Why it matters
The 30-0040 splices into an existing 1-1/2 in PVC discharge with solvent-weld ends and unions, so the pump can be pulled later without cutting pipe. A 1/2 lb spring closes the flapper quickly to stop water hammer.
Zoeller rates it at 50 psi (115 ft of head) with a full-flow, non-clog design, and it can go in vertically or horizontally.
Who it's for, and who should skip it
Good fit if
- Permanent PVC discharges
- Owners who want to service the pump later
- Quieting a noisy system
Look elsewhere if
- Rubber-coupling installs
- 2 in lines
