I once had a pool repairman tell me that running my pool slide would significantly cool the water. I have a wild ride waterslide, the water used to supply it comes directly from the pool from a switch that I have that allows the water to either come out of the inlet or it can be directed to come out of the slide. So, its not hose water or anything like that.
I've never understood why this would cool the water, the drop from the slide to the pool is maybe a few inches or so, so the splash isn't that big. I love to run it but I am always afraid that it will cool off my water.
Does anyone know the answer to this?
