So glad you responded. OK, here is what I have accomplished so far. And I'm not AT ALL confident lines are blown clean

I was going to make your adaptor and the more I looked at your directions, I couldn't see what the difference between the function of IT and the gizzmos I use every year. The gizzmo has removable plug on the end that a winterizing plug fits into perfectly. So I put a schraeder valve thru the winterizing plug and hooked my 135 psi air compressor up to that thru gizzmo that was screwed into the skimmer.

The deep end return started blowing first. But it wasn't consistent air bubbles. What I mean is that it would blow big bubbles, stop for a few seconds and blow big bubbles again. I let it go for at least 15 minutes and it continued to do that with no change. So I figured that must be how it works. I worked my way around the 4 returns and then the polaris jet.

Next I did the other skimmer. It blew water, but not up into the air like it does when the pool people do it. When they do it, water blows up like a geyser. Mine just "bubbled" and again seemed to bubble out, then suck in, bubble out, suck in... It did NOT instill confidence at all...

Then I tried the main drain. I got lots of bubbles, then nothing. At no point after that first 15-20 seconds of bubbles did it appear that ANYTHING was coming out of the drain. No air, no water. No ripples in the dead calm pool water at all. Shouldn't there ALWAYS be bubbles or movement or SOMETHING?

I couldn't figure out how to get air going thru the fountains. I wonder if that is a totally closed system. We never used them this year, but I think they still need to be blown. They have their own pump, but that pump hasn't worked for at least a year...

Then I drained the filter (DE) by unscrewing the plug and the pressure gauge. I leave those off, right?

Then I drained the heater (2 plugs) and turned the propane off.

Then I drained the two pumps. (2 plugs each)

There is 5" of snow forecasted for tonight. So I'm really hoping I will be OK for the next day or two. But I've got to figure out if there is still water in the lines.

Biggest concern RIGHT NOW is the equipment, since water will no longer be circulating thru them: do the heater and filter and pumps just DRAIN or do they get BLOWN? All I did was drain and leave the plugs out.

Should I ever hear ANY "gurgling" in the lines once the lines are "blown"? My guess would be NO. And I did hear some gurgling. So I"m concerned...

I'm so sorry to be such a pain. Thanks for your time and help.
