Best Backpack Sprayer Buying Guide

So you’re looking through our backpack sprayers reviews, but you don’t know what to pick yet. Well, don’t worry.

We want to help you pick something that matches your needs. Whether you want to fertilize your garden, kill weeds in your lawn, or simply spray some herbicide in your crops – you’ll find the right sprayer by learning more about them.

Next, you’ll find a list of factors you need to think about before choosing a backpack sprayer. Take a look:

Pressure & Reach

To get the most out of your knapsack sprayer, you must pick something with sufficient pressure (PSI) and enough reach accordingly.

This pressure level can go anywhere from 20 PSI in a low-quality prayer up to 150 PSI in the best models. But a typical sprayer will offer between 40 and 80 PSI.

We recommend going for as much PSI as you can. Just remember that PSI makes water go out faster & harder through the nozzle, so it affects reach as well as precision.

It should reach no less than 10 feet from the place you’re spraying from. And it should have enough precision, so you don’t waste any of the chemicals.

For the best results, be sure to get an adjustable pressure system – so you can set the backpack sprayer depending on your specific needs.

Wands & Nozzles

Not only you want to enjoy pressurized knapsack spraying, but you also want it to be comfortable and easy. That’s why you should always go for large wands, comfy grips, and adjustable sprays.

A quality backpack sprayer will help you pick between a gentle mist, rough stream, variable volume sprays, and more.

At the same time, you want a long wand that allows even more reach – so going for something between 40 and 60 inches will be your best bet.

Lastly, consider extra accessories and compatibility. A set of nozzles and compatibility with TeeJet systems are always worth having.

Tank Capacity

The tank sprayer capacity is also critical for an excellent experience. Most back sprayers offer a 4-gallon system – which is the standard for most applications. Yet, you may find some models going up to 8 gallons for extra capacity, and some going as low as 1-gallon, which allow easy use.

Here, make sure to pick something that matches your garden, lawn, or crop size. The most accurate capacity that fits your demands, the fewer times you’ll have to refill it.

Ease of Use

From the tank to the wand, everything should be a piece of cake to operate in the best backpack sprayer.

For the tank, for example, you want a wide-enough mouth opening so you can pour chemicals and water inside with ease. It should open and close easily, so a grip-oriented valve/lid is always worth considering. For that, it should be no less than 3 inches and no more than 6 inches in diameter.

Similarly, you want the wand to be light and easy to handle. It should boast a grip-oriented shut-off valve that makes spraying effortless. A pump handle also allows easy pumping when needed. And with a built-in agitator you can mix the liquids inside the tank with ease.

On top of that, changing the spray pattern shouldn’t take more than just a few seconds. And if it has accessories, then they should offer a straightforward setup.

Comfort & Portability

Once you’ve figured out the ease of use, then you can jump to comfort and portability. Here, you’ll have to think about padding, strap quality, adjustability, and support.

For example, a padded shoulder strap system is always worth considering. It will make carrying the backpack tank a lot easier. And if it is adjustable, then you can make it fit your body as needed.

The padding quality also matters. Some padded straps are way more comfortable than other padded straps, so go for thickness for the best results.

And sure enough, you also need to consider any extra support. Some backpacks come with lumbar support to prevent strain while offering a chest strap so you can decrease pressure points.

As for portability, any handle, storage, wheel, or similar feature will come like a charm. Anything that makes carrying the sprayer a lot easier is always worth considering.

Safety & Filtration

A plant sprayer also needs to be safe, leak-proof, and excellent at filtrating stuff.

For this, you’ll have to consider a leak-proof design with well-made tank valves and Viton seals. Likewise, you should think about a translucent tank. If it allows you to see inside and check the liquid/product level, then it’s a lot safer to use.

But the ultimate safety feature is always an effective filtration system. Here, you’ll find that they come in stages. Some filters offer only one stage (a basket/colander), while others provide built-in filters and removable cartridges for extra effectiveness.

The safer the backpack sprayer is, the better your experience will be.

Durability & Materials

And last but not least, the best backpack sprayer is always long-lasting.

A durable model will always be more pleasant to use than a non-durable one. And for that, nothing matters more than a quality array of materials. With the right materials, the product can stand constant use of chemicals, resist continuous use under the sun, and still work at different temperatures.

Polyethylene tanks, UV-protected plastic, threaded wands, PVC hoses, high-density materials, and others – they’re all excellent things to go for. Anything that adds up to the sturdiness and durability of the backpack sprayer is always worth considering.

FAQs (Frequently Asked Questions)

You already went through our best backpack sprayer reviews and learned about some of the most important factors, let’s now explain some of the lesser-known aspects about them.

The following questions will give you a more in-depth look into what backpack sprayers offer and how you can get the most out of them:

What to use to clean out a backpack sprayer?

To clean a sprayer tank, you only need soap, detergent, or any similar product, and water. You just need to empty the tank from any chemicals. Then fill it with water and soap and agitate. If the sprayer comes with a built-in agitator, then it will be easy. Finish by getting rid of the soapy water.

What is the difference between a piston and diaphragm sprayer?

A piston pump refers to the part that pumps the water out automatically. This pump design is usually battery powered. In contrast, a diaphragm pump refers to the manual pump sprayer that creates pressure from pumping using a pump handle. This pump design is less practical yet more reliable.
