Sprinkler systems are a great way to keep the lawn green and flowers healthy, but when a pond, lake, or well is the primary source for water it can be difficult to achieve the proper pressure and water flow. Sprinkler pumps provide constant pressure through the system, making it possible to better regulate the flow of water. They can also be used in very shallow ponds and wells so available water doesn’t go to waste.

Choosing the best sprinkler pump for your home can seem complicated if you aren’t sure what you need. Take a look at the top products below and think about the sprinkler pump type, pressure level, flow rate, and suction head that’s best for your property. Another important factor in determining the best sprinkler pump for your situation is the distance from the pump to the sprinkler system, so it might make sense to take some measurements before shopping.

What to Consider When Choosing the Best Sprinkler Pump

Sprinkler pumps are a good choice for water irrigation systems that are fed by ponds, lakes, or wells, but finding a sprinkler pump for your yard needs should start with an understanding of how these pumps operate. Some of the important criteria to think about include pump type, material, horsepower, power supply, and a few other important considerations mentioned below.

Type

The type of sprinkler pump that’s best for your needs is primarily based on where the pump needs to be in relation to the water source in order to operate. Most pumps you encounter will be centrifugal, submersible, or booster sprinkler pumps.

  • Submersible sprinkler pumps are simple and effective when they’re used in a deep source of water. As implied by the name, these pumps must have their inlet fully submerged to function properly. For this reason, they aren’t a good option for shallow streams or wells.
  • Centrifugal sprinkler pumps are a great option for shallow sources of water because they use a hose to draw water into the pump. For the pump to work properly, the water source has to be just deep enough to fully submerge the end of the hose. These pumps can burn out if the water source runs dry, however, because they aren’t designed to pull in air.
  • Booster sprinkler pumps are a subset of centrifugal sprinkler pumps that boost the water pressure through an existing system. A primary pump draws water from a water source, sending it through a hose to a booster sprinkler pump, which increases the water pressure as it flows through the pump, and then directs the flow of water to the sprinkler system. These sprinkler pumps can also be used as primary pumps if necessary.

Material

A sprinkler pump’s durability and resistance are strongly correlated to the material used in its construction. Common materials used for these pumps include stainless steel, fiberglass-reinforced thermoplastic, and cast iron.

  • Stainless steel is a water-resistant material commonly used for sprinkler pumps because it’s durable enough to protect the pump from impact damage. It’s also lightweight, ensuring that the pump isn’t too heavy to carry or set up.
  • Fiberglass-reinforced thermoplastic is completely waterproof and usually lighter than either stainless steel or cast iron. However, it isn’t as durable as either of the others, so it may not be a good choice for rough work environments.
  • Cast iron is made for strength and durability, but it’s heavier than both stainless steel and fiberglass-reinforced thermoplastic. This can be a good thing for submersible sprinkler pumps because the extra weight allows cast-iron pumps to sink quickly and remain submerged.

Horsepower

Sprinkler pumps are driven by an internal motor, which allows them to pull in standing water and pump it out over a short distance. The more powerful the pump’s motor, the better it is at pumping water. Powerful pumps mean increased pressure output, flow rate, and suction depth. They also allow water to be pumped a greater distance from the sprinkler pump to the sprinkler system.

The power output of a motor is measured in horsepower (HP). Smaller sprinkler pumps may have motors capable of a maximum power output of just 0.16 HP, while more robust pumps may have motors that can exceed 3 HP. The most common sprinkler pumps use motors with power outputs between 1 HP and 1.5 HP.

Power Supply

When shopping for a sprinkler pump, it can be easy to focus on the water pressure, flow rate, and pump type, but it’s just as important to determine the type of power supply (and in the case of corded pumps, the length of the power cord). A short cord length might eliminate some pumps from consideration unless the user is willing to invest in a waterproof extension cord.

Most sprinkler pumps use direct electrical connections to a power outlet or power generator through an extension cord in order to operate, though there are some exceptions that may run on solar power. Some pumps will also have a dual-voltage option that allows the pump to run using either a 115V power source or a 230V power source.

Pressure Level and Flow Rate

Pressure level and flow rate are used regularly to determine which product would be the best sprinkler pump for a specific sprinkler system. Pressure is expressed in pounds per square inch (PSI), and the maximum pressure output of the sprinkler pump should meet or slightly exceed the maximum pressure output of the sprinkler heads. If the pressure output is too high it could damage the sprinkler system.

Flow rate is generally measured in gallons per minute (GPM), though some manufacturers label their pumps in gallons per hour (GPH) to make the flow rate look more impressive. This flow rate can range from just 10 GPM to over 100 GPM for the standard sprinkler pump, while pressure output typically starts at about 40 PSI and can exceed 150 PSI for commercial applications.

Suction Head

The suction head, or suction depth, is measured in feet (ft) and refers to the maximum depth at which the sprinkler pump can draw water. The deeper a pump’s inlet hose is placed, the more difficult it is for a centrifugal pump to pull water up the length of the hose and through the pump. Submersible sprinkler pumps are also limited by the suction head; they are trying to push water up a hose instead of pulling it, which reduces the maximum distance the pump can be from the sprinkler system.

Keep in mind: Depth doesn’t just refer to water. If the pump hose needs to be dropped through 10 feet of open air before reaching the water source it will also need to pull water up that same 10 feet, creating an increased strain on the pump. Look for a pump that has an appropriate suction head for the depth of the water source.

Distance to System

The distance to the sprinkler system from the pump matters. This is one way of determining whether a sprinkler pump is appropriate for a sprinkler system or if it isn’t powerful enough to transport the pressurized water the entire distance between the water source and the sprinkler. If the distance to the system is too short, the pump will not be able to maintain the pressure and flow rate of the water all the way to the sprinklers.

The distance from the sprinkler pump to the sprinkler system can range from under 10 feet for some submersible sprinkler pumps to well over 150 feet. Before choosing a pump, it’s a good idea to measure the distance from the water source to the sprinkler system inlet, as you want to be sure that the pump will be effective at transporting water to the sprinkler heads.

How We Chose the Best Sprinkler Pumps

Finding the best sprinkler pumps was possible after conducting research into all the important features needed in draining and pumping water effectively. The key factors that should be included in sprinkler pumps should always be water pressure (GPM/GPH or PSI) and the water depth at which a pump can function properly.

Many of the above picks also have features that enhance user-friendliness like durable casings for long-lasting use, handles for pump removal and placement, screens to prevent large objects from entering the pump’s mechanisms, and even dewatering outlets to remove water from the pumps after use.

Many of the pumps available also have long power cords for easy plug-in and installation. However, it is always important to check the depth at which a pump can be placed and ensure that the water pressure meets the needs of your project.

FAQs

Before investing in a new sprinkler pump for the sprinkler system, take a look at these frequently asked questions and their answers to learn more about which pump is most appropriate for keeping your lawn and garden green and healthy.

Q: What size pump do I need for my sprinkler system?

Determine the proper size for the pump based on the sprinkler head pressure requirements that are measured in gallons per minute (GPM) and pounds per square inch (PSI). Multiply the GPM measurement by the number of sprinkler heads to find the GPM requirement for the entire system, then compare the GPM and the PSI, and look for a pump that can handle this pressure requirement.

For instance, 10 sprinkler heads that are rated at 40 PSI and 6 GPM will equal a system-wide requirement of 60 GPM at 40 PSI. Choose a pump size as close to this output as possible; a pump that is too powerful could blow out the sprinkler heads.

Q: Does a sprinkler pump need a pressure tank?

A sprinkler pump can work without a pressure tank, but the pump will wear out at a faster rate because it must cycle on and off repeatedly.

Q: How do I maintain a sprinkler pump?

There are three important things to do to maintain a sprinkler pump. The first is simply priming the pump with water before turning it on to ensure that the motor doesn’t burn out. The second is conducting regular inspection checks to determine if the pump is leaking. The final step is to winterize the pump by draining the entire sprinkler system before freezing weather hits. This prevents water from freezing and cracking the pump, hoses, sprinklers, valves, and any fasteners throughout the system.

Q: How long do sprinkler pumps last?

Sprinkler pumps generally last between two and five years, though they will last longer when they are properly maintained.
