For narrow pits you can mount the backup pump on an “L” bracket above the main pump. You will need to purchase the following items from a hardware store:

• “L” bracket at least six inches long (preferably one that will not rust)
• 2 stainless-steel hose clamps
• 1 stainless-steel screw (#8-32 x ¾”) with a matching washer & nut

Refer to your product manual for instructions on how to mount the backup pump above your primary pump.

An easier option is to purchase one of our combination systems when it is time to add a backup or replace your existing battery backup system. These systems come preassembled with check valves, a “Y” connector, and both a primary and backup pump. The compact design of our combo systems allow them to fit into most narrow pits.
