Stainless-steel construction and operating limits
Water rises. The float responds.
Automatic water-level switching
Supervised manual drainage
Manual mode does not stop automatically. Stay with the pump and disconnect power before it runs dry.
Match the hose. Protect the flow.
Hose diameter affects flow. Smaller hoses, including standard garden hoses, restrict output. A larger-diameter line allows more flow under the same conditions. The listed 4,000 GPH maximum uses a 1-1/2 in discharge hose in a horizontal setup; lift, hose length and fittings also reduce actual flow.

FSP1100DWB questions, answered.
Is this a low-water automatic utility pump?
No. The current listing shows automatic start above approximately 20 in and automatic stop below approximately 6 in in the illustrated float setup. Actual switching levels depend on the tether length and installation. Use a basin that gives the tethered float room to move. For lower water, supervised manual operation can drain to approximately 2 in; it does not stop automatically.
How do I switch to manual operation?
Secure the blue float in the side slot shown in the operation diagram. The pump then continues running while powered, even as the water level falls. Stay with the pump and disconnect power before it runs dry. Never leave manual operation unattended.
Why is my flow lower than 4,000 GPH?
Check discharge-hose diameter, hose length, vertical lift, bends and fittings. The listed maximum flow uses a 1-1/2 in hose in a horizontal setup. Smaller hoses, including garden hoses, restrict flow. Remove kinks and obstructions and keep the inlet clear. Maximum flow and maximum head are separate limits, not simultaneous output.
What basin size and water conditions does it need?
The current listing shows a minimum 16 × 16 in pit footprint, but the entire float travel path must also remain clear of walls, hoses and debris. It handles clean and dirty water with solids up to the manual-listed 35 mm. Water must stay at or below 95°F / 35°C. It is not for sewage, corrosive or flammable liquids, or continuous pond circulation.
Can I use a threaded garden hose?
Yes, the current listing includes a 3/4 in GHT garden-hose route and a stepped multi-hose adapter. Garden hoses restrict output compared with a wider discharge hose. Match the exact thread or hose inner diameter, and follow only the cut marks shown for the selected connection. G and NPT threads are not interchangeable. Hose and clamps are not included.

Safe use & operating limits
Use a properly grounded GFCI outlet. Keep power connections dry and lift the pump by its handle or supplied rope, never the power cable. Keep the float clear and the discharge hose free of kinks.
Never operate with people in the water. Not for flammable, corrosive or heated liquids; water must not exceed 95°F / 35°C. Do not use for continuous pond circulation. Manual hold-on does not stop automatically; disconnect power before dry running.
