Overview
The SumpJet is a water powered backup sump pump from Liberty Pumps that runs off household water pressure instead of electricity, intended as an emergency backup rather than a primary pump.
Because it draws its power from the home's water supply line rather than a battery or the electrical grid, it is built to keep working through a power outage, a scenario a primary electric sump pump cannot cover on its own. The listing gives no horsepower or GPH figures, since output on this style of pump depends on incoming water pressure and volume rather than a motor rating.
- Water powered, no electricity required
- Accepts 20 to 100 psi inlet pressure
- Fully automatic operation
- Compact, fully-assembled design
Who it's for
Suits homeowners who already run an electric primary sump pump and want a no-power backup for storms and outages, rather than someone shopping for their only sump pump.
Pros and cons
- Works during a power outage since it needs no electricity
- Fully assembled, no motor to wire
- Accepts a wide 20 to 100 psi supply range
- No HP or GPH figures given, so output depends on your water pressure
- Requires an active, pressurized water supply to function
Performance notes
It runs on incoming household water pressure between 20 and 100 psi to drive the unit, so it needs no battery and keeps working as long as the water supply itself stays pressurized. It is described as fully automatic and fully assembled, so setup is largely plumbing it into an existing pit and supply line.
