I'm just wondering that if I flip the control valves to Winterize, does the water filter come out of the loop? Or do I need to pull the back wall down to get to the filter and flip some valves by the filter itself?
Hope that question makes sense.
Well, here's what I learned tonight doing our first winterization - hope it helps another 31FK owner. [ I'm in a 2016 31FK with a Girard Gen II water heater. ]
1. You have to remove the filter from the canister. I didn't see a way to isolate the filter from the flow
2. Closing the valves to the water filter canister stops the flow - leave them open (hence #1, remove the filter)
It took 2 gallons and here's my procedure:
1. Turned off water heater (red off button) outside
2. Flipped valves to "Winterize" (It's '2' and '4' if I remember)
3. Removed water filter from canister, put canister back on
4. Flipped screen on City inlet around, so the peak points in and depresses the check valve
5. Hose from City in, and into pink RV antifreeze
6. Enter coach and flip water pump on.
7. Run sinks (hot and cold), shower (hot and cold) and toilet until pink stuff appears
8. Water pump off. Pour antifreeze down p-traps.
9. Head outside, pump back on and run outside shower (hot and cold) until pink antifreeze appears
10. Pump off
11. Propane off. Power off.
I'm pretty sure that I have a filter canister filled with antifreeze, so be careful when you remove it to put the filter back in.
Hope that helps someone else!
