Decide What Can Remain
A lower residual water level reduces the final cleanup. It does not mean the floor will be completely dry.
LOW-LEVEL DRAINAGE
Low-Level Utility Pumps
For the final stage of clean-water removal. Compare residual-water levels, starting conditions and control options before choosing a model.

Before You Choose
Before You Choose
Use these points to compare the water, installation and operating requirements before choosing a model.
A lower residual water level reduces final cleanup but does not leave the floor completely dry. Check starting level, stopping method and the selected model’s operating instructions.
Check the Starting Level
The water needed to start pumping can differ from the level a running pump can drain down to.
Check How It Stops
Manual operation and automatic level controls behave differently. Use the selected model’s instructions.
Explore the Applications
Explore the final stage of pool, tank and clean-water floor drainage. Remove debris before considering a clean-water low-level model.
Key Applications
Where these families may fit within their published limits.
Application suitability depends on the liquid, solids, required duty point, installation/control method and exact product configuration.
Pool & spa drainage
Low-level finishing where water chemistry and debris remain within the selected clean-water model limits.
Explore applications ↗Tank & container emptying
Choose by required transfer flow and the residual-water level that may remain at the end.
Explore applications ↗Basement & flood drainage
Use low-level clean-water families for final cleanup after bulk floodwater and debris have been removed.
Explore applications ↗Drainage
Shallow clean-water cleanup where residual-water target and control method are part of the selection.

Questions to Check Before You Choose
Will a low-level pump leave the floor dry?
No. The listed clean-water models leave a residual water level of 7 or 10 mm under the applicable conditions. Some final cleanup may still be needed.
Does a 7 mm residual level mean it starts at 7 mm?
No. Residual level, starting level and automatic switching levels are different values. Check the selected model and operating method.
