Ah ....the light is in the pump room near the pumps (filter and booster for the cleaner) ...was just postulating this might be yet another safety precaution for the pumps ...might be some conducting through pipes and concrete in the room ...no effect to the MD or pipes outside the room though.
Blowing out a dual line skimmer setup and how dual lines are usually set up...

Most equipment is sitting outdoor where temperatures reach 20 degrees, with strong winds. This is why it is so important to remove as much water as possible.
Right ...everyone's circumstances are different ...all my equipment is in an enclosed, but uninsulated, room ...I don't really want to insulate it since there is a pool heater in there, as well, and it gets warm in the summer, already.
Thanks for advice ...every year I try and do a good job getting the water out of the system - and, at least pushing down the main drain water and air locking it ... but every year I have my fingers crossed that it is good enough

Because MD are so deep and usually equipment is at a higher elevation, naturally the water will go down a few feet. Because the soil insulates everything, I doubt people will run into problems. You should have no issues. If the main drain leaks, that is a serious problem. Honestly, I could do without a main drain. I have mine pulling very little water in my system. What helps me is the rotating 360* heads that constantly keep water going, although PH drifts upwards pretty quickly.

it is interesting that you dont notice bubbles coming from your main drian either. I live in Vancouver Canada. Most we get here on the coast is -10 degrees. So its not like -30 in Alberta or Sk
if I make sure air doesn't leak, I wonder if I should just dump some pool antifreeze down the main drain and then pump 30 pounds of air in it and then call it good. I can always check the pressure later.
I do not know if the Anti-Freeze will do the trick. Main drains should be closed properly, especially in cold environments where cold temperatures last a while. Maybe asking around to see if someone has enough of a blower to push air through the system.
Another idea I have is to just shove a 10 speed bike tire tube into the pipe and then air it up a bit. With the intention of just simply displacing the water further down.
Cuz i just dont trust that the gizmo i have is going to hold air all winter long

If you do not trust the Gizmo, then use a black rubber plug after you push air through the system. The black rubber plugs will give you a tight seal.
Then place either Styrofoam or a bottle with RV Antifreeze (50% full) to absorb any ice expansion so the skimmers do not crack.
