Question regarding using air to blow out the lines. I have always used anti-freeze but I just did the air deal this weekend, but now I'm questioning the pump. I would guess there is water in the pump since we use our FW tank? We rarely have water hook-up. I am considering still using anti-freeze just so I can get some in the pump. (I still plan on putting some in the traps and toilet regardless) Any thoughts?

Drain fresh tank and all water lines, including inside and outside shower sprayers. Empty water filter housing, let filter dry, and replace housing. Blow out lines using screw-in adapter on city water fill. Unscrew pump filter screen, empty out water, and replace. Run pump for a very short time, check filter screen housing for water and empty if necessary. Repeat until no more water drops appear in screen housing. You should have no pump freezing problem after that.

Some water may remain in the foot pedal toilet valve.

Don't forget your black tank flush lines, if so equipped. Blow the lines with air, no need to run antifreeze. Failure to do so will most likely end in a mess come spring when you decide to do a tank flush. It's not really the lines you have to be concerned with, but the anti-siphon valves.
