Of the many things I found while planning my pump install was the Jandy sweep elbow designed to provide less hydraulic friction in an elbow. I liked the idea first but when I realized they recommend a transition cement (ABC-PVC) for it I lost interest. This sweep elbow must be made of ABS (or CPVC I read elsewhere). I rather keep everything to good old PVC.
Anyway what do you guys think of this elbow?
