RV Propane Regulator should maintain/hold 11" WC on the system with 100% of ALL propane appliances in use.
Testing S/B done with at least 50% in service.
11" WC----that is roughly 0.4 psi (less the 1/2# of pressure)
Suburban water heater uses a 12,000 btu burner (big flame)
So you changed out the solenoids.....but did you remove orifice and clean it??
Soak in alcohol and then blow it with LOW Pressure air...very low pressure otherwise you can damage orifice
Also.......
gas valve ONLY opens and allows gas to flow for 6-8 seconds during 'trail for ignition' ----no main flame lighting off and proving t lit circuit board drops DC to gas valve (SO no build up of raw fuel)
If propane has not been used for a while or a fitting has been loosened etc then it can take a few tries before the propane reaches all the way to farthest appliance.\
Light off all stove top burners on HIGH...do they all burn the same or do they diminish as another one is lit??
Good flames....leave running and try Water heater again...couple times.
