Why it matters
The CV-150 uses a spring-loaded flapper that closes before the water column slams it shut, which removes the bang a standard swing check valve makes at the end of each cycle.
Its clear body shows water moving and makes a clog easy to spot. It comes with Buna-N rubber couplings and stainless steel clamps for 1-1/2 in Schedule 40 pipe and fits in a 5-1/8 in gap.
Who it's for, and who should skip it
Good fit if
- Noisy sump pumps
- 1-1/2 in PVC discharges
- DIY replacements
Look elsewhere if
- 2 in or 1-1/4 in lines without adapters
- Sewage lines needing a full-port valve
Pros and cons
Pros
- Silent spring flapper
- Clear body
- Couplings and clamps included
Cons
- ABS plastic body
- Fits 1-1/2 in pipe only
- Some head loss from the spring
Limitations to weigh
- Install it with the flow arrow pointing up and away from the pump.
- Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
