Good post but I'd like to add one thing. When you put the hose (take off the nozzle) in the pool put it at the deepest part of the pool and weigh it down with something (I use a brick). If that end of the hose floats up and hits the air the siphon won't work!If you want to be able to change the water without lifting a heavy pool full of water, you can make a siphon with your water hose. Just put the hose in the pool, turn it on for a few seconds, then turn it off and unscrew the end from your spicket. The water should drain. You can use the dirty water to water your plants or grass. I have a sump pump that I use to drain the water because it is faster. Then I can easily lift the pool to rinse out since it is empty. I just have a plastic kiddy pool from Walmart. I didn't buy my pump because my husband got it from his grandpa's house after he passed away. I Googled it and it doesn't look like they sell this exact one anymore, but it is a Water Dragon Submersible Utility Pump.
