WAYNE 1 HP Submersible Sump Pump - Heavy Duty Basement Pump

In this review of the WAYNE 1 HP CDU1000 submersible sump pump, the bottom line is simple: this is a heavy duty indoor sump pump for homeowners who need dependable, high-capacity performance during heavy rain or rapid snow melt. The single biggest reason to buy is the pump's combination of robust construction and effective top suction design that reduces clogging while moving thousands of gallons per hour, so a finished basement or utility area is protected without constant maintenance.

Key Features

• High flow capacity: Can move up to 6,100 gallons per hour in heavy flow conditions and 5,400 gph at 10 ft of discharge lift, giving strong flood protection when it matters most.
• Rugged construction: Corrosion-resistant stainless steel motor housing and fasteners combined with a cast-iron volute provide long life in demanding sump applications.
• Top suction design: The elevated inlet helps filter debris and minimizes clogging from sediment in the bottom of the pit for more reliable operation.
• Integrated float switch: The vertical float switch is built in for automatic on/off operation without complex external wiring or adjustments.
• Code-friendly discharge: 1-1/2 NPT discharge fits common plumbing and helps meet building code requirements.
• Assembled in the USA: Built with domestic and foreign parts and backed by a 5 year warranty for quiet, dependable performance.

Who It's For

The WAYNE CDU1000 is aimed at homeowners with finished basements or mechanical rooms who need a powerful, reliable indoor sump pump for frequent heavy runoff or sudden inflows. It suits users who prefer a rugged metal construction over lighter plastic pumps and who value a pump that handles debris better because of the top suction design.

Homeowners who need a fully submersible pump for small-diameter pits under 11 in or require an outdoor-rated unit should look elsewhere; this model is intended for indoor use only and is designed for 11 in diameter pits and larger.
