Buyer’s Guide: Things You Need to Know About the Best Backpack Sprayers

Buying a backpack sprayer may seem easy, but it isn’t! You have to consider a plethora of parameters that can influence the performance of the sprayer. Here in this buying guide, I’ve highlighted the essential factors you should check to make the most out of your purchase.

Motorized or Manual

Generally, there are these two types of backpack sprayers available in the market, and you have to choose one based on your requirements. Motorized sprayers are powered with batteries, so you don’t have to invest any manual efforts in pumping the pressure.

On the other hand, manual backpack sprayers require you to pump pressure inside the tank so that you can spray the chemical on the field. A motorized backpack sprayer is an ideal choice if you have a massive field to spray, whereas manual sprayers work well for small lawns and gardens.

Pump Type

You can choose a backpack sprayer based on the type of pump it has! There are two types of pumps available, i.e., diaphragm and piston pump. Diaphragm pump sprayer works well even with dry herbicide formulation, and you will get better longevity with them as compared to piston pump sprayers.

On the other hand, backpack sprayers with piston pumps are relatively cheaper and easy to maintain.

Still, getting confused about which pump type to buy?

Check this video out to find out the significant differences between these pump types.

Capacity of Tank

Another essential aspect is the capacity of the tank. If you have to spray a bigger area, then a sprayer with better tank capacity will be great. As a result, you don’t have to refill the tank multiple times, and you can spray the field in one go. Sprayers with lesser tank capacity are a good option in case you have a small area to cover.

Durability

A backpack sprayer has to withstand the harsh UV rays emitted by the sun along with the climatic conditions. Also, it should resist reacting with the chemical you will carry in it. Make sure to buy a sprayer that is durable enough to pass the test of time. All the backpack sprayers listed here are durable, and you can expect a decent lifespan with them.

Interchangeable Nozzles

A backpack sprayer with interchangeable nozzles is perfect for multiple spraying tasks. Not every type of plantation requires the same nozzle, and you will get added benefit by purchasing a backpack sprayer with interchangeable nozzles.

Note: Check whether the manufacturer offers the nozzles with the sprayer, or you have to buy them separately to avoid spending more money.

Changing the nozzles frequently may require you to calibrate them for better spraying. Check this article to know more about calibrating the nozzle of a backpack sprayer.

Comfortable Straps

Carrying a backpack sprayer isn’t easy, as you have to carry the weight of the chemical plus the weight of the sprayer. Comfortable straps will make it convenient for you to carry the sprayer for a prolonged time. Nowadays, most manufacturers offer quality straps with the sprayers, but it would be great to check it before making the purchase decision.

Lockable Trigger

A lockable trigger is an essential component of every backpack sprayer. There are two benefits associated with a lockable trigger one if you don’t have to press it with your hand continuously, and the second one is it prevents the chemical from dripping when you are not spraying.

Also, a lockable trigger eliminates hand fatigue, and you will get a pleasant experience with backpack sprayers equipped with it.

Safety

The tank of a backpack sprayer has to bear a lot of pressure in order to spray the chemical, so safety is indispensable. Generally, most of the backpack sprayers available in the market guarantee ultimate safety provided that you are buying a branded one.

Easy to Refill

Refilling is a task you have to do multiple times, so go with a backpack sprayer that has a broader tank opening. Refilling a tank with a small opening can be challenging, and it can result in wastage of chemicals.

Budget

Usually, backpack sprayers don’t cost an arm and a leg; still, you should consider your budget before buying one. These devices are available at a plethora of prices, so you will get a reliable option even if you have a packed budget.

Tips to Make Your Backpack Sprayer Last Longer

Just like any other gardening equipment, a backpack sprayer requires regular maintenance. If you want your sprayer to last longer, then here are some tips you should know.

Never Forget to Clean the Sprayer After Use

How often do you clean the backpack sprayer? If you answered once in a week, then it can dramatically reduce the life of the sprayer. You should clean the sprayer after every use to prevent the nozzle from clogging. The table powder mixture can form a hard material, and that can clog the nozzle ultimately making it unfit for spraying.

Always clean the sprayer from top-to-bottom to ensure that it performs well and lasts longer.

Winterize It Properly

Properly winterizing the backpack sprayer protects the machine from the harsh climate. You can add the antifreeze solution to the tank of the sprayer to make sure that it sustains winters without getting damaged.

Take Care of the Seals

There are multiple types of seals attached to the sprayer that prevents it from leaking. You should check the seals after some time to make sure that these don’t need a replacement. Never use a backpack sprayer with a damaged seal as it can lead to leakage, and will curtail the performance of the sprayer. Always keep some o-seals and Viton seals handy so that you can replace the damaged one on the go.

FAQs

  • How often do I have to pump a manual sprayer?

Pumping is required to build pressure inside the tank for spraying the chemical. You have to pump frequently to maintain the pressure; else, the sprayer will not deliver its full efficiency. Buying a motorized backpack sprayer will eliminate the need for pumping, and you can use it with ease.

  • How can I spray between ornamentals and crops with my backpack sprayer?

You need a spray drift guard to spray between ornamentals and crops without damaging the flowerbeds. Get a spray drift guard like Solo 4900430 sprayer and attach it to your backpack sprayer.

  • How durable is the plastic tank?

The plastic tanks are made using high-density polyurethane, which is quite durable and resists reacting with the chemical filled inside them. So you can rest assured that the tank will last longer than you think.

  • Is a motorized backpack sprayer worth its price?

Using a backpack sprayer with a motorized pump will save your precious time and requires fewer efforts as you don’t have to pump it manually. So it is worth every single penny to invest in an excellent backpack sprayer.

However, it depends on your requirements, as well! If you are looking to spray your garden once a week, then a motorized backpack sprayer is not a worthy option for you, as you can get a manual one for a better price. Motorized sprayers work well for the users who have to spray their field every now and then or involve commercial usage.

There are some good manual as well as motorized sprayers reviewed in this article so you can make your choice accordingly.

  • Are motorized backpack sprayers noisy?

Yes, motorized backpack sprayers are a bit more noise as compared to manual sprayers. Similarly, battery-powered sprayers emit less noise than gas-powered sprayers. If you need a neatly silent backpack sprayer, then go with a manual device like Field King Professional 190328 or buy a battery-powered one.

  • How long does the battery last?

It depends on the type of backpack sprayer and the capability of the battery. A bigger battery can deliver more run time as compared to a smaller battery. For example, Chapin International 63985 comes with a medium-sized lithium-ion battery that lasts somewhere around 1.75 hours, which is enough to spray bigger fields.

Final Verdict

Having the best backpack sprayer is indispensable to safeguard your plants from pests and weeds. Choosing a sprayer from this list will reward you with the assurance that you are buying something recommended by the experts.

In my opinion, the M4 MY4SONS 4-Gallon is the top backpack sprayer as it has an excellent battery life and is ideal for bigger fields. If you have a packed budget, then go with Field King Professional 190328 as it is the best sprayer under the budget.
