This system adds one additional feature to System 4, the Sump Safety.  The Sump Safety is a device designed to restrict the flow from the drain tile into the sump.  Since flow through a 4-inch drain tile could theoretically exceed 200 gpm, even the capacity of System 4 could be exceeded.  The Sump Safety is designed to physically limit the flow to less than the capacity of the installed pumps.

Stats

  With Utility Power During Power Outage
Pumping Capacity (gpm)1 124 107
Pumping Time at 35 gpm (hours)2 No Limit 22.5

1 Pumping capacity is at the estimated operating point assuming 8 feet of lift is required.  See the Get Technical pages for details.

2 During a typical rainfall, continuous operation at 35 gpm would not be required, so pumping time would be significantly longer.
