INSTALLATION
In this installation, if the Primary Sump Pump (PSP) does not have a check valve installed below the wye, you MUST
install a check valve for the PSP as shown. This prevents backflow of water into the sump from the battery backup
system.
Check Valve Flapper(s) must swing away and flow arrow(s) must point away from the pump being protected.
The water level when the switch shuts off must be above the BBU pump intake.
