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.
