Winterizing '04 25' Safari Water System
We just completed a 7600-mile/54-day trip from FL to MI via AL-MS-AR-MO-OK-TX-NM-AZ-CO-NM-CO, etc, etc, etc in our 2010 Ford Expedition/2004 25’ Safari combo. This was our first “big” trip and it went flawlessly beyond belief. What a rig!
We plan to take it out for the month of Sept and head west and upon returning to MI store it for a couple of months before heading down to FL. Winters may/may not come early up here in northern Michigan and I am thinking of winterizing the water system for those two months or so.
Although blowing the plumbing with air pressure is no problem, we do it every year to our cabin, filling the lines with RV antifreeze would be a good thing to do.
How can I get to the pump to adapt its inlet to an antifreeze container? The best I can tell it is under the sink floor (?), but where is the access?
Although it may be normal, the pump sort of low-level growls as it cycles, even with a full fresh water tank. This is the original pump, but I cannot tell what make it is until I get to it. Is this growl expected, or may I be looking at some bearing or impeller problem? It works fine, just noisy.
BTW, I ran the pump to supplement water pressure at some campgrounds that had low water pressure. However, the growling was there from the beginning.
Any input will be most appreciated. Thank you in advance.
