TL;DR
The main drain is the suction fitting set into the deepest point of a pool floor that draws water to the pump for filtration and allows the vessel to be emptied. Modern installations use two drains plumbed together at least 3 feet apart, or a single unblockable fitting, to eliminate entrapment hazard under the federal VGB Act.
