Just did my first winterization on a Tab 400. We're planning on an early winter trip, so I blew out with air to make un-winterizing easier (less flushing?). Couple of questions:
Everyone's instructions say to open the low point drains one at a time, then do the same with the Alde pressure relief valves. Why can't I open everything at the same time?
When I did open the low points (one at a time, even if I don't know why), I didn't get any water out the hot water one, and not too much out the cold water side.
Also, I don't think I got 2.5 gallons out the Alde drain. Since I ran the pump and opened the taps first, would that take most of the water out?
Finally, and most importantly... if it's winterizing when we decommission the trailer for the season, why isn't it called springizing when we put the trailer back into commission?
