Much like our heart pumps blood around our body to keep us alive, a sprinkler pump delivers water to your lawn and garden to help it flourish. But not all sprinkler pumps are created equal!
Looking to find the best sprinkler pump to keep your lawn in tip-top condition? We can help.
Why Use A Sprinkler Pump?
A sprinkler pump ensures your lawn and garden gets the right amount of water. When you combine your sprinkler pump as part of a wholly integrated irrigation system, timers and flow control completely take the guesswork out of watering.
And we shouldn't need to mention the time you can save by using a sprinkler pump. Pulling out a hose and watering your garden is incredibly time-consuming, especially if you've got a hundred other things on your plate.
Why deal with that hassle when a sprinkler pump can do it all for you?
Knowing where to start can be a little tricky, so we've pulled together a quick buyer's guide to help get you started.
Sprinkler & Irrigation Pump Buying Guide
This first step requires a bit of quick math, but bear with us.
To work our the size of the pump you need, you'll first need to work out how many sprinkler heads you're dealing with.
Next, check how much water they deliver, usually measured in GPH or GPM (gallons per hour/minute), as well as their relative PSI (pounds-per-square-inch).
To work out the required pump size, multiply your GPH/GPM by the number of sprinkler heads. For example, if you have 10 heads each at 5GPH, your sprinkler pump should deliver 50GPH. As the PSI remains constant and should be the same for all your sprinkler heads, your pump should simply match that requirement.
You shouldn't select a pump based on its horsepower (hp). Instead, refer back to the calculation performed earlier to determine the amount of water required, and the required pressure at the sprinkler heads to identify the best pump for your needs.
Avoid buying a sprinkler pump that pushes out more water or delivers a higher PSI than your sprinkler heads can handle, or you risk blowing them out. Likewise, under-sizing the sprinkler pump can cause delivery issues.
Sprinkler pumps are exposed to the elements 365 days a year. That means they need to stand up to everything mother nature throws at them, including high summer and freezing winter temperatures.
Generally, most pumps are built for constant exposure. Still, you should think twice before purchasing cheaper pumps, which may compromise on the quality of materials. Most manufacturers recommend you install an inexpensive pump cover to increase the longevity of your device.
Pump Operation & Power Supply
Some sprinkler systems are automatic – set it and go.
Depending on time or based on actual moisture conditions, your pump will tend to your lawn without you having to give it a second thought.
Most sprinkler pumps are rated for both 230v and 115v, so depending on your power supply can be tailored to meet your situation.
For those that prefer to have greater control over watering, a manual pump system can also be installed. Avid gardeners may prefer this option if they don't want to leave their pride and joy in the hands of a computer algorithm.
Pressure is measured by the number of pounds per square inch, often abbreviated to PSI. This simply refers to the force of the water exiting the sprinkler pump and sprinkler heads.
It's a key factor in determining how much area each sprinkler can cover. The higher the pressure, the further distance your water will be expelled from the sprinkler head.
Water Flow Rate
Expressed in gallons per minute/hour (GPM/GPH), the water flow rate refers to the physical amount of water that passes through the sprinkler heads during each minute/hour of operation.
Variable Speed & Self Priming Unit
Although we advise that all of the sprinkler heads in your system should have a similar PSI and GPM rating, in reality, and especially in more extensive and diverse systems, it may not be possible.
For example, a plant bed using drip irrigation will need a low pressure and flow, while a vast expanse of lawn will need the opposite. Variable speed pumps allow you to "zone" the water flow and pressure to match the needs of each of the areas you will be watering.
Before using your sprinkler pump, you'll need to ensure it is primed for use. Understanding what happens during the priming process is a little technical.
Installation Requirements & Replacement Parts
As you can imagine, installing an irrigation system, including the sprinkler pump, heads, pipes, and electronics, isn't the most straightforward job. However, should you decide to take on the job yourself, it isn't entirely beyond the abilities of those with some basic DIY knowledge.
Besides, you can find almost anything on YouTube these days. We've outlined the basics below. Before you start, check out our article outlining the 7 tools every plumber needs, which will make installation that much easier.
When purchasing a high-quality sprinkler pump, repairs will hopefully be uncommon. Still, nothing lasts forever, so it's important to have the added peace of mind that replacement parts will be readily available.
All of the pumps reviewed on our list are from reputable manufacturers, and replacement parts are readily available online, should they be required.
Price & Warranty
Most sprinkler pumps come with a 1-year limited warranty as a minimum, with some brands offering up to 3. Generally, you should expect to pay a little more for units with extended warranties.
Prices for most sprinkler pumps for home and garden use will come in at around $350 - $400, depending on the features and specifications.

2. Wayne PLS100
Best Lawn Sprinkler Pump
Max Flow Rate
14 GPM (850 GPH)
1 Year Limited
If you have a smaller backyard or lawn and are just looking for something to help with regular maintenance, the Wayne PLS100 is the best lawn sprinkler pump.
Constructed with the homeowner in mind, this ultra-compact device is super easy to use, and its portability means you can position it wherever you need it most. The PLS100 comes with a garden hose adaptor, making it easy to install and remove as required to your existing water supply.
The Wayne PLS100 is specifically designed to draw water from nearby ponds and rivers to irrigate your garden efficiently. It works effectively up to rises of 25 feet, which is enough to cover most home-use situations.
When using waters from nearby natural sources, it's essential to use a debris filter (which is not included). The pump can pull all kinds of river waste through the internal mechanisms, which could lead to permanent damage.
Another downside is that the PLS100 is not built to stay outside permanently, so you'll want to ensure you pack this away after use to keep it functioning correctly. Even then, when operating the pump, it's best to do so under some form of shelter to prevent any exposure to rain while in use.
The pump itself is fan cooled to prevent over-heating and has a handy on/off switch for ease of operation. If you're looking for something to simply maintain a small lawn, the PLS100 is a perfect choice. However, the low GPM means its unsuitable for larger areas.

This 1.5 HP sprinkler pump is one of the best selling centrifugal pumps on the market today and is highly rated for both durability and performance efficiency.
With all these added benefits, naturally, the GT15 is a little pricier than some of the other models on our list.
Types of Irrigation Pumps
A pump that uses a rotary motion with an impeller to create flow. These are the most popular type of irrigation pumps on the market, and widely available for purchase.
Using a piston, similar to a combustion engine, a displacement pump moves water mechanically through the system, with the help of valves and seals.
Somewhat intuitively, submersible pumps are designed to be submersed in water. Typically used in wells, the real difference is that these pumps draw from the surrounding water instead of a feeder pipe.
A type of centrifugal pump, these use a spinning turbine to drive water through a bell-shaped value. Turbine pumps are more commonly used in power-generating applications.
These pumps are used to increase the pressure and volume of water. They are most commonly used to increase water pressure in the home but can also be used to improve pressure in an irrigation system that covers large areas.
Installing & Replacing A Sprinkler Pump
If you've recently purchased a new sprinkler pump, you're probably wondering if you can install it yourself or whether you'll need to call in an expert.
If you have an existing irrigation setup, it's a much easier job to replace an existing pump than installing a new one, since the location is already set and both the power and water source are already available.
Improper installation is the most common cause of pump failure, so carefully follow the manufacturer's directions during the installation process. Ensure to test your seals to check for leaks, which could lead to corrosion and pump failure.
With a little bit of patience and time, most sprinkler pumps can be self-installed, and there are plenty of videos available on YouTube to guide you through the process.
Most manufacturers have repair kits available, which commonly include replacement seals and impellers.
Again, follow the manufactures directions and ensure to use only approved parts to guarantee the integrity of your sprinkler pump.
People also Ask (FAQs)
Why is my sprinkler pump delivering too much pressure?
The most likely answer is that your sprinkler pump is overpowered for your situation. Be sure to understand the gallons per minute you require before purchasing your new pump, by following the calculations we set out at the beginning of this guide.
How long should a sprinkler pump last?
With a regular maintenance routine, there is no reason why a sprinkler pump cannot last for more than a decade. Installing a cover to keep your pump protected from the elements is one way to increase its useful life.
How do you prime a sprinkler pump?
Most pumps these days are self-priming, meaning you can skip this entire process altogether. If you have purchased a pump without this feature, follow the manufacturers' instructions to work out what is best for your model.
Can a pool pump be used as a sprinkler pump?
The short answer is no. Pool pumps are designed for a specific purpose and are not suitable to be used for irrigation purposes.
What size pump do I need to lift water 20 feet?
For most lawn and garden applications, a 1hp or 1.5hp pump should get the job done. Most sprinkler pumps are designed to lift water up to a maximum of 25feet, so if you are looking for something over this, be sure to check the specifications to pick the right device for your needs.
How do I know if I have a 115 or 230-volt power source for my sprinkler pump?
Your electrician or even your local building supply can tell you the rating of the source of your power, and it's essential to get this correct to prevent damage to your pump. In the US, most power sources are 115-volts while outside of the US, such as Europe, 230-volts is more common.
Whatever the voltage, there is very little difference in terms of cost.
Do automatic sprinkler systems consume more water?
They do not. By carefully controlling the amount of water that is used and avoiding any usage when ground moisture is sufficient, automatic systems can actually work to conserve water.
Spending the time to find a sprinkler pump suited to your needs will pay off in the long run.
All of our top 6 performers were hand-selected for their superior-performance, but if we had to pick just one to recommend, it would be the Flotec FP5172. This sprinkler pump leads the way in terms of reliability and performance, making it the best all-around choice.
