Best Pump For Draining Pool: 10 Submersible Options Compared

#1 · Best Overall

1. Seesii 1HP Submersible Pump

• Dimensions: 6.18"L x 6.18"W x 12.24"H
• Material: Polypropylene (PP)
• Voltage: 120 V

Best for: Long-distance water transfer.

Why it ranks #1: Its listed 4,755 GPH flow and 36-foot lift suit substantial pool-water removal, and the product is explicitly described for pools.

A 36-foot lift sets the Seesii apart for pool draining where discharge must travel upward or farther from the pump. Its 1 HP motor is rated for up to 4,755 gallons per hour, pairing high stated flow with the headroom to route water to elevated areas.

The 36-foot maximum lift can help when the discharge point sits above the pool or farther away, while the 1 HP motor’s stated 4,755 GPH rate supports rapid bulk removal. A built-in filter blocks small debris and is described as reducing clogging, which can simplify upkeep during dirty-water jobs. The product listing also specifies a 23-foot hose, so its reach is a practical consideration when planning where the water will go.

Skip it if you want a stated shallow-water cutoff for unattended cover drainage; the Little Giant APCP-1700 specifies automatic activation and shutoff levels.

Choose the Seesii when pool water needs to move to a higher or more distant discharge point and high stated flow matters. Its 36-foot lift is the relevant boundary; plan hose routing around the listed 23-foot hose rather than assuming longer reach.

#2 · Low-Level Draining

2. AQUASTRONG 1 HP Sump Pump

• Dimensions: 6.3"L x 9.85"W x 11.03"H
• Material: Thermoplastic
• Voltage: 115 V AC

Best for: High-volume pool draining.

Why it ranks #2: The 4,500 GPH rating supports fast water removal, while its bottom-suction design is listed to drain down to 1/5 inch.

A 1 HP motor moves up to 4,500 gallons per hour at a five-foot lift, giving pool owners a high-flow option for substantial water removal. Its bottom-suction design also draws water down to one-fifth inch from the surface, a useful feature when you want to leave less standing water behind.

The stated 30-foot vertical lift supports routing discharge to a higher point, while the 11⁄4-inch NPT outlet and included 3⁄4-inch garden-hose adapter give you two listed connection options. Bottom suction reaches water down to one-fifth inch and handles solids up to one-fifth inch, helping with shallow residue and small debris. At 8.5 pounds, the thermoplastic pump is portable; plug it in to run and unplug it to stop.

Skip it if you need automatic start and stop on a pool cover; the Little Giant APCP-1700 lists activation at two inches of water.

For pool owners prioritizing high flow and shallow-water pickup, the AQUASTRONG offers a straightforward portable option. Check that its 11⁄4-inch NPT outlet or included garden-hose adapter suits your discharge setup, and account for the stated flow at five feet of lift.

#3 · Highest Capacity

3. Aeromixer 1 HP Transfer Pump

Best for: High-flow debris-tolerant transfer.

Why it ranks #3: Its listed 5,120 GPH is the highest flow figure here, and it can pass solids up to 1/4 inch for less-clear water.

A 5,120 GPH rating and ability to pass solids up to one-quarter inch give the Aeromixer a combination suited to moving substantial volumes of dirty water. Its 1 HP submersible design is described for pools, tanks, pits, and flooded yard areas, rather than clear water alone.

The 5,120 GPH stated flow supports bulk water transfer, while the one-quarter-inch solids capacity lets debris pass through rather than jam the pump, according to the listing. That combination can reduce concern about small solids during draining of a dirty pool cover or flooded area. Setup is described simply as submerging the pump and plugging it in. The supplied specifications do not list cord length or hose connections, so discharge planning needs those details established separately.

Skip it if you need a specified hose and cord for immediate poolside setup; the Little Giant APCP-1700 lists a 25-foot cord and hose adapter.

The Aeromixer suits buyers draining dirty pool water or covers who value high flow and passage of small solids. Its listing leaves cord and hose details unspecified, so confirm the discharge arrangement for your particular setup.

#4 · High-Lift Option

4. Lanchez 1/2 HP Sump Pump

• Dimensions: 6.3"L x 5.5"W x 11.02"H
• Material: Plastic
• Voltage: 115 V AC

Best for: Debris-aware pool draining.

Why it ranks #4: The 2,450 GPH pump is listed for swimming pools and lifts water up to 31 feet, with a side inlet and metal filter.

A side inlet paired with a metal filter helps keep debris and sediment away from the Lanchez pump’s internal parts, a practical distinction when pool water is not perfectly clean. Its 1/2 HP motor is rated for 2,450 GPH and a vertical lift of up to 31 feet.

The 31-foot lift gives pool owners flexibility to direct discharge upward, while the 2,450 GPH rating suits substantial water removal without the higher flow claims of 1 HP models. Thermoplastic construction is described as corrosion-resistant, and the side inlet with metal filter helps guard against debris entering the pump. The listed 10-foot cord is a key placement constraint, so locate the pump and outlet with that reach in mind.

Skip it if you need a longer listed power cord for poolside placement; the bokazi 1/2 HP pump specifies a 25-foot cord.

This Lanchez suits pool owners who want a debris-conscious inlet and a 31-foot lift for routing water upward. Its 10-foot cord is a meaningful setup boundary, so consider outlet location before choosing it for a pool-draining job.

#5

5. Tenzzola 1/3 HP Sump Pump

• Material: Plastic

Best for: Midrange pool-water removal.

Why it ranks #5: Its listed 2,400 GPH flow and 30-foot vertical lift make it a capable utility option, and the product is described for swimming pools.

A 1/3 HP motor rated for 2,400 GPH gives the Tenzzola a useful middle ground for pool draining and other water-transfer jobs. Its listed lift reaches 30 feet, while a side inlet and metal filter help limit debris and sediment entering the pump.

The 30-foot vertical lift supports discharge routing above the pump, and the 2,400 GPH rating provides a stated basis for planning water removal. At the bottom, the side inlet is described as preventing debris and sediment suction, while the metal filter blocks impurities; together, these features can reduce unwanted material reaching internal parts. Thermoplastic construction is listed as corrosion-resistant, making the material relevant when selecting a pump for wet utility work.

Skip it if you require a specified long cord for poolside reach; the AgiiMan 850GPH Pool Cover Pump lists a 25-foot power cord.

The Tenzzola is a fit for pool owners wanting a 2,400 GPH utility pump with a stated 30-foot lift and debris-conscious intake. The supplied specifications do not give cord length, so that setup detail remains a boundary.

#6

6. bokazi 1/2 HP Sump Pump

• Dimensions: 4.7"L x 9.6"W x 4.7"H
• Material: Plastic
• Voltage: 110 V AC

Best for: Long-cord utility draining.

Why it ranks #6: The 1,800 GPH pump is described for water removal and includes a 10-foot garden hose, though its stated lift is 24.5 feet.

A 25-foot power cord gives the bokazi pump more stated placement reach than its included 10-foot garden hose, a useful distinction when locating a pump near a pool. Its 1/2 HP motor is rated at 1,800 GPH and can lift water vertically up to 24.5 feet.

The 25-foot cord can help place the pump farther from an outlet, while the included 10-foot garden hose and adapter provide a specified discharge connection. A 24.5-foot maximum lift supports routing water upward, and the 1,800 GPH rating gives a defined flow figure for planning. The product is listed as a submersible utility pump for water removal, making it suitable to consider for pool draining as well as the stated flooded-basement use.

Skip it if you need a higher stated flow rate for faster bulk removal; the AQUASTRONG 1 HP Sump Pump lists 4,500 GPH at five feet of lift.

The bokazi suits pool owners who value a 25-foot power cord and a supplied garden hose for utility draining. Its 10-foot hose and 1,800 GPH rating define the practical limits for discharge distance and bulk-water pace.

#7

7. Green Expert 1/4HP Sump Pump

• Dimensions: 6.8"L x 6.8"W x 10.5"H
• Material: Plastic
• Voltage: 115 V

Best for: Portable emergency pool drainage.

Why it ranks #7: It is explicitly listed for pools and hot tubs, with 1,800 GPH flow and a 28-foot maximum head for moderate water-removal jobs.

At 3.3 kilograms and with a 1/4 HP motor rated for 1,800 GPH, the Green Expert combines a portable listed weight with a defined drainage rate. It is specified for pools and hot tubs as well as basement flooding, garden drainage, and other household water-management tasks.

The 1,800 GPH rating gives a concrete expectation for routine pool or hot-tub water removal, while the listed 28-foot maximum head supports routing discharge to a higher point. A 11⁄4-inch hose barb adapter and 3⁄4-inch garden-hose adapter are included, allowing two listed connection choices. The included lifting rope can help position or retrieve the 3.3-kilogram pump, a practical detail for handling it around a wet pool area.

Skip it if you need higher stated flow for bulk pool draining; the Aeromixer 1 HP Submersible Transfer Pump lists 5,120 GPH.

The Green Expert fits pool owners seeking a portable utility pump for measured draining, with adapters and a lifting rope included. Its 1,800 GPH rating is the main boundary when faster bulk water removal is the priority.

#8 · Automatic Cover Pump

8. Crestwave Automatic Cover Pump

• Dimensions: 8.58"L x 8.58"W x 3.23"H
• Material: Copper Motor
• Voltage: 115 V AC

Best for: Automatic shallow-cover pickup.

Why it ranks #8: Designed for pool-cover water, it automatically starts at 1.5 inches and shuts off at 0.39 inches; it is less suited to emptying a pool.

The Crestwave starts at 1.5 inches of water and shuts off at 0.39 inches, giving pool-cover owners a defined automatic draining cycle. Its low-profile, flying-disc form and heavy-duty base are described as stable and tip-resistant during operation.

Automatic switching between the listed 1.5-inch start and 0.39-inch shutoff levels reduces the need to monitor cover water constantly. The heavy-duty base and tip-resistant design support stable operation, while the 25-foot power cord offers a stated reach for placement. Two adapters are included for setup, although their sizes are not listed. The product is specified at 68 watts, a useful operating detail when planning its electrical connection.

Skip it if you need a stated gallons-per-hour rate to plan bulk pool draining; the Seesii 1HP Submersible Water Pump lists 4,755 GPH.

The Crestwave fits owners seeking automatic removal of shallow water from a pool cover, with a low-profile base and specified switching levels. Since no flow rate is supplied, it is less suited to buyers planning drainage by volume and time.

#9

9. Little Giant APCP-1700

• Dimensions: 12"L x 12"W x 8.25"H
• Material: Polypropylene (PP)
• Voltage: 115 V

Best for: Automatic pool-cover drainage.

Why it ranks #9: This 1,745 GPH model targets pool covers and activates at 2 inches, but its cover-pump purpose makes it a poor fit for emptying a pool.

Automatic operation is the Little Giant APCP-1700’s defining advantage: it starts when water reaches two inches and shuts off at one inch. That makes it specifically suited to removing accumulated water from pool covers without requiring the user to switch the pump on and off manually.

The automatic activation and shutoff levels support unattended cover-water removal within the listed one-to-two-inch range. A removable intake screen can be taken out for cleaning, maintenance, and airlock removal, making routine upkeep more direct. Its compact, weighted design is described as stable and portable, while the built-in handle helps with placement and removal. A 25-foot cord and included garden-hose adapter provide specified setup details for routing discharge.

Skip it if you need a high-flow pump for draining a full pool; the Aeromixer 1 HP transfer pump lists 5,120 GPH.

The APCP-1700 fits owners who need automatic removal of water from a pool cover, boat cover, or rooftop. Its listed switching range is the key boundary: this is a cover-water pump, not a high-flow full-pool drain.

#10

10. AgiiMan 850GPH Cover Pump

• Dimensions: 6.7"L x 4.5"W x 5.2"H
• Material: Acrylonitrile Butadiene Styrene (ABS)
• Voltage: 110 V

Best for: Compact pool-cover drainage.

Why it ranks #10: Its pool-cover pump design and listed 850 GPH flow are better suited to removing cover water than draining a swimming pool.

A 6.7-by-4.5-by-5.2-inch body makes the AgiiMan a compact option for above-ground pool-cover water removal. Its listed 850 GPH capacity suits a more modest drainage pace, while the included 16-foot hose and 25-foot power cord give the setup useful specified reach.

The 850 GPH rating places this pump in a different role from high-flow, 1 HP transfer models: it is a compact choice for managing water on an above-ground pool cover. The included 16-foot hose provides a specified discharge length, and the 25-foot power cord gives placement flexibility relative to an outlet. Three adapters are included, though the listing does not identify their sizes, so the connection details need to be checked against your setup.

Skip it if you need a stated high-flow rate for fast bulk removal; the AQUASTRONG 1 HP sump pump lists 4,500 GPH at five feet of lift.

The AgiiMan fits owners seeking a small pump for above-ground pool-cover water and who value the included hose and cord. Its 850 GPH rating sets a modest pace, and adapter sizes are not specified in the supplied listing.
