For those interested in the172t i found it behind a panel under that stove cabinet nearest the floor. Had to remove 2 square head screws. I replaced the screws with a velcro system for easier access in the future.

Somewhere near the pump there should be a hose with an open 'dead-end' It is connected to the main pump hose with a T-fitting valve. If you turn the valve in one direction, the pump will pull water from the water tank, turn it in the other direction and the pump will suck air through the 'antifreeze' hose because you don't have the open end of the hose stuck into an RV antifreeze bottle.

The valve near the water pump should only be turned to the "antifreeze" setting while doing the winterization, after that you should turn it back.  It won't hurt if you leave it on the "antifreeze" setting, but if you don't turn it back then in the spring you'll wonder why you are getting almost no pressure in the water system.  Like I did last spring.  Embarrassed

I am so glad you are asking (and getting answered) these questions.  I think we are a month away from de winterize.  Dr Drew, are you in Northern or Southern Missouri?

aside from the hot water heater valves...is there another valve that needs to be turned prior to flushing?  i was watching a video today and it looked like they turned a valve to get the pump to accept the antifreeze?  where might that valve be on the 172T?  just dont want to break anything!

I agree that the Propylene Glycol does have some antiseptic properties.  I usually add the 'chlorine treatment into the freshwater tank in the Spring to kill any bacteria that might have grown since the Fall.  I don't add RV antifreeze to my freshwater tank...It would take a couple of gallons of antifreeze to reach the water pump tank outlet.  On my Pod, the freshwater tank drain is at the lowest part of the tank so there is only a film of water remaining. RV antifreeze is fairly expensive and I only use it via the 'antifreeze-winterizing' hose installed at the factory adjacent to the water pump.  Thus the pump and water pipes down line are protected without leaving antifreeze in the water tank and subsequent taste residue in the tank.
