A 1 horsepower sump pump can move substantial water during heavy rain, snowmelt, or flooding. The WAYNE CDU1000 is best for an automatic basement installation, while the AQUASTRONG and FOTING models are better suited to portable water removal and shallow cleanup. The other WAYNE 1 HP model is an indoor-use option with a top-suction design. A 1/2 HP WAYNE pump is included as a lower-power alternative, not as a 1 HP match.
| Product | Best For | Listed Flow Rate |
|---|---|---|
| WAYNE CDU1000 | Automatic basement sump use | Up to 6,100 GPH |
| AQUASTRONG 1 HP | Portable drainage and shallow water removal | 4,500 GPH at 5 feet |
| WAYNE CDU1000ET | Indoor use and high water flow | Up to 6,100 GPH |
| FOTING 1 HP | Portable clean or dirty water removal | 4,600 GPH at 5 feet |
| WAYNE CDU800 1/2 HP | A lower-horsepower alternative | Up to 5,100 GPH |
WAYNE CDU1000 1 HP Sump Pump
Best for: Homeowners seeking a high-capacity pump with automatic operation in a basement sump pit. This model combines a 1 HP motor rated to pump up to 6,100 gallons per hour with an integrated vertical float switch for automatic on-and-off operation.
Its stainless steel motor housing and cast iron volute are designed for demanding sump applications. The vertical float design is described as space-saving, which may help when fitting a pump into a narrow pit. The listed product information also states a five-year warranty and assembly in the USA.
Consideration: The product’s maximum stated flow rate does not by itself show how much water it will move at a particular discharge height. Check your installation’s lift requirements before choosing.
AQUASTRONG 1 HP Portable Sump Pump
Best for: Buyers who need a portable pump for a basement window well, pool, pond, or hot tub. AQUASTRONG lists a flow rate of 4,500 GPH at 5 feet and a maximum vertical lift of 30 feet. Its bottom-suction design can remove water down to 1/5 inch from the surface and handle solids up to 1/5 inch.
The pump has a 10-foot power cord and includes a 1-1/4-inch NPT discharge, a 1-1/2-inch elbow adapter, and snap coupling adapters for several hose sizes.
Consideration: Operation is described as plug in to start and unplug to stop. Choose another option if you need an integrated automatic float switch.
WAYNE CDU1000ET 1 HP Sump Pump
Best for: Indoor basement installations that need high water-moving capacity and a top-suction design. The manufacturer lists a maximum rate of 6,100 GPH and describes the pump as suitable for heavy water flow from rain or snowmelt.
The motor housing and fasteners are corrosion-resistant stainless steel, and the volute is cast iron. The top-suction design is intended to reduce air-lock concerns and minimize clogging from debris at the bottom of the sump pit. The product information also says installation takes about 15 minutes and does not require drilling a weep hole.
Consideration: This model is specifically listed for indoor use only. Do not select it for an outdoor application based on its capacity alone.
FOTING 1 HP Clean Or Dirty Water Pump
Best for: Portable drainage where a pump may need to move clean or dirty water. FOTING lists a flow rate of 4,600 GPH at 5 feet and a maximum lift of 31 feet. It can remove water down to 1/5 inch and handle solids up to 1/5 inch, making it a candidate for tasks such as draining a pond, pool, or flooded window well.
The pump has a 10-foot power cord, thermoplastic housing, a removable bottom for cleaning, and a rounded handle. These features make it easier to carry and maintain than a pump intended to stay permanently in a sump pit.
Consideration: Its listed operation is plug in to start and unplug to stop, so it does not offer the automatic float-switch operation specified for the WAYNE CDU1000.
WAYNE CDU800 1/2 HP Alternative
Best for: Buyers comparing a lower-horsepower automatic sump pump with 1 HP options. This is a 1/2 HP model, not a 1 HP pump; its listed maximum flow is 5,100 GPH. It has an integrated vertical float switch and cast iron and corrosion-resistant steel construction.
The product information says its vertical float switch was tested to one million cycles. It may suit a buyer whose requirements call for this pump’s listed specifications rather than a 1 HP motor.
Consideration: Avoid this option if your purchase specifically requires a 1 HP pump. Horsepower and flow ratings should be compared against the needs of the actual sump system.
Buying Guide: How To Choose A 1 HP Sump Pump
Do you need an automatic sump pump?
For a pump intended to cycle as sump water rises, look for an integrated float switch. The WAYNE CDU1000 lists a vertical float switch and automatic on-and-off operation. AQUASTRONG and FOTING describe manual plug-in and unplug operation, so they are better suited to supervised, portable drainage than unattended automatic cycling.
How much water does the pump need to move?
Compare flow rates at the stated conditions. AQUASTRONG lists 4,500 GPH and FOTING lists 4,600 GPH at 5 feet, while the WAYNE models list maximum rates of up to 6,100 GPH or 5,100 GPH. These figures should not be treated as directly equivalent unless the pumping conditions match.
What lift height and water depth matter?
Vertical lift is the distance water must travel upward through the discharge line. AQUASTRONG lists a lift of up to 30 feet, and FOTING lists up to 31 feet. For shallow cleanup, both portable models state that they can remove water down to 1/5 inch. Confirm that the pump’s specifications suit your discharge setup.
Should you choose cast iron or thermoplastic?
The WAYNE options list cast iron and stainless or corrosion-resistant steel components for sump applications. AQUASTRONG and FOTING list thermoplastic housings and portable drainage uses. Choose based on the intended installation and the listed construction rather than assuming one material is best for every job.
