If the FW pump doesn't have a winterization valve then add one. It will install on the suction side of the pump with a valve to choose between using the winterizing hose or the FW tank. Also do not put antifreeze in the water heater.

I agree that I shouldn't, but again that's what the owners manual says. I will try to put a siphon hose on it but the pump is in a VERY tight location between two walls. No slack in any of the hoses. That may be why there isn't one. Reading through some of the other owners it seems like they are pouring it in the FW tank also. Bad design regardless when you have to use Gallons of antifreeze to winterize a small amount of hoses.
