My question is does pressurized air do anything to get the water out of the water pump and bypass valves? Everything else seems to blow out pretty well…
1. You will need to disconnect the water outlet for the pump and drain it. Have a towel or something ready. Not a lot of water, but it will be some. I believe it tells you to do so in your AS manual.
2. I recommend cleaning out the inlet water filter and dabbing the water up there as well. It could freeze and damage the filter.
Word of warning. The outlet valve can be a problem leaking if you don't get it tight enough. So should check that when you dewinterize in the Spring. I personally used the anti-freeze as well as blow out the line. I didn't like connecting and disconnecting that valve just because it is a bit of a mess, and I didn't like the fact it had a tendency to leak. And it's pretty easy to put in the pink stuff if you have a valve to attach a hose before the water pump to pump it through the system. Then you don't have to worry about the pump. This year I'm just going to blow out the line since I have heated space for storage in my new garage.
But lots of people just blow it out and are good to go.
