Suburban hot water heater questions
Suburban brand. 2 questions if anybody knows. 1. On the pressure relief valve...is the thread... hose bib size? 2. On most RV's is there a check valve on the water (incoming or outgoing)?

I've never actually compared them, but I feel pretty certain the pressure relief valve is threaded the same. Check the valves though, I do think they come in different temperature settings, at least, they use to.
If you have a single valve water heater by-pass on your water heater, then yes, you do have a check valve on the hot out side.
If you have a 2 valve water heater by-pass, you might have a check valve on the hot out side.
If you have a 3 valve water heater by-pass, you probably do not have any check valves.
Thanks...I don't know how many by-pass valves I'll have to check.
