Wayne Water Systems CDU1000 Submersible Sump Pump 1 Hp

Product Description

The WAYNE WATER SYSTEMS CDU1000 is a 1 HP submersible sump pump built for residential and light commercial sump basin applications. The motor housing features stainless steel fasteners and an epoxy-coated steel construction, while the volute is cast iron for long-term durability. An oil-filled, thermally protected motor guards against overheating during extended run cycles. The reinforced polycarbonate impeller delivers flow rates up to 4600 GPH at 0 feet of head. A vertical float switch with Float Guard prevents switch hang-ups, and the top suction design reduces debris ingestion and minimizes clogging. The 1-1/2 inch NPT discharge and cast iron base simplify drop-in installation.

The CDU1000 is suited for residential sump pits measuring 11 inches in diameter or larger. It is a common choice for basement water management systems where reliable automatic operation is required. The top suction inlet, vertical switch, and carry handle make repositioning and servicing straightforward. Licensed plumbers and general contractors typically install this unit as a primary or replacement sump pump in new construction and retrofit projects alike.

Key Features

• 1 HP oil-filled motor with thermal overload protection prevents burnout during prolonged operation
• Cast iron volute and base provide impact resistance and long service life
• Stainless steel motor housing fasteners resist corrosion in wet sump environments
• Top suction design filters debris and minimizes clogging at the impeller
• Float Guard on the vertical switch prevents float hang-ups and false cycling
• 1-1/2 inch NPT discharge allows installation without plumbing modifications
• Easy-carry handle simplifies transport and repositioning in the basin

Compatibility

Designed as an OEM-style replacement or direct installation submersible sump pump for residential sump basins 11 inches in diameter or larger with a 1-1/2 inch NPT discharge configuration.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Disconnect power to the sump basin circuit at the breaker before lowering the pump into the pit or making any discharge connections. Verify the basin diameter is 11 inches or greater before installation to ensure proper float travel. Do not run the pump dry, as sustained operation without water will damage the motor.
