Winterizing

Stephen -

Just my own list.

Raise the front end about 4 inches higher than level to assist draining of water lines.
Open drains under the trailer at the rear bumber
Open the drain to the fresh water tank
Open all faucets including exterior shower
Remove drain/annode plug from hot water heater and then pick up drain/annode off the ground :-) because it typically blows right out!
Close valves on the water heater (under the oven) to keep anti-freeze out of the water heater
Drain the black tank into a bucket (if you forgot to dump the last trip out) to make sure no water remains in the tank or line
Use an air hose and adapter to blow the water out of the black water flush line at the rear of the trailer
Drain both grey tanks into a bucket (if you forgot to dump the last trip out) to make sure no water remains in the tank or line
Close all of the holding tank drain valves, but leave off the covers for now
Set the valves at the pump for suction from an anti-freeze bottle
Close all faucets and start the pump
Open faucets bathroom sink & shower), kitchen sink and outside shower one at a time until you get a good pink color
Flush the toliet a few time and leave a cup or so of anti-freeze in it to protect the seals
Pour two or three cups of anti-freeze down each drain to make sure no water remains in the s-traps (dont't forget the shower valves and drain)
Turn off the pump and reset the suction valves at the pump to normal operation
Button up everything and wait impatiently for Spring - remember to flush out all the anti-freeze before the first trip out (makes the coffee taste bad!

Good luck!

I remove my battery and keep it in my garage where it won't freeze, also don't store the battery directly on concrete. Leave the fridge and all cupboards open so air can circulate. I use 2 Drizair filters in my 25' Coyote and place them in the front and back on plastic trays from the dollar store.
