WPA3 / CB1500-AVB Backup Pump Operation
When water in your basement sump rises above the normal control range provided by your primary sump pump, your backup pump automatically starts pumping until the sump water is reduced sufficiently to lower it’s float below the trigger level:
Excess rising water in your basement sump lifts the backup pump Float
The backup pump float activates a Hydraulic Valve on the pump unit that allows city water to run through the Ejector.
Each gallon of city water flow through the backup pump ejector creates sufficient suction to pull 2 gallons of water from your sump up the suction tube.
A Check Valve on the pump body prevents water from returning back down into your sump.
The 2 gallons of sump water mix with the 1 gallon of city water as they discharge together out of the backup pump ejector into the discharge pipe and out of your basement.

WPA3 / CB1500-AVB Water Powered Backup Sump Pump Installation
The Basementsaver WPA3 and Basepump CB1500-AVB both come with Fully-Illustrated, Step-By-Step, Installation Instructions and may be easily installed by any homeowner with moderate DIY capability and a few common tools. The Basepump video below presents a WP1 /RB750 installation, and your WPA3 / CB1500-AVB installation will be similar, but with larger pipes and fittings.
The WP3-DCV1 / CB1500-DCV1 backup pump Ejector unit with DCV installs on a rafter in your basement ceiling, above your sump pit, with a vertical suction tube running down from the pump body into your sump. A hydraulic float is attached to the suction tube inside your sump, above the level of the water surface that is normally maintained by your primary sump pump.
Water Power is provided by permanently connecting a pipe from your city water supply into the pump unit, and sump water is discharged into the discharge pipe exiting to the outside of your home.
You MUST provide the WPA3 / CB1500-AVB unit with a dedicated discharge pipe.
You must NOT allow the WPA3 / CB1500-AVB to share the discharge pipe for your primary sump pump, or water coming from the primary sump pump will leak into your basement via the AVB!
