How to buy the best gas-powered water pump for you

Gas-Powered vs. Electric?

Gas-powered water pumps offer portability necessary for outdoor work while providing much higher flow rates for more industrial applications. A gas water pump can move a huge volume of water (up to 160 gallons per minute for a typical 2” model), so it’s used to drain a pool, empty a flooded basement, pump out a flooded trench, fill or empty a water storage tank or reservoir or irrigate a field. However, gas water pumps can only be used outdoors because the engines generate carbon monoxide. And Stronger means noisier, all gas-powered water pumps have higher decibel ratings than comparable electric water pumps.

Electric water pumps must have safety features necessary when working near water. Though limited in overall power, electric water pumps can be used indoors or outdoors and are quieter than gas-powered water pumps.

Clean Vs. Trash?

For most domestic users, a clean water pump will be more sufficient. As the name suggests, these pumps are suitable for water sources that don’t contain any corrosive liquids or medium to large pieces of debris. Ideally used with well-maintained ponds and fountains, flooded areas and large water transfers, a clean water pump will perform to a high standard, providing the water source isn’t contaminated.

A trash pump works in the same way as a clean water pump, but it has a thicker impeller vane and a larger volute discharge opening to pump large amounts of water that have solids. Solids in water are things such as sludge, mud, twigs, and leaves. Trash pumps are most commonly used at construction sites where after digging for the foundation water comes up the surface and cleaning pond sludge. We recommend you use a trash pump (or a semi-trash pump) to pump any source of water that contains even a bit debris or sand.

How many “Inch”?

Gas water pumps are available in 1”, 2”, 3” 4″, 6″, 8″, 10″ and 12″ sizes with maximum capacity up to 6300 GPM. But if you are choosing a trash pump for home use, select from 1” – 3” models. 2” pump is by far the most common size of gas-powered water transfer pump in use today.

Gallons Per Minute (GPM)

A gas-powered water pump’s GPM rating refers to the water flow during one minute of operation. The higher the GPM, the better the performance. When choosing the best gas-powered water pump, you should look more at GPM more than at horsepower. Most water pumps are rated by GPM, but are also rated by horsepower. And a higher horsepower does not mean a higher GPM.

Run Time

When you’re confronted by a marathon pumping job, a gas-powered water pump with a larger fuel tank will give you more hours of continuous pumping without refueling. A typical gas water pump has a fuel tank around 1 gallon that will provide approximately 2-3 hours of continuous pumping. There is a model from NorthStar which is built with a large fuel tank that can provide more than 10 hours of continuous pumping without the need to refuel – we are talking about the NorthStar Self-Priming Extended Run Semi-Trash Water Pump.

4. Earthquake WP4310 1-inch Water Pump

If you’re looking for a convenient gas-powered water pump that can provide the power you need, this little Earthquake WP4310 1-inch Water Pump is a perfect choice.

Earthquake WP4310 1-inch Water Pump | By getearthquake.com

This pump is mainly designed for clear water but will handle some sand and dirt, if the job calls for it. It features a high-performance 43cc Viper 2-cycle engine that delivers around 38 gallons of water per minute with a 23 feet suction lift. This small engine is used in EarthQuake’s Mini Gas Tiller/Cultivator which is one of the best-selling and top-rated tillers & cultivators on the market.

This gas-powered water pump is small and lightweight. It can be easily stored on the shelves in your garden sheds. However, the priming is a bit of a hassle. If you start with the pump near the input water level, you can fill the prime tank once and it will start moving water within 30 seconds. If you start with the pump uphill from the source, it takes a long time to prime. And the prime tank may empty as you fill it since the water is flowing out the inlet hose into the water source. So it’s best to start it just barely above the source.

Overall, the Earthquake 4310 is difficult to start but once started it works very well. And Earthquake gives you a generous 5-year residential and 90-day commercial warranty. If you are looking for a lightweight, high volume, very portable, inexpensive water pump, this pump is an excellent choice.

6. Honda WX15TA Water Pump


  • 1.5-inch clean water pump, 74 GPM
  • Durable 49cc Honda GXH50 4-stroke engine uses regular gasoline–no need to mix oil and gas

  • Incredibly quiet & virtually smoke-free
  • 2-Year Residential Warranty & 1-Year Commercial Warranty

This another pump from Honda is very small and lightweight. It’s made with quality and reliability in mind. It’s a bit more expensive than other comparable water pumps but we think it’s worth it. One of the quietest gas-powered water pumps you can buy.

This Honda WX15TA uses their own Honda GXH50 Engine. This hand-held engine is a 49.0 cm³ mini 4-stroke overhead cam petrol engine manufactured by Honda. It’s widely used for commercially produced mini tillers, water pumps, hedge cutters, pressure washers, and strimmers.

The size and weight of the GXH50 were reduced through the use of an oil-immersed timing belt overhead-cam configuration that makes it possible to incorporate the valve train into the oil reservoir. This results in an overall weight comparable to that of a two-stroke engine and an unparalleled power-to-weight ratio of 0.18kW/kg. GXH50’s four-stroke technology uses a unique rotary slinger pumping lubrication system, allowing it to be operated or stored in any position, and providing for low noise and vibration to minimize operator fatigue.

The Honda WX10TA is EPA & CARB compliant and weighs only 20 pounds. You get a 1-year commercial warranty or a 2-year consumer warranty depending on how you’re using it. Not only is the pump powerful, but you also get a suction hose, strainer, and garden hose adapter.
