Liberty’s SumpJet: The Ultimate Failsafe Sump Pump

Tom

Sump pumps remove excess water, generally from basement-level sump pits. Water levels tend to be at their highest during storms and periods of heavy rainfall — the times during which power outages are most likely to occur. Almost any sump pump requires electricity to operate, so inopportune power failures can lead to major flooding and property damage.

 

Battery-powered backup sump pumps offer the most common solution, generally operating with power provided by 12-volt, deep-cycle batteries. While these systems can offer sufficient backup power during many storms, their batteries normally only have enough capacity to operate for several hours. This may not be enough to prevent flooding caused by major storms that result in an extended loss of power.

 

Liberty’s SJ10 (and SJ10A alarm model) SumpJet back-up sump pump system needs no electrical power to function and uses no battery, making it perhaps the only way to stop flooding caused by severe tropical storms. Instead of relying on a battery, the SumpJet generates energy from water pressure. Connected to a water supply via a 3/4” push-fit connection, the pump includes a float that opens a check valve when water approaches dangerous levels. The check valve allows municipal water into the pump in order to provide power. The pump can remove about two gallons of flood water for every gallon of municipal water. Incoming water pressure must be between 20 and 100 psi. Well-water systems generally cannot be used to power the SumpJet because their pumps will not usually be able to operate during power failures.

    Just curious if your power is down for long periods of time during storms, would this result in a very high water bill?

      Hi Garth. For the Liberty SumpJet (SKU: SJ10), your utility bill would depend on your system design, utility rate, and length of power outage. From our description we state that it removes roughly 2 gallons of water for each 1 gallon lost based off of a 5′ lift. With that knowledge you can do a rough calculation of the water accumulation you would gather over ‘x’ amount of hours. Divide that by two and multiply it by utility cost per gallon for water from your municipality. If your system differs from a 5′ lift, you should really reach out to Liberty Pumps for a better idea and adjust your calculation in accordance. Here is the number for Liberty Pumps for more clarification, since it is a technical question by nature: 1-800-543-2550
