The best 1/6 HP submersible pump depends on the job: the Green Expert is suited to routine household drainage, the Wayne is a heavy-duty multi-use option, and the 6699 Store SUB 1100 is designed for clean-water removal. For tankless water heater maintenance, choose the pump-and-kit bundle. A 1/4 HP model is also included as a higher-capacity alternative, not a 1/6 HP pump. Compare flow claims, lift height, hose connections, and the type of water each model is intended to handle.

Green Expert 1/6 HP Utility Pump

Best for: Homeowners who need a compact pump for several everyday water-removal tasks. Its listed uses include flooded basements, pools, hot tubs, garages, yards, and window wells.
The pump has a 1/6 HP motor and a stated flow of up to 1,400 gallons per hour. Its oil-free motor and corrosion-resistant thermoplastic housing are designed for clean operation, while the compact body is intended to make carrying and placement easier. It was selected for its combination of stated capacity and broad residential use cases.
Limitation: The supplied details do not state a maximum lift height or minimum water level, so check those requirements for your drainage setup before choosing it.
WAYNE RUP160 1/6 HP Pump

Best for: Buyers looking for a multi-use pump with a high stated flow rate. The WAYNE RUP160 is a 1/6 HP oil-free pump rated for up to 3,100 gallons per hour and is described as suitable for indoor and outdoor applications.
Its sealed, corrosion-resistant thermoplastic construction is designed for submersible use. The pump can remove water down to 3/8 inch, which gives shoppers a specific residual-water figure to compare with other models. It includes a 1-1/4-inch discharge and a 3/4-inch garden hose adapter.
Limitation: The listed minimum water level is 3/8 inch, so it is not specified to leave a surface as nearly dry as pumps rated to 1/12 inch.
6699 Store SUB 1100 Utility Pump

Best for: Clean-water drainage where a low remaining water level and straightforward hose setup matter. This portable 1/6 HP pump is listed for uses such as removing water from a basement, pool, or tankless heater flushing setup.
The product information states a flow of up to 1,100 gallons per hour and says it can remove water down to 1/12 inch. A screened inlet helps keep large solids out. Included adapters connect to a 3/4-inch garden hose or a 1-inch PVC lay-flat hose, and the pump has a 10-foot power cord.
Limitation: It is not suitable for dirty water or expandable hoses. Choose another option if the water contains debris or sediment.
Tankless Water Heater Flushing Kit

Best for: People who specifically need equipment to flush a tankless water heater. This bundle includes a 1/6 HP pump, two 6-foot PVC hoses, a 3-gallon pail, adapters, washers, and a lid opener.
The pump is listed with a maximum lift height of 16.5 feet and a flow rate of 1,100 gallons per hour. The kit instructions describe mixing one gallon of vinegar or biodegradable cleaner with one gallon of water for flushing. It was selected because the included hoses and bucket make it more task-specific than a standalone utility pump.
Limitation: Cleaning solution is not included. Confirm that the kit’s supplied connections suit the heater’s isolation valves before starting the maintenance task.
6699 Store 1/4 HP Transfer Pump

Best for: Buyers willing to consider a more powerful alternative to a 1/6 HP pump. This model has a 1/4 HP motor, a stated flow of up to 1,500 gallons per hour, and a maximum lift height of 23 feet.
It includes a 10-foot power cord, a 1-inch discharge adapter, and a 3/4-inch garden hose adapter. The bottom screen is described as filtering solids up to 1/5 inch thick, and the product information says it can remove water down to 1/12 inch. These details make it a useful comparison when a job calls for more lift or flow than some 1/6 HP models list.
Limitation: This is not a 1/6 HP pump. Choose it only if the higher motor rating fits your needs and you do not require a strict 1/6 HP model.
Buying Guide: How To Choose A 1/6 HP Submersible Pump
What flow rate and lift height do you need?
Flow rate, measured in gallons per hour (GPH), indicates the amount of water a pump is stated to move under its specified conditions. Lift height is the vertical distance the pump is rated to move water. Compare both figures with your drainage route. A high flow claim alone does not tell you how quickly a pump will work at a particular height.
Is the water clean or dirty?
Check the product’s water-use limitations and inlet design. The SUB 1100 is explicitly not suitable for dirty water, while the 1/4 HP model lists a screen that handles solids up to 1/5 inch. Do not assume that a screened inlet makes a pump appropriate for muddy or debris-filled water.
How low must the pump drain?
Compare the stated minimum water level. The SUB 1100 and 1/4 HP pump list removal down to 1/12 inch; the WAYNE lists removal down to 3/8 inch. The Green Expert listing does not provide a minimum level in the supplied details. A pump may still leave water that requires separate cleanup.
Which hose connection is compatible?
Match the included adapter to the hose you plan to use. The SUB 1100 includes 3/4-inch garden-hose and 1-inch PVC lay-flat hose adapters, while the WAYNE has a 1-1/4-inch discharge and a 3/4-inch garden-hose adapter. Review hose restrictions as well as connection size.
Frequently Asked Questions
What is a 1/6 HP submersible pump used for?
It is used to move water from areas such as basements, pools, garages, and window wells. Some 1/6 HP pumps are also included in kits for tankless water heater flushing.
Can these pumps remove dirty or muddy water?
Not all of them. The SUB 1100 is expressly described as unsuitable for dirty water. Check each model’s inlet and debris specifications before pumping water with solids.
Does a higher GPH rating always mean faster drainage?
No. Flow at the actual site can depend on the lift height and hose arrangement. Compare the stated flow and lift specifications together.
Should I choose a pump that drains to 1/12 inch?
Choose one with that specification if minimizing the remaining water is important. The product details list 1/12 inch for the SUB 1100 and the 1/4 HP pump.
Is a tankless water heater flushing kit different from a utility pump?
Yes. The flushing kit bundles a pump with hoses, a pail, adapters, and other listed accessories for heater maintenance. A standalone utility pump may require you to source suitable accessories separately.
