If I missed this, I am sorry...
1. Some of us do not have the winterizer plumbing- and must pump antifreeze in via the external hose hook up.
2. That means some fresh water might live just upstream and downstream from the pump.
I would THINK that the antifreeze would diffuse up the pipe.
I would THINK that upstream from the pump would probably be open enough that freezing is not a problem.
BUT, for the pump itself...seems worrysome that water might be trapped in the pump and break the pump.
AND...along these same lines- is it enough that you pumped the tank dry and have the pump sucking air (some air, but still gurgling with amounts of water.
Yeah, it's PROBABLY all OK, but who knows for sure.
In my case, I have put a small amount of antifreeze in the fresh tank and tried to run the pump...no clue if it get's picked up.
Yes, in the spring, I do need to fill and drain (via the drain plug) the fresh water tank several times and sometimes do get a little bit of foaming later...no aftertaste, and it's non toxic anyway...but maybe not as big of a hassel as some folks make it out.
Anyway- bottom line- for those of us who don't have the winterizing plumbing where antifreeze pumps THROGUH the pump...how dangerous is the pump and it's left over water...even if you run the fresh water tank 'dry' (which is far from dry).
