Our challenge is that we have a great deal of water in the basement for about 2 weeks each Spring, then none the rest of the year. Hence the non-electrical water pressure driven backup system mentioned above will not work because it cannot pump out the water fast enough.John Halamkahttps://www.blogger.com/profile/04550236129132159307noreply@blogger.comtag:blogger.com,1999:blog-4384692836709903146.post-43713952310335803222010-04-17T12:22:03.477-07:002010-04-17T12:22:03.477-07:00This a very ingenious design.

After wiring two new deep discharge 12v batteries in series to get to its 24v battery voltage I use that inverter to power a second full sized pump that discharges on the opposite side of the house from the primary. To keep it secondary I just elevated the pump on a pair of bricks keeping the pumps float switch from triggering the pump unless the depth in the pit gets to deep. Both pumps could be running in this configuration if needed.Anonymousnoreply@blogger.com
