To drain a pool with a garden hose, put one end of the hose at the bottom of the pool, and create a siphon on the other end with suction. Once the siphon has begun, water continues draining out until the end of the hose in the pool encounters air.
- Drop one end of the garden hose into the pool
Place one end of the garden hose at the bottom of the pool. Attach weights to it with wire, or get into the pool and guide the end of the hose to the bottom, setting a rock on top of it to keep it from floating up.
- Create a siphon on the other end of the hose
Put your mouth around the other end of the house, and start sucking the air out. Keep sucking until you feel pool water come through the hose and hit your mouth.
- Let the pool drain through the hose
Set the end of the hose that you just siphoned down on the ground, and let the water keep flowing out onto the ground. Watch to see that the end of the hose in the pool stays on the bottom, and wait until virtually all of the water in the pool comes out this way, as the siphoning does not end until an air pocket hits the other end of the hose.
