A.y. Mcdonald 6190-166 Vertical Piggyback Float Switch

Product Description

The A.Y. McDonald 6190-166 is a vertical piggyback float switch designed for automatic sump pump and water level control applications. The piggyback plug design allows the switch to be wired in series with a pump's power cord, enabling automatic on/off operation based on water level without the need for a separate control panel. Operating at 115 volts, the unit includes a 10-foot cord that provides flexibility for positioning the float at the correct activation depth. Licensed plumbers and pump service technicians typically install this switch as a replacement or upgrade on residential sump and effluent pump systems.

This float switch is suited for residential sump pit installations where a vertically actuated float is required. The vertical orientation means the switch activates and deactivates through an up-and-down float movement, making it appropriate for pits with limited horizontal clearance. The 10-foot cord length accommodates most standard residential sump pit depths and allows the installer to route wiring to the pump's outlet without extension. It is also used in sewage and effluent pump applications where automatic level control is needed.

Key Features

• Piggyback plug design allows direct series connection with pump power cord for automatic operation
• Vertical float actuation suits pits with limited horizontal space
• 10-foot cord provides installation flexibility for depth positioning and wiring routing
• 115-volt rating compatible with standard single-phase residential pump circuits
• Functions as a standalone replacement switch without requiring a separate control panel

Compatibility

Designed as an OEM-style replacement vertical piggyback float switch for residential sump, effluent, and sewage pump systems requiring 115-volt automatic level control.

Installation Notes

Installation should be performed by a licensed plumber or pump technician familiar with sump and effluent system wiring. Disconnect power to the pump circuit at the breaker before handling any wiring or replacing the float switch. The float must be positioned at the correct activation height within the pit to achieve the desired pump-on and pump-off water levels. Follow applicable local plumbing codes and the pump manufacturer's wiring instructions when connecting the piggyback plug.
