Spec Sheet   Install Manual

The SumpJet (Model SJ10) is a water powered back-up sump pump that will protect your basement in the case of a power outage. This unique product is powered by your municipal water supply and requires no electricity to operate! With a compact high efficiency design, The SumpJet removes 2 gallons of sump water per 1 gallon used. The SumpJet is fully automatic, arrives completely assembled, and comes backed with Liberty's standard 3 year warranty.

Having an alarm on your water powered backup pump is important. In the event of a main pump failure -- you want to know your backup pump has taken over and is operating.

The SJ10 pumping performance varies with inlet water source pressure and pumping head. See complete specifications and performance chart for expected flow rates.

The SJ10 requires an uninterrupted water source to operate. If you have a well pump, the SJ10 will not operate during power outages.
