The answer is a water powered backup sump pump that runs off the reliable water supply that brings water to your home under pressure every single day. The best answer is the Basepump Water Powered Backup Sump Pump.
Basepump® Theory of Operation
- Basepump Ejector is mounted on the ceiling joist above the sump, unaffected by scale, corrosion, clogging, or debris.
- A PVC pipe with a screen on the end extends from the Ejector down into the sump.
- Separate outdoor discharge or shared indoor discharge installations may be used.
- A float is mounted in the sump pit above the normal high water mark. Your primary electric sump pump will handle all the normal pumping duties.
- When water rises higher than normal, the Basepump float in the sump is lifted and hydraulically activates the Basepump Ejector on the ceiling.
- Using an age-old principle, this creates a powerful suction force which causes the PVC pipe to act like a giant soda straw, drawing water up from the sump and ejecting it outdoors.
- As the water level falls, the float drops down and a pre-set timing control keeps the ejector running for about 30-45 seconds before shutting off the system. This allows a full pump-down of the sump, like an electric sump pump.
