Description
Little Giant 6-CIA-RFS Big John Automatic Submersible Sump Pump
Cast iron, oil filled, and it runs itself.
The Little Giant 6-CIA-RFS Big John is a 1/3 HP cast iron sump pump that moves up to 2760 GPH and switches itself on and off with a piggyback mechanical float, so it can be left to manage a pit, a pool vault, or a chronically wet equipment pad without anyone watching it. The oil filled cast iron motor housing lubricates the motor for life and pulls heat away during long runs, and a non-clog vortex impeller passes the grit that stops lesser pumps. Discharge is 1-1/2 in FNPT, and the unit is cCSAus listed.
Why PST Customers Pick This
Piggyback Float Switch
The mechanical float turns the pump on around 9-1/2 to 11-1/2 in of water and shuts it off near 1 to 4 in. Unplug the float and the pump runs manually.
Cast Iron And Oil Filled
The epoxy coated cast iron housing is oil filled for lifetime lubrication and heat dissipation, which is why these pumps last through years of duty cycles.
Non-Clog Vortex Impeller
The vortex design lets solids pass instead of wedging against the impeller, so silt and small debris do not shut the pump down.
1-1/2 in FNPT Discharge
Threads straight into standard rigid pipe or a hose adapter, so the discharge can be plumbed permanently rather than laid loose across the yard.
Mechanical Shaft Seal
Stainless spring, nitrile parts, and carbon and ceramic faces keep water out of the motor cavity where a cheaper seal would let it in.
cCSAus Listed
Safety certified for use in the United States and Canada, and rated for liquid up to 140 degrees F.
Electrical Safety
Use a dedicated GFCI protected circuit and never splice or shorten the power cord. Around pool equipment, NEC 680 bonding and grounding rules apply. Have an electrician confirm the circuit before the pump is put into service.

Frequently Asked Questions
What does the piggyback float switch do?
The pump plugs into the back of the float switch, and the float switch plugs into the wall. When water lifts the float, the pump runs. Unplug the pump from the float and plug it straight into the outlet to run it manually.
Is this a pool cover pump?
No. A cover pump lays flat and sips a shallow puddle. The 6-CIA-RFS is a sump pump that needs several inches of water to cycle, so it belongs in a pit, vault, or basin, not on a cover.
Why cast iron instead of thermoplastic?
Cast iron carries heat away from the motor, which is what matters when the pump cycles all night during a wet stretch. Thermoplastic sump pumps run hotter and generally have shorter service lives.
Can I hard pipe the discharge?
Yes. The 1-1/2 in FNPT discharge accepts standard threaded pipe. Install a check valve on the vertical run so the column of water does not fall back into the basin every time the pump shuts off.
