I have a 95 Jayco. The last 2 times camping when I filled the water heater and turned the pilot on water would gush out of the relief valve after heating the water. I then have to turn the water heater off. I was using water from my fresh water tank. Not that that makes any difference. I have added a photo of where the water is leaking from.
Thank you in advance!!
In the meantime, try flipping the over-pressure valve lever open and shut a few times, when there's pressure in the water system. Doing that might help reseal the pressure valve. But do replace it.

I carry a spare in my parts box. Never know when it will fail. I also carry extra toilet repair parts and A/C capacitors, along with miscellaneous plumbing washers.
