HELP. NEWBIE - winterizing questions
This is my first time posting in any forum and I am not to computer savy. I just purchased a 2002 Fleetwood BOUNDER and am attempting to winterize it. I have winterized smaller TT'S, so I know about HW Tanks and Bypass valves and how to add AF. My problem is that I have never had a water bay. My BOUNDER in the water bay driver side, has a black lever and above it there is a sign BYPASS. My question, is this the HWT bypass or is the lever to fill the water tanks from the city water? I have read some posts and am confused since some say the unit should have a 3 valve shutoff. If so where is it located? On the passenger side where the FW Tank and the gravity fill is located in one compartment bay there are lines which have a large lever ball valve. I am thinking this is for filling the FWT by way of the city water connection and nothing to do with the HW Tank? My last question is when I turn on my HW switch which or when is it heated by propane vs electric, and by turning off the switch, will it shut off both sources, or how does it work? Are there any other HW shutoffs?
Thank you for your responses and help. I have learned a lot in reading posts in the short time as a member.
