Things To Consider When Choosing The Best Backpack Sprayer

First things first, there are many aspects to consider when it comes to choosing the best backpack sprayer for your garden. Just like with lawn mowers or pruning saws, it requires a good amount of research and time for selecting a good backpack sprayer.

Granted, doing so can test your patience, but in the end, it will be worth it once you get to work. Here are the things you need to do in order to get started:

#1. Type Of Pump

To begin, the pump is one of the most important parts of the backpack sprayer that you will need to particularly look at for quality purposes.

In essence, there are two different types of pumps you can choose from, each of which depends on what you want to get accomplished in your garden:


Diaphragm Pump

This specific type of pump is especially durable, able to be used with highly-abrasive chemicals and any type of herbicide that you need to clear up your garden of nasty weeds.


Piston Pump

On the other hand, the piston pump is better used for non-abrasive chemicals. It also produces a higher pressure than a diaphragm pump, so you can get the work done quicker than usual.


Mixture Of The Two

Having a hybrid of metal and plastic can be a good alternative to all-plastic or all-metal hose nozzles, for it offers the durability of metal and the lightness of the plastic versions.

#2. Spray Wand


Once you have selected the type of pump you want, it is time to choose the spray wand that you need. A general rule of thumb is to find one which is less prone to leaks is a good place to start.

Other features you ought to consider are spraying accuracy (after all, you would not want it spraying all over the place!) and compatibility with different types of nozzles, so that you can easily switch out for all sorts of applications.

#3. Easy To Be Cleaned

Just like with any other gardening machine out there, having a backpack sprayer which can be cleaned is ideal, since then you do not waste any time doing so.

That said, keeping things simple is the way to go, since no one really wants the hassle of spending hours just cleaning out an entire machine when they can instead spend their time more wisely on other activities.

To clean a backpack sprayer, it is simply a matter of rinsing the machine out with water, making sure that there is no residue left inside of it.

In addition, it is essential to know just how to get rid of the leftover herbicide in the container, since you would not want for it to cause a safety hazard if left unattended.​

Other maintenance activities you might need to consider are winterizing storage with antifreeze elements, so that the machine does not get frozen over during potentially cold winter months.

Another factor is to lubricate O-rings and seals for a safer and more efficient operation, especially if you tend to use it a lot for gardening purposes.​

#4. Durability


Of course, it is ideal for any sort of gardening tool or machine to be sturdy and durable, able to last a long time without risking it breaking down in the middle of operation.

​A good way to check for durability is through the materials that it is made out of (solid steel? Aluminum? Plastic?), as well as to make sure that all of the parts are securely locked in place, without any sort of wiggling and looseness involved.

By taking these precautionary measures, you can ensure that you, along with the garden, will be safe to be operated.

#5. Accessories

Aside from the essentials such as the type of pump or spray wand you want to use, you might also want to look into the different kinds of accessories out there for your backpack sprayer.

While not all necessary, they can certainly make the process a whole lot easier, whether it is the case with reducing time, increasing power, and overall being more efficient.

For instance, making sure that your backpack sprayer has a good energy boost, i.e. with up to twelve volts of battery, can really save you time and energy when it comes to getting your garden cleaned up in no time.

Even further, maintaining a good caliber is important as well; in other words, being able to adjust it easily, as well as keeping a consistent spray pressure, will make it all the more efficient for you for the sake of making your garden insect and weed-free.​

In essence, choosing a backpack sprayer has many advantages for your garden. Not only does it offer high power for precise and accurate sprays, but also they are durable and versatile when it comes to selecting which nozzles to use for what purpose.​
