Sprinkler pipe will work until it doesn’t. It’s easy to crush and blows apart with much less ice pressure than rigid PVC. For all the time I spend fixing lines each spring (after they were blown out with a tow behind commercial compressor). I would never ever use them for my pool under the patio and deep/not easy to get to everywhere else.
