Lift Station Floats

A float switch is a level-sensing device that rises and falls with liquid levels in a lift station, triggering pumps to turn on or off at set points. Float balls, often with integrated magnets or threaded connections, attach to switches or control cables to automate pump activation, preventing overflows and dry-running conditions in wastewater and sump systems.

Septic and lift station systems commonly use three floats to control different functions: a low-level float that prevents the pump from running dry, a high-level (on) float that activates the pump once liquid reaches a set threshold, and an alarm float that signals an emergency high-level condition requiring immediate attention.

Most durable lift station floats use 304 or 316 stainless steel rather than plastic. Stainless steel resists corrosion from wastewater, chemicals, and moisture, withstands pressure fluctuations, and maintains structural integrity over long service periods, making it the preferred material for demanding municipal and industrial lift station applications.

Yes, float balls can be fully customized with specific thread specifications, through-tube diameters, magnet placement, and finishes (matte, brushed, or polished) to fit unique lift station tank geometries, existing control cables, and mounting hardware, ensuring seamless integration without modifying existing infrastructure.

The optimal shape depends on tank space and mounting method. Round floats suit compact installations and rod-mounted switches, while oblong floats provide greater buoyancy and stability in larger tanks or turbulent flow conditions. Both shapes are available with custom threads and through-tube fittings for lift station applications.

Pressure testing is recommended for floats used in sealed or high-pressure lift station environments to confirm they remain watertight and structurally sound under operating conditions. Manufacturers can pressure test each float to customer-specified tolerances, reducing the risk of failure, leakage, or inaccurate level readings in critical systems.
