I use my Viair to get the majority of water out of my system. I do have a 2 gallon accumulator tank installed to cushion the air/water pressure. I also have a ball valve on the hose that I use to attach to my trailer. I get everything set up with the valve closed and pump on. Then I open the ball valve and steadily go thru the trailer opening and closing my faucets and toilet. Once I am almost dry, I leave the last faucet open and turn off the pump to clear all pressure. Then I close the valve at my accumulator tank and pump in antifreeze, I don't want to get antifreeze in the tank. I like the added insurance that having pushed antifreeze into all the spaces in the faucets and water pump. Haven't had an issue with plumbing since following this routine.
