Jeff Beck Posted October 15, 2011 Report Share Posted October 15, 2011 From yesterday's inspection: Is this back flow valve located in the correct position? There is a battery powered back-up pump on top of the main sump pump but only the main is protected by the back flow valve. When the main pump is manually activated it drains the crock. When the main shuts off, the crock refills through the back-up pump. The picture doesn't show it but both pumps are submerged with ample room to spare when the crock is refilled through the back-up pump.

Thanks in advance for your advice and help Jeff Quote Link to comment Share on other sites More sharing options...

Each pump should have its own backflow valve so that one can't pump water into the other. Quote Link to comment Share on other sites More sharing options...

I can't even tell you the last time I found a backup pump in my area. Glad you posted Jim! Quote Link to comment Share on other sites More sharing options...

kurt Posted October 16, 2011 Report Share Posted October 16, 2011 Those plastic POS's should be relocated to the waste bin; it's a plastic pump on a 12 volt battery. Plumbers around here love them because it's a high margin quick turnaround job. I hate plastic pumps; I find about 50 a year that don't work. Sumpro UPS with a Zoeller or Hydramatic pump. If you live someplace that needs a pump system, it's the way to go. Quote Link to comment Share on other sites More sharing options...
