Count me as a compressed air fan. No pink stuff in my freshwater system EVER!

I use both methods in conjunction. I blow out the lines with air and then pump 2 gallons of pink through the lines and pour some in the traps.

could be overkill......but the pink is cheap.

I do just like many of the previous posters do. I did away with the water filter canister the first week I had the trailer, and tied the lines together.

I drain the water heater, blow out the lines (making sure to clear out any water in the outdoor/indoor shower heads), and add some pink stuff to the p-traps and top of toilet...............for the four days a year it get's below freezing here.

I do the blow out method but have found that all one needs is a bicycle tire foot pump (hand operated) to blow out the lines. It costs about $10 and can be used anywhere the coach is located without the need for electrical power. The only item needed is the standard plumbing blow out adapter that has the schrader valve. All lines and low point draines can be completely blown out. DW is usually inside unit to open and close all faucets including toilet flush. Anyway, this approach works for me and I have had no issues with any coach I have owned.
