I have been using the pink stuff for 20 years. Last year I bought a small air compressor that I can regulate to 50 psi. Now, after draining the tanks and bupassing the water heater, I hook it to my water inlet and go from point to point, allowing the air to blow through until there is little or no water coming through. I still use the pink stuff in the traps and run it through my washing machine pump and don't use it until warmer weather.. I disconnect and drain the ice maker.
It is so much easier than the pink stuff and if i decide to make another trip it's easy to do it again.
As for the wet bay: I run one of
these little things on low (175 watt) setting.
