Pros
- 2 in valve and ports keep flow loss down with bigger pumps
- Seven-position top-mount valve: backwash with one lever
- Laterals fold on a ball joint, so the underdrain lifts out for service
Cons
- One-year parts-only warranty on the online (W3) version; dealer-sold versions get longer cover
- Sand passes coarser dirt than cartridge or D.E. filters, so water is less polished
- Backwashing dumps pool water to waste each time
