Pool water cooling

[stuckpipe]

I am having a sprinkler system put in and was wondering. Can I run 150 of 2" PVC in the trench they dig and connect it to my pool pump. Do you all think it would cool the water down a bit?

Simple answer....no. PVC is actually a pretty good insulator, a lousy conductor of heat, and by just burying it in a trench the area around the pipe will eventually stabilize in temperature and lose any cooling effect. You need to constantly remove heat in some way.
