Had a moment of panic when my pump lost suction mid-feed, but swapping in these valves with the diaphragm fixed it perfectly. They click into the flange body easily and hold a strong seal through multiple sessions. Just wish I'd ordered the 4-pack sooner.

These little valves saved my pump's suction completely — it felt like a brand-new machine the second I swapped them in. The four-pack is perfect since I can keep a set at work and home, and they fit my existing flange bodies without any fiddling.
