Low point drain 178 - Event Date: 10 Nov 2013 - 30 Nov 2013

when I blew out my lines, I hooked up my compressor, set it to 30 psi or so, opened the low points and let it blow for a few minutes, then did each valve separately, and let it blow until I felt it was as dry as it was going to get.

In all honesty, my take on it is this.. your pod is plumbed with PEX. PEX can be frozen solid and it will not burst. Seen, it done it. In fact was just thinking the other day of doing a demonstration directly of such, since I have some PEX tubing and fittings laying around.. The big danger, IMHO is the water pump, faucets/valves, P traps, and WH. NONE of those will survive a freeze. They are what you are trying to protect with winterization. So, no matter what method you use, as long as THOSE are protected, the rest is gravy.

In the instructions I've posted (link in my sig), I recommend opening the low point drains, and the other valves, one at a time.  Just long enough to see dark pink.
