Hi, Ron.............sorry for the delay in someone getting to your question. Weekends can be hectic and some of our techs are gone this weekend. I believe the pump is on one of the driverside bays where the water hookups are. It may be hard to see and some of these you have to remove a panel to get to them. If you can see it, you should be able to get to the inlet side of them pump and install a winterizing valve and hose. It would go right behind (tank side) the filter. You can make one up using a FlairIt 3 way valve and piece of 1/2" hose so you can suck the antifreeze right out of the jug. The nice thing about those is that they can be installed further back on the inlet water line IF the pump is not easily accessible. If you need more here, please attach a photo of the pump area to your post and I can comment further. All follow ups are included in our fee.
