Fingers crossed it works. If it doesn't, I will have to convert back to the Bestway 1 1/2" flexible tubing after making the 25' run with 2" PVC.
I'm probably missing something, as I skimmed the thread (my apologies)... Is it not possible to cut out the return and replace it with a PVC "standard" sized one?
