Pick A Best Backpack Sprayer with It’s Features 

Now comes the crucial part where you decide which best backpack sprayer will fit your requirements. Read on and find out what are the main factors to consider before you decide on the right choice.

  • Commercial or domestic use

How long are you going to use the sprayer in a day? If you are a commercial landscaper, then you might be pumping by the gallons per day. Then the best fit for you is a sprayer with a motorized pump. A sprayer with a manual pump might not be a good choice for commercial usage. The pressure generated by an electric pump is even and higher than the pressure generated by a manual pump. Moreover, manual pumping is too tiresome. If you are a domestic user and don’t mind the good arm workout, go for a sprayer with a manual pump. Motorized pump sprayers weigh more, cost more, and are noisier than sprayers with manual pumps. Larger areas are better covered with the former, while smaller areas might require only manual pump sprayers.

  • Piston pump or Diaphragm pump:

Sprayers with piston pumps are less expensive, but the wear and tear associated with a piston pump are high, and the parts need to be replaced often. Diaphragm pumps, on the other hand, are much more expensive, but long-lasting too. Diaphragm pumps work with all kinds of pesticides and liquids.

  • Nozzles:

Every sprayer comes with many kinds of nozzles: A gush of liquid, a mist, or wide swathes – you can get them all with one sprayer. Most sprayers come with changeable tips. Some manufacturers save you the trouble of hunting for different nozzles by giving a single adjustable nozzle. Plastic tips are the most common, but if you are looking at longevity, go for brass or nickel tips.

  • Ease of Use:

Is the sprayer easy to use? How easy is it to fill up the tank, or how effectively can you clean the tank up? Most tanks come with a wide opening for easy filling. All sprayers come with a basic two stage filtration set up, but some manufacturers go a step ahead and give three stage filtration also. Filtration makes the cleaning process easier and spraying more effective.

  • Durability and Sturdiness:

Look out for the durability of the shoulder straps, sturdiness of the plastic tank, long lasting nature of the various seals, gaskets and fixtures of the sprayer. Take into account the sturdiness of the hose and the wand also. Viton seals and gaskets don’t deteriorate on contact with chemicals. Plastic is corrosion resistant but doesn’t last as long as metal fixtures.

  • Value for money:

This factor is pretty important. Sprayers with manual pumps are less expensive than the ones with motorized pumps. Look for pumps that give back their value in money. Good quality costs more, and longevity improves the value for the money you pay.

  • Comfort:

You are going to wear the heavy sprayer for a pretty long time. Look for sprayers with padded shoulder straps and chest straps too. Most of the sprayers mentioned in this guide have issues with the straps, except for the one by Field King. The other sprayers just fall a little behind, but there is nothing like a separately bought shoulder harness to make things a bit more comfortable.

  • Safety:

Safety is another main factor to keep in mind. You don’t want chemicals leaking out, nor explosions due to unregulated pressure. Go for leak proof designs, sprayers with regulators for pressure, and safety valves. Leak-proof sprayers make sure harmful chemicals don’t leak out of the sprayer and endanger your health. Regulated pressure also makes sure there are no dangerous line explosions.


Backpack sprayers are good, practical additions to any household with a big garden to maintain. Commercial landscapers and agriculturists also benefit a lot from choosing the right sprayer. Before we conclude, let us give you a bit more information on how to get the most of any type of backpack sprayer.

Staining of wooden fences, wooden decks, and treating mildew is also made easy with a backpack sprayer. Cleaning up hard to reach areas like garage roofs, pressure cleaning of pathways are all easy as pie with a sprayer.
