Additional Info
Why are check valves necessary?
- Installed on sump pump discharge pipes to keep water from returning to the sump pit when the pump stops
- Keeps flooding water from entering the building through the discharge pipe
How do check valves work?
- While the pump is running the flapper in the check valve opens and lets the water out
- When the pump stops, the water above the check valve rushes back down and slams the flapper closed
- This keeps the water from re-entering the sump pit – it also makes a loud and annoying clunking noise!
Major improvement: the klunkless check valve
- Has a large silencing air chamber that absorbs the sound of the returning water
- Reduces the noise when the pump stops
- Don’t be awakened on rainy nights by a clunking noise every time the sump pump stops!
