Concrete pools do not "cave in", however part of the pool can rise 2' above the ground. This is caused by hydrostatic pressure which exists beneath most Swimming Pools. As the pool is emptied, the weight of the water is reduced and, eventually, the hydrostatic pressure (underground water) is sufficient to lift a portion of the pool high enough into the air to eliminate the pressure. This can be easily avoided by removing the hydrostatic relief plug(s) as the water level drops. Concrete and gunite pools have some form of a relief valve underneath the drain cover. Pools 20'x40' and larger also usually have 2 additional relief valves. They are located on each side of the "steep slope" and should be removed as soon as the water level drops below them. As a final precaution, only empty the pool when it's not during the rainy season, unless it is an emergency. In most of the U.S., the fall, between Labor Day and the end of October, is the best time for cosmetic projects because of less ground water and less rain delays.

NO however you should keep in mind that the ground water outside of the pool is not going to put pressure on it as this is capable of even lifting a concrete pool out of the ground.

Vacuum the pool. If you have to drain it, only drain it half way. Floating pools are a disaster.

When installing a shower drain in a concrete floor how do you determine the height of the drain which will protrude through the concrete?
First determine what you are going to install as the shower unit. If there is to be no shower unit and it will just drain through the concrete floor, then it will be flush with the floor. If you are installing a unit, then you need to look at the unit to determine the distance obove the concrete to place the drain.
Is it wrong to drain your plaster pool when the temperature is above 100?
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 you have an inground gunite pool that was drained using the pump why can't you develop suction to drain it out now that there is only a bit in the bottom?
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.
