Things to Consider Before Buying a Backpack Sprayer

Still not sure which backpack Sprayer is the best option for you, read on this Buying guide. It will help figure out the different technical features that you should take into consideration when purchasing a sprayer.

However, you should know that these factors depend majorly on what kind of particular needs. The best place to begin is by looking at the purpose and the main type of sprayer you will be using. Here are some of the factors:

1. Purpose 

The first thing you have to do when deciding to purchase a backpack sprayer is your purpose of using it and what kind of solution you will be filling your tank with, and what kind of results you are expecting to produce.

That’s why once you decide the purpose, it will be easier for you to choose the type of sprayer you need for your target.

2. Types of Backpack Sprayers

There are mainly two types of backpack sprayers:

Piston Pump Sprayer

A piston pump sprayer can be an identifier with its up and down movements. It generally generates greater pressure, almost around 90psi, and higher than a diaphragm pumps, the other type of sprayer.

With that being said, it usually sprays far distances which are perfect for tall trees and far to reach plants. This type of sprayer tends to be cheaper compared to other types. The reason why it is inexpensive is due to the fact that it cannot be used for a certain type of chemicals that might destroy the piston.

Diaphragm Pump Sprayer

A diaphragm pump, on the other hand, is a more pricey option and they function almost the same way as the previous type. They are built-in with high-quality materials that are resistant to different chemicals.

Therefore, if you are using anything corrosive substance or solution, this is exactly what you need to purchase. When it comes to generating pressure is it usually done by pumping the handle and it gives more effective and quicker pressure.

3. Durability

Surely you don’t want to spend your money on a product that won’t last you enough, whether you are regularly spraying or not. For this, it is recommended that you look for a well known and popular brand that provides high quality and long-lasting products.

Therefore, read different reviews and testimonies from a different brand and check what kind of material is the best for your needs. It will be better if you look for high-density materials such as polythene.

4. Weight

Its name entails the fact that it will be portable the whole time of usage. That’s why weight matters. You have to take into consideration how much weight you can handle and you feel competent to carry it.

Usually most of sprayers that are available online on the market weight around 13 to 15 lbs depending on the model and the brand. This might look like not much weight that can trouble you but you should also consider the factor of the solution you will add to the tank and also to the factor of spraying for at least 1 hour or more.

5. Manual or Motorized

When it comes to choosing a manual or motorized sprayer, it always goes down to your personal choice. The most common ones are the manual, which is operated by the hand pump. Once you pump the handle, the solution goes into the wand.

You can also consider the high powered pumps which are the new advanced versions of manual sprayers. They are easy to use. The manual sprayers are usually recommended if you are treating smaller infections or small stretches.

The motorized sprayers, on the other hand, are ideal for larger sized areas. You will be able to treat that area effectively gaining both time and effort. The best thing about these sprayers is that you don’t need to continually pump the handle. However, they are usually heavier than the manual ones.

6. Nozzles

Another important factor to consider is the nozzle. Choosing the correct nozzle is crucial in defining how much liquid you will be spraying on your targeted area as well as the amount of coverage that will be handled. Generally, nozzles are coded by color depending on your situation.  The most popular nozzle varieties are Flat fan nozzles and Cone nozzles.

Frequently asked questions (FAQs)

Do not worry, this buying guide provides you with the most frequently asked questions about backpack sprayers to help you further in your purchase decision.

What is a backpack sprayer?

Backpack sprayer is a widely used gadget among gardeners specifically to spray plants, small areas, or tall trees. Depending on your target operation, you can find the type of sprayer which does the job for you. Mainly the sprayer helps individual to distribute certain liquid substances in a specific or larger areas while carried on the user’s back.

How far can a backpack sprayer spray?

You cannot have one simple answer when it comes to the spraying distance since it mainly depends on the product you are using. A manual spray differs from a battery powered spray. Generally speaking, a manual spray can spray up to 10 to 20 feet distance. On the other hand, a battery based spray can have up to 30-35 feet travel distance. Yet, for both sprayer types, wind can play a major difference in boosting the spray distance.

How many gallons does it take to spray 1 acre?

It varies from a backpack capacity to another. Yet, generally, a backpack spray tank has approximately a 4 gallons capacity of liquid. Taking the 4 gallons as a measure, a backpack sprayer covers around 5805 feet, meaning 0.133 of acre. Following this equation, a 1 acre space (43560 feet) needs around 30 gallons to be sprayed.

Can I spray water sealant through my sprayer?

There is no yes or no answer for this question since it largely depends on the type and material of the sprayer you have. As a water sealant is relatively thicker than other liquid substances, it is advised to use it only with a plastic prayer coming with brass wands to ensure a safe and effective operation.

How big of a sprayer do I need?

When it comes to spraying sizes, it really depends on your needs, bearing in mind that bigger sprayer means heavier. So it is important as well to consider how much weight are you capable on your back and shoulders. Generally, for both home based and professional operations, the average size to go for is a 4 gallon sprayer. It can meet different operational needs and it is neither too heavy for the back or it is small for larger area spraying.

Do I need a different sprayer for Roundup?

No, you can simply deep clean your sprayer and use again for another solution. However, it remains quite crucial to maintain stainless and fresh.

How many square feet does a 4-gallon backpack sprayer cover?

A 4-gallon backpack sprayer covers 5805 square feet.

How to put the straps on a backpack sprayer?

Most backpack sprayers already have the top portion of the straps pre-installed, so you can easily clamp the other end of the strap to the hook at the bottom of your backpack sprayer. In some cases, you may have to loop the bottom strap under the hook and secure it with a piece of plastic as anchoring leverage. 

What is the ideal range of PSI value for a backpack sprayer?

On average, the ideal range when it comes to the pressure for a backpack sprayer is between 20 to 60 PSI to achieve a uniform spraying pattern with the utmost accuracy. However, this doesn’t mean that anything beyond this range isn’t ideal – it really depends on what your sprayer can handle. 

What is spray-pattern and spray quality?

Spray pattern refers to the shape that the fluid takes as it is released from its source under notable pressures, while spray quality refers to the standard that classifies droplets according to their sizes. The former deals with patterns that help prevent corrosion, while the latter helps determine spray coverage. 

Is a motorized pump worth the extra money?

Yes, investing in a motorized pump will be well worth the money. Bear in mind that backpack sprayers require a good power source to push the fluid out of the nozzle. While hand-powered pumps are cheaper, they’re not usually as powerful as motorized ones, and can be quite tiresome in the long run. 

Why do spray bottles stop spraying?

There are various reasons why spray bottles stop working. It may either be because of something blocking the nozzle, or that the inner hose or tube isn’t touching the fluid. In some instances, the spray bottle may have a damaged piston seal

Piston Vs Diaphragm Backpack Sprayers: What’s the difference? Which one to Pick?

When you are out looking for anything, you come across many types of it, don’t you? Similarly, when you are out looking to buy the best backpack sprayer for yourself, you will find yourself choosing between a piston and a diaphragm sprayer. The question is what are they? how do they differ? Which is better and which one should you choose?

Let’s find out the answer to all these questions.

Piston Backpack Sprayers

As you can imagine the piston sprayers use a piston to create pressure. Apparently, this kind is capable of creating a lot of pressure, more than the diaphragm ones. This type of sprayer comes with a cylinder within which the piston resides and the piston moves up and down to create pressure.

As a result, there is contact between the cylinder wall and the piston which makes it a bit less durable. However, it is capable of producing around 90 PSI of pressure which is quite incredible. Furthermore, it has parts that are easy to access.

It may not be durable but it is easy to repair or modify. Above all that, it is very affordable. You just have to make sure you do not put in any harsh chemical wettable powders, abrasive or bleach solutions.

Diaphragm Backpack Sprayers

These sprayers are not very different in how they function from the piston sprayers. Apparently, this one also uses pressure but it uses a diaphragm that moves up and down to create pressure rather than a piston. Furthermore, it operates in a housing held together by screws.

Thus, the diaphragm does not come in contact with the wall of the container easily. As a result, this type is much more durable than the piston sprayers. This is a much-needed feature as these sprayers are not easy to fix or modify- the parts are not equally easy to reach.

Another key point that makes it different from the piston sprayers is the fact that it can create a much lower pressure- 60 PSI maximum. Other than that, these sprayers are way more capable of dealing with chemicals.

It can handle the harsher, abrasive bleach chemicals that the other type cannot handle.

Which one will you choose?

Choose the Piston Sprayers when:

  • You need a high amount of pressure when you are spraying.
  • If you want to repair or modify the sprayer easily to use it in any way you want.
  • In case you need something affordable.

Choose the Diaphragm Sprayers when:

  • A lower amount of pressure won’t harm you.
  • You need to use harsher chemicals that would otherwise harm the piston sprayers.
  • You can handle a higher price.
  • In case you need something more durable.

 Best Backpack Sprayers: Picking the Right One for your Needs 

There are a number of things you have to consider when you are buying a backpack sprayer. Let’s check these things out.

The Type of Backpack Sprayer you need 

You already know that you have to choose between a piston and a diaphragm sprayer. Furthermore, you know which one is good for what. Now, you have to consider another type- manual or motor.

As you can imagine, the motor sprayers will reduce the load on you. Therefore, they are suitable when you have to deal with a large area of land. Otherwise, a manual will be fine if you are comfortable with it.

The choice depends on what you are comfortable with and the amount of work you need to do.

The Tank Size 

The tank or cylinder will come with the sprayer obviously and you have to make sure it is of the right size. Now, the right size depends on the size of the area you will be working on. The larger the cylinder, the longer you can go without needing to refill.

But, there is another consideration. Since you will have to carry the sprayer on your back, you need it to be lightweight enough for you to carry it. Therefore, you have to find the midpoint between a reasonable weight and a good capacity. You will usually find the capacity in gallons.

The Seals and Gaskets 

You will be keeping liquid and spraying it with the sprayer. Therefore, you cannot afford leaks or lose points. Thus, you will have to check the various seals and gaskets on the unit. Firstly, check that it has the right number of them. Secondly, check that they are both efficient and effective.

Furthermore, seals and gaskets vary based on the chemical you use. Therefore, make sure that the seals and gaskets are right for the type of chemical you plan to use.

The Nozzles 

These are another important consideration as they make the whole process convenient for you if chosen right. You need to spray the chemical in various ways and in various places. You need to reach those places right and be accurate as well.

And, nozzles play a huge role in these and so does the hose. Apparently, there are various nozzles available for various kinds of jobs. If you are going to spray only in one way, a nozzle best suited for your job will do.

However, if you need to be versatile, then you need interchangeable nozzles. Then, you can just spray around just the way you need to. 

The style and comfort of the backpack sprayer 

You will be carrying the backpack sprayer on your back and that is not as easy as you think it is. Because the tank has quite a lot of weight and it can get tiresome after you have sprayed for a while. Thus, you need to feel comfortable.

The main part where you can expect some comfort is the straps of the backpack. They should distribute the weight equally and should also be adjustable. Other than that, padding in the straps will keep you out of harm’s way.

Chest or back straps can come handy in this case as well. Just choose a design that supports you wherever you need it to.
