Buying Guide

Choosing the best sprinkler pump out of the multiple brands and models in the market can be daunting. For you to make a good buy, you need to brace yourself with some specific information about sprinkler pumps. This section contains the crucial things to consider before buying a sprinkler pump and how one works.

How a sprinkler pump works

6 Best Sprinkler Pumps to Provide the Right Water Flow

The first thing to consider once you get a sprinkler pump is where to place it. This depends with the type of pump you have bought. If it is a centrifugal pump, you have to ensure you position it in a manner that it will not have to reach so far down to retrieve water. If it is a booster pump or submersible pump, then place it at a deeper source of water.

Once you have established a suitable position for your pump, you can go ahead to install it. You can easily do it yourself by following the manufacturer’s instructions or get professional help.

The next thing to do is determine the number of sprinkler heads that would be drawing water from the pump. Ensure your pump can operate the number of sprinklers you intend to connect it with.

After connecting the sprinkler heads with the pump, you can adjust the pressure levels and flow rates to suit your watering needs.

Remember, you cannot have the flow rate and pressure levels increased at the same time, you have to choose the one you need more.

Features to consider when choosing a sprinkler pump

There are key features you have to consider when buying a sprinkler pump for you to make the right choice. A good sprinkler doesn’t have to have all the features discussed below but a good number of them. They include:


There are various types of pumps, including; centrifugal, floating, submersible, and booster pumps. Mostly your water system determines the kind of sprinkler pump to use. Centrifugal pumps are a bit challenging to set up but are very reliable. Submersible pumps are the most efficient but can be a little challenging to maintain. Floating pumps are rare but very easy to maintain. Booster pumps help elevate the pressure of water and they can make those sprinklers you have rendered useless be compatible with your yard.

6 Best Sprinkler Pumps to Provide the Right Water Flow


Pumps have different horsepower. You should choose a pump with a horsepower that would meet your water pumping needs. For instance, if you want a sprinkler pump for watering your lawn at home, you don’t have to waste your money and energy getting a needlessly powerful one. A 1.5hp pump like the Simer 3415P reviewed above is a great choice.

Maximum pressure and flow rate

This again depends on your watering needs. Pumps have varying pressure levels and flow rates. Most heavy-duty sprinkler pumps have high pressure levels and remarkably high flow rates. They can pump up to over 700 gallons of water per hour and can operate multiple sprinkler heads.

The suction height

This is how deep the pump can draw water. If your source of water is deep, you need to get a pump that is suited to draw water from a lower point like submersible pumps. If you have a shallow source of water, you can use centrifugal or floating pumps like the WAYNE PLS100 reviewed above.

Distance to system

You have consider the distance between your source of water and your lawn, garden or the point where you want the water pumped before choosing a sprinkler pump. It would be safe to get a pump that can pull water as far as 130ft from the source of water for efficiency and convenience.

Construction materials

These determine the pump’s durability and functionality. Pumps with sturdy stainless steel or iron cast casing are bound to last longer as well as endure the harsh outdoor environment. Ensure you use pumps with stainless steel under a shade because they can heat up in the sun.

Power supply

Most sprinkler pumps use electricity, but there are those that use solar power as well. You should choose a pump that best suits that electricity plan. You don’t want to pay impossible bills in the name of watering your lawn.

A pump with a dual voltage is better as it gives you the flexibility of choosing a power supply that works for you.

Is the pump self-priming?

A self-priming pump will save you a lot of energy and time. You will not have to prime it after the first fill. The Red Lion RLSP-150 reviewed above is a self-priming pump.


The main thing you have to do to maintain your sprinkler pump is prime it. If your pump is not self-priming, then you can prime it by simply filling the space in its housing with water then switching it on to begin priming. Also, you have to regular checks to ensure the pump is not leaking as well as drain the entire sprinkler system before winter to prevent damages caused by freezing.

No. A pump should be able to pull water from the well as well as push it to the distance where it is needed.

Overheating, not controlling the pressure levels of a pump, and operating it at maximum capacity can cause it to stop functioning. Regular checks and switching off the pump when not in use can help combat these problems.

Our Verdict

A sprinkler pump is an economical way of keeping a lush green lawn or garden, and you can use it for other purposes like dewatering or transferring water from one point to another. The only problem is they are many and picking the right one can be one hell of a challenge. This guide has all the necessary information you need to choose the best sprinkler pump that will satisfy your watering needs.

Of the 6 best products reviewed, we liked the Red Lion RLSP-150 the most. Its versatility, brilliant performance, and excellent features stood out. The Goulds Water Technology GT15 and the Flotec FP5172 followed in rankings with excellent value, top-rated features and superior functionality.
