Be careful, the steam can be very hot. This step prevents accidents.
Replacing The Valve
First, turn off the water supply. Then, relieve the pressure by opening a hot water faucet. Use a wrench to unscrew the old valve. Be careful not to damage any nearby parts. Ensure all water is drained out before proceeding. Inspect the valve seat for any damage.
Wrap the threads of the new valve with Teflon tape. This helps to prevent leaks. Next, screw the new valve into place by hand. Tighten it with a wrench, but do not over-tighten. Turn the water supply back on and check for leaks. Ensure the new valve is working properly.
Testing The New Valve
First, turn off the water supply. Make sure to release any pressure in the system. Next, carefully inspect the area around the valve. Look for any visible signs of leakage. Tighten the valve slightly if you see drips. Replace the valve if leaks continue. Always ensure everything is dry before finishing.
Check the pressure gauge on the water heater. Make sure it stays within the recommended range. If the pressure is too high, the valve may drip. Lower the water pressure if needed. Regular monitoring can prevent future issues. Always ensure the gauge is working correctly.
Preventive Maintenance
Regular inspections help keep the RV water heater in good condition. Check the pressure relief valve for any drips. Look for leaks around the valve area. A small drip can become a big problem fast. Inspect the valve at least once a month. This simple step can save you from costly repairs.
Proper pressure management is key to a healthy water heater. Use a pressure regulator to control water pressure. Too much pressure can cause the relief valve to drip. Keep the pressure below 60 psi. This helps the system run smoothly. Always check the pressure gauge. Make adjustments as needed to maintain safe levels.
When To Seek Professional Help
Persistent dripping from an RV water heater pressure relief valve indicates a need for professional help. Ignoring this issue can lead to serious damage and costly repairs.
Persistent Issues
If the valve keeps dripping, it might be time to call a professional. Regular DIY fixes may not work. Constant leaks can signal a larger problem. A plumber can check the entire system. They have the tools and skills to find the issue. It’s better to be safe than sorry.
Complex Repairs
Some repairs are too hard for a beginner. Complex issues need expert hands. If you try, you might cause more damage. Professionals know the right way to fix things. They can save you time and stress. Always hire a professional for tough repairs.
