Very new to this! I have an 87 hrc 37 ft RV I desperately need manuals. Or info : how do I close the potable warter valve? What's the 3 way rotary switch for under the closet? Plus a few more but these are the MOST important at the moment PLEASE HELP??
The 3 way sw in the closet is probably the Hot water heater by pass for winterizing. Be sure there is water in the hot water heater before turning the hw heater on. Not sure what you are talking about on potable water. Mine is a 2 way valve one way fills the fresh tank and the other way supplys shore water to RV. Pic would help. Just post all questions you have.
