HELP: Suburban SW12DEL propane issue

Is the WH in a slide room? Also, oily build up in LP systems can cause a problem on just 1 appliance, if that is where the oily build up happens. Also turn on the Range LP burners on HI. Then start the Gas furnace and see what the range burners do. They should not pulsate or diminish. If they do, your LP regulator is bad. Doug

Doug, thanks for the reply. Sorry for the delayed response. Had some work to focus on.

The water heater is not in a slide out. I turned on all burners on hi and kicked on the furnace. Steady Eddy as the heater fired up as well as when it shut off. So the regulator appears ok.

Here’s where it gets interesting. My pressure relief valve was dripping. Originally, I said all the time but mainly cuz the water was hot and I’m in AZ so it takes a while to cool down. It was dripping at full heat about once per 2 secs at its worst. And it was splashing around the orifice as well as on the 12v leads going to the solenoid. No doubt a short would have effected the operation. I wrapped some tin foil around the pressure relief spigot to help redirect water away from the solenoid but apparently didn’t let it dry out enough. Today I ran the water heater with the foil redirecting the drip and everything operated properly. We topically leave the WH on all the time but at the moment for obvious reasons I have it off. I’ll run through a few more tests in the coming days as we turn the WH on as needed.

My new pressure relief valve should deliver today so I’ll replace it this weekend. Do these things just start to drip all of a sudden? I’m guessing it either has some hard water issue or it’s just weakened over time.
