[A/S] Winterizing - Pumping proceedure

["Bill Czygan" <billczygan@xxxxxxx>]

I have a demand system on my 1970 Safari.
When I pump air through the water piping system (to winterize) from 
the hose connection at the rear, which faucets should be opened 
first? Do I work from the farthest away and highest up toward the 
back and down? If so why? Should I work with one tap at a time? 
Should any particular point be left open to keep pressure from 
damaging the system or is it OK to close all except the one I'm 
clearing as long as the pressure isn't above 50 psi?
When I use the pump (It's at the front of the system under the galley 
sink) to fill the water supply system with redpop (antifreeze) which 
end do I start at? Do I work from top down and front to back? Why? Do 
I close the 4 drain valves while doing this? I have bypassed the 
water heater and will draw from the gal jugs leaving the water tank 
empty. Also know to dump some in the traps, toilet etc.

Still trying to get this straight in my head.
