During prper winterization, the water in the bottom drain is usually "blown" out with compressed air. How this happens, is that a pipe with a schrader valve (the same type of valve on a ture intertube) is inserted into a pipe that is threaded into the pipe below the skimmer (with the leaf basket removed) An air compressor is then used to fill the tube with air. The air forces the water out of the entire pipe. Bubbles will come up from the drain when all of the water has been blown out of the pipe. The pressure of the air being in the pipe keeps the water from flowing back into the pipe. Hope this answers your question.
Why would you drain your pool just becasue the water is hot? Never drain your inground pool unless you have first cut holes in the bottom of the pool to keep it from floating. If the water table in your area is high enough, your inground pool could "float" out of the ground, effectively ruining your pool.

If they feel main drains are not required that brings their marketing/ sales practices into question.
Vacuum the pool. If you have to drain it, only drain it half way. Floating pools are a disaster.
The water sinks to the bottom. If your pick-up in near the bottom your engine will quit. You will need to drain the tank.
Most electric pumps have a guard at the bottom to prevent leaves and such from getting into the pump. Unfortunately, you need to have usually about 1/2" to 1" of water in the pool for the pump to work. I would suggest trying to drain the remaining water with a hose.
Adjust the float in the bottom of the carb.It is a trial and error adjustment, bend the tab for the pin little by little.do not mess with float height if was running ok before storing up sticky float or muck in carb are causesCheck to see if the screw on bottom of carb to drain the carb was left open from last fall's winterizing!
