Buying Guide

backpack sprayer reviews

When you purchase a backpack sprayer, you will get a really versatile tool. An excellent model will make work in your garden an easy task. Except for gardening, you can use this unit for cleaning the exterior of your house, a car, and a boat. Also, it is practical for applying fertilizer in confined spaces.

There is no product which is the right choice for everybody. That is a reason for picking out an adequate backpack sprayer just for your needs. I will list here the primary components of an ideal backpack sprayer, so you can find which one fits you best.

No matter which one model you choose, it will have a tank, nozzle, wand, pump, and shoulder straps or harness. Let's see.

Tank

Thanks to this part, most models available these days are quite lightweight. It is made of durable polyethylene plastic, which is resistant to UV radiation and chemicals.

A spray tank capacity is usually between 2 to 4 gallons (7.6 - 15 l) of liquid, which is enough for any average residential purpose. Keep in mind that its weight will increase with a higher capacity.

Nozzle

Since this part controls the flow and pattern of the spray, you can consider it as the most important part of your device.

Types of the nozzle can be different, which will allow you to get various types of spray patterns. The most common are nozzles with a direct stream, a narrow or wide stream, a fan or cone type, as well as adjustable ones.

That diversity is practical because you can use your unit for spraying either a small area or a larger one as well. The best option is to choose a backpack sprayer with adjusted nozzles with wide options of the spray pattern.

Also, take care to pick out the nozzle made out of the right material. The backpack sprayer with a plastic one will be less expensive, but you will need to replace it after a while since nozzle will degrade over time. Those made from brass or bronze are expensive, but you will save some money in the long term since they last longer.

Wand

This piece allows you to channel and spray the liquid onto the desired target. If there are hardly accessible places in your garden that you need to reach and spray, you need to choose the unit with a longer wand.

Pump

This part of your unit is essential since it draws the liquid from the tank. After it sends it to the chamber, it will be held there under pressure by seals and valves until you squeeze the valve on the wand.

Shoulder straps or harness

Since your backpack sprayer is designed to be portable, you will need to carry it around. Therefore, comfortable straps or a harness can make a difference during the work.

The crucial thing is that straps fit over your shoulders and across your chest ideally. That will help distribute the weight of your unit and let your hands entirely free to perform every task you need to finish.

Conclusion

My top choice is definitely Chapin 63985 four-gallon backpack sprayer. If you pick out this particular model, you will get a sprayer with a top-quality Black & Decker 20-volt lithium-ion battery that will allow you regular work for 1 hour and 45 minutes.

Its tank has an extra-wide opening of 6 inches (15 cm) which will help you to finish all maintenance comfortably and quickly. Plus, there will be no spilling the chemicals while pouring it into the tank.

One of the rare disadvantages of this model is a high price, but it is worth every cent invested. Also, if you avoid overfilling the tank, there will be no leaking the liquid through the lid as well.
