Winterizing Suggestion Update

I agree with Dick_B to keep the prime in the pump, and have done both ways. I like draining everything first, otherwise unless you have a place to dump, flushing water out with antifreeze will leave a good bit of water in your black and grey tanks. Of course, you need to pour enough antifreeze into the drains to fill the traps, and doing that will usually put enough into the tanks to prevent trouble. With mone drained, I did have a bit more trouble getting the pump to pick it up. Solved problem by using a funnel into the antifreeze pickup tube, holding it above pump and pouring in enough to prime the pump. Either way works, so its is your preference.
