It sprays stream uniformly with a variety of different nozzles to reach the spray all over the area, even hard to reach areas. They are available in different sizes and features to accommodate different requirements.

Before investing in this backpack sprayer, we recommend you consider these factors which assist you in choosing the best sprayer.

  • Capacity –Usually, we fill pesticides, fertilizers, insecticides, or other liquids to spray on the garden or home. So, it is essential to check the capacity of the sprayer before buying. The tank capacity is expressed in gallons, and a sprayer with a larger capacity is perfect for a large lawn. Most of the below-mentioned sprayers are 4-gallons, which is enough for an average-sized lawn (5000 – 10,000 sq. ft.). 
  • Manual or Motorized –The sprayer uses an internal pump to draw out the liquid, and this pump is operated either manually or motorized.
  • A manual sprayer uses a hand pump to pressurize the liquid and force it up for effective spraying. It is lighter, affordable ($40 – $150) that suits small-sized properties or small infestations, yet leaves you with hand fatigue.
  • A motorized sprayer is powered by either gas or battery, in which battery-operated model is versatile and easy to setup. It pumps up the liquid automatically to the wand. It is heavier, expensive ($100 – $500) and suits large projects and busy professionals.
  • Nozzles –We use Backpack sprayers to spray chemicals uniformly, which is done through a proper nozzle (controls the flow rate). So, the sprayer nozzle type and the number of nozzles is crucial to check. Also, they offer different fan volumes and spray patterns, in which most are adjustable to spray in the desired manner.
  • Weight –Since we need to carry a backpack sprayer to spray all over the lawn. Therefore, it is a must to check the weight and insists on picking a lightweight backpack sprayer. All the below mentioned sprayers weighs within the range of 7 – 15 pounds, which allow you to carry them easily on your back without much strain.

How to Choose the Right Backpack Sprayer:

A backpack sprayer is a versatile garden tool also known as tool backpack for garden and to get the most benefits out of it upon regular use to maintain a healthy garden. Here are some of the must to consider features while shopping for the backpack sprayer.

1. Manual Vs. Motorized:

Usually, this backpack sprayer uses an internal pump to draw liquid out of the chamber through a hose, and then out through a nozzle and wand. This internal pump is operated by either a motorized system or manually. Let’s know about them in detail to know which type suits you best.

  • Manual Backpack Sprayers –

This type of sprayer is operated with a hand pump that is attached to the backpack chamber. When you pump the handle, the pressurized liquid is forced up into the wand ready for spraying. They are quite affordable, yet causes hand fatigue if using it for a long period. These days, most manufacturers designed their sprayers with high-powered pumps to use them with ease without much strain on their hands.

A good quality manual sprayer works effectively while treating smaller infestations (or) on a smaller sized property. Some sprayers offer adjustable handles that allow you to change from right to left-handed to make it easy for you to work comfortably. The price range of these sprayers will be $40 – $150.

  • Motorized Backpack Sprayers –

This type of sprayer is powered by either gas or battery, in which battery-powered models offer more versatility and are easy & simple to set up. A motorized sprayer will pump the liquid automatically from the backpack chamber to the wand without any physical effort.

It is used widely for large projects and long workdays, which runs within the price range of $100 – $500. These are expensive, heavier, and need extra maintenance that makes them the best choice for professionals who use them daily.

Verdict –

A manual backpack sprayer is the best option for smaller yards (or) average homeowner (or) people using once per season jobs, yet it is less expensive than motorized ones. While motorized sprayer is the best option for busy professionals who uses the sprayer daily to spray for longer hours at once.

2. Pressure (PSI):

The pressure of the backpack sprayers varies greatly, and it should match the intended application. The amount of pressure in this sprayer is measured in PSI (Pounds per square inch), which makes it able to propel over its nozzle.

PSI is an essential feature that ensures proper working of the sprayer. An uneven spray is produced by the sprayer having much less pressure, which reduce the efficiency of their contents. However, a sprayer with much more pressure is extreme/more to deal a small yard.

The PSI range of backpack sprayers will be 40 – 150 PSI, in which the average PSI will be around 70 PSI.

For a large yard having various inaccessible spots (or) a professional working in several spaces of different sizes, then use a sprayer with 70 (or more) PSI rating. For smaller or average-sized lawns, a sprayer with 40 – 70 PSI rating is sufficient for spraying all over the space. It provides a horizontal spray of around 15 – 20 feet. Thus, it allows better coverage, without causing the operator to move everywhere for spraying.

Most sprayers combine some type of regulator into their design, which let you turn a knob and reduce the pressure coming into the spray nozzle. This helps to keep the consistent flow of product/spray, which is a better feature while applying a sensitive product that requires consistent coverage.

3. Diaphragm Vs. Piston:

In general, diaphragm pump and piston pump are two main types of liquid delivery systems available for the backpack sprayers.

  • Piston Pump –

It draws the content from the tank on the upstroke to an enclosed chamber and then pushes out the liquid from the nozzle or outlet valve on the downstroke. This pump type produces pressure of up to 150 PSI, which makes it a great option for higher pressure applications.

Yet, it is not suited to use extremely abrasive chemicals, as these chemicals might destroy the piston. Also, this pump won’t accept a wettable powder spray. With its simple design, valuable PSI ratings, and effortless accessibility for its repairs, these piston pump sprayers are quite popular for householders (or) those having small lawns or garden areas.

  • Diaphragm Pump –

Though this pump works similarly to piston pumps without any internal cylinder, but a bit costlier option. Here the handle pumping moves the diaphragm & thereby create the required pressure to draw out the liquid/spray. It provides a pressure range within 40 – 60 PSI, yet can easily accept a much greater range of products (both liquids & powders) compared to a piston pump.

It is designed to use by professionals using potent weed killer chemicals and pest control. This sealed system moves the liquid from one chamber side to another by using a diaphragm, which means one side is full and the other side is empty. This pump is made of chemical-resistant materials and thereby produce more PSI than piston pump, which makes it the best choice for pros.


A diaphragm unit is the best option when working standard on-ground weed spraying, where high PSI is not required. If having lattice work (or) other areas requiring overhead spraying, where higher pressure PSI is needed for overhead application, then piston pump is an ideal option that moves more quickly, yet not to be used with all chemicals.

4. Sprayer Tank Capacity:

The liquid holding capacity of a sprayer tank is essential to consider while making its purchase. If it won’t hold enough quantity, then you have to stop most often while doing large jobs. While too heavy tank will make you not to be comfortable to use.

The range of tank capacity for sprayers is available within 2 – 7 gallons, in which the sprayers that come within these two size extremes are considered true backpack sprayers (lightweight to hold and carry on back). However, the smaller capacity sprayer (than the above range) is toted with a handle, while the larger capacity tank is carried with a wheeled cart.

For typical jobs like spraying an insect infestation or fertilizing a lawn (from 5000 – 10,000 square feet), a sprayer with a 4-gallon tank works well.

5. Spray Wand:

A good quality spray wand is crucial for accurate application of chemicals you need to spray on the shrubs, trees, and other things along with user comfort. However, there are many different types of wands available in the market. These spray wands are made of polyethylene, brass, or aluminum, in which each material suits different chemicals. So, check them and use the right one for your requirement. Among these materials, brass is durable and widely used material.

Also, we get wands with different grips like handgun grips that allow the user to use them with ease, especially while suffering from hand or fingers pain (or) spraying a lot. So, pick the spray wand that fits properly to prevent any leakages and offer an exact aim. Also, ensure to check for the compatibility with nozzles and caps that has with sprayer.

6. Spray Nozzles:

One can find the spray nozzles at the end of the wand that is used to control the spray patterns and flow rate. Most of these backpack sprayer models offer many different adjustable tips in varying sizes and spread. In general, there are four main spray patterns available – cone, fan, direct, and wide stream. You have to buy the backpack sprayer having the ability to match these patterns.

The spray nozzles will control the flow rate in tandem with the applicator wand, ranging from 0.25 – 0.5 gallons per minute (GPM). While for professional tasks & heavy-duty spraying jobs, you need a sprayer with nozzles accommodating high volume.

In some cases, gardeners go away from the standard spray nozzle they are using. While farmers and professional landscapers consider buying some extra high-performance nozzles for their spraying tasks. While replacing the nozzles, one has to read the manufacturer’s instructions to adjust the spray patterns as suggested.

7. Chemical Rating:

Various herbicides and other chemicals are corrosive. So, one should choose the sprayers designed to handle these chemicals effectively. Also, check the hoses, seals, and all other accessories of the unit to know whether they are perfectly rated for herbicides to use the equipment effectively.

8. Safety:

Though safety is a major concern for everyone, yet the safety of backpack sprayers is imperative. Usually, sprayers are equipped with tight-fitting straps and lids to have better control over the sprayer.

It is ideal to use lids with at least an opening of a 4-inch diameter, as it allows the product/spray to be poured safely into the container. But clean off any product spillage outside the sprayer immediately for better results.

Prefer to choose backpack sprayers having trigger guards or lock mechanisms, as this safety feature allow the user to depress the trigger for proper application of the product and thereby deter any accidental discharge of the product.

It is a must to wear a face mask and follow all the necessary safety procedures recommended by the manufacturer in its manual. Also, irrespective of the sprayer you are using, you have to rinse its tank at least three times after its usage.

9. Lockable Shut-Off Mechanism:

Usually, a lockable shut-off mechanism is placed on the handle. It allows the user to control the release of any chemicals or liquids and thereby averts from dripping, especially when you don’t want them to drip/release those liquids.

10. Improved Shoulder Straps and Harnesses:

However, the straps, harness, and padding will make a lot of difference in operator comfort, especially, while spraying for long periods.

  • Waist Strap – It is an essential feature to check before buying. The simple shoulder straps suit perfect for light packs, backpack sprayers require better control and a comfortable fit for long hours spent spraying. A waist strap distributes the load across the hips for better control over the sprayer and shares some of its load from shoulder straps.
  • Padding – A good padding and extra lumbar support are essential to consider for landscapers while buying the sprayer. It helps to reduce user fatigue and thereby allows to cover more area in less time. It is essential for those using them for an extended period, yet not required for home gardeners who use/spray them for a few minutes.
  • Harness – It distributes the unit’s weight evenly when the tank is full and thereby make the user feel comfortable. Also, the sprayer needs to deliver the same levels of support, as the tank empties and starts to lose its weight over time. In most cases, the tank is contoured to make it easy to sit across the back. Also, the adjustable harnesses will make it fit properly on the user body.


Some sprayer models feature a full-size handle, gentle grip, and padded straps for the wand. These are all designed to increase comfort by reducing the fatigue and risk of exposure to chemicals than the unit not having these features.

11. Holding Tank Material:

A high-quality backpack sprayer is equipped with durable tanks made of high-density polyethylene. Simultaneously, they feature UV protection, which means the contents won’t get heated and risk degradation or combustion for a proper boost of safety and durability.

Here a translucent tank of the sprayer will make it easy to use, as it allows you to see through the layer rather than having to look through the tank’s mouth.

12. Easy to Clean:

The wand and pack are easy to store and has to be maintained & cleaned quickly after each application. Few backpack sprayers are a bit complicated to clean, which results in cross-contamination and other problems. So, it is essential to choose a backpack sprayer that is easy and quick to clean without giving any excuses for not instant cleaning.

13. Storage:

Storage is another essential feature to check before making a purchase. If the tank or hose get punctured, then you have to repair them before their storage. Improper storage will make these repairs/leaks much faster than we expect. Either home or vehicle, where you are using this sprayer for work, won’t have much storage space, then go for the smaller model.

14. Weight:

The weight (either lighter or heavier) of the backpack sprayer is based on the type of material used and the size of the holding tank. It weighs more while carrying a full tank. Contractors and landscapers get benefitted from a model having a large holding tank to cover large areas (like farms or estate plots) at once. While an average horticulturalists or backyard vegetable garden require a unit with a lighter weight tank.

15. Body Construction:

The body construction of a given backpack sprayer model matters a lot. Since more than 80% of these sprayers are made with plastic, while the remaining are made of stainless steel. However, the plastic made sprayers are easy to clean and last longer (not as steel). Stainless steel is also a good option yet a bit expensive than plastic ones.

16. Purpose:

Though backpack sprayer is a versatile tool that offers multiple functions, yet not all sprayers are designed to perform everything. Moreover, some are efficient at uniform spreading of the chemicals, and others won’t. Also, some models have low-pressure PSI that produces weak and soft sprays for saturating smaller regions, while backpack sprayers with higher PSI are better to spray over long distances, yet might damage the grass.

So, it is essential to identify the purpose of using this backpack sprayer to grab the most suitable sprayer.

17. Durability:

If using the sprayer regularly, then check for a reputable brand that offers durable and quality products. Also, look for a pump that dispenses liquids for a longer time. Ensure that tank is made of high-density materials (like polythene) and also inspect other parts that include hoses and seals before purchasing.

Also, pick a model or brand in which its replacement parts should be easy to find (available everywhere). It is quite helpful while considering a battery-powered sprayer having an electric pump.

18. Other Features:

Backpack sprayers come with a variety of different features, including a built-in pressure gauge to monitor the pressure of the sprayer when using, and a fold-away pump handle that won’t get in the way while spraying.

Larger models offer wheeled cart and extended hose that is used for heavier tanks and complex yards. Some sprayers are equipped with filters and screens that keep the dirt or debris out from the nozzle. The O-ring, gaskets, etc. will work for chemical resistance.

19. Price:

Investing in a good-quality backpack sprayer is a bit expensive, yet works well for a longer time. If not interested in spending more money on your first sprayer/having a small garden area, then opt for small budget sprayers. Few sprayers that range from $30 – $80 having excellent facilities and features. Among them, a few offer warranty services.

How to Use a Backpack Sprayer:

Proper usage of backpack sprayer will increase the efficiency of its application and thereby keep you safe and extend the life of the sprayer. So, it is essential to keep in mind the following process before starting.

  • Irrespective of the liquid you are using (water, chemicals, pesticides, herbicides, or liquid nutrients), the usage instructions are the same. We advise not to use the same sprayer to apply a non-selective herbicide and any other product, as it results in cross-contamination.
  • Ensure to wear recommended safety gear and read the manual carefully before starting the process. Regulate correctly with water before filling the tank. Here is the step-by-step procedure that let you know how to use this sprayer effectively.
  • Set the unit properly by inserting the pump handle in its location, fasten the shoulder straps, and attach the spray wand onto the spray gun.
  • Prepare a liquid mix in a separate container rather than in the tank for bucket test, while mixing the herbicides, pesticides, or insecticide with water. Read label instructions while mixing chemicals and work in an area where potential spills won’t harm plants. As chemicals are concentrated and one should not mix them stronger than recommended.
  • After diluting or mixing the chemical, one has to pour the mix slowly inside the tank. Don’t drip any chemicals on the ground or yourself while pouring.
  • Tighten the screw lid on the tank, place the sprayer onto the back and tighten all straps to secure the sprayer and fit snugly.
  • Ensure to pump the handle 10 – 15 times and do pumping every 5 seconds to maintain constant pressure inside the backpack tank. If not done this step, then prime the sprayer each time whenever the pressure goes out. Also, ensure the battery is charged fully while using a powered type of sprayer.
  • Now you are ready to use the sprayer, all you need is to point the wand to spray and pull the trigger. Cover all the plants or places where you want to spray.
  • Once done spraying, ensure to clean the sprayer (both inside and outside parts) thoroughly by disassembling them to clean every part effectively.
  • Don’t forget to re-assemble the backpack sprayer before recharging the battery or storing them. The sun’s UV radiation may damage the plastic sprayers if left outside in the sun. So, don’t leave them in the sunshine.

Safety Tips:

Safety is extremely essential while dealing with chemicals. Here are the safety tips to be followed for the safe and effective usage of these backpack sprayers.

  • Inspect the entire sprayer pump for any cracked hoses, damages, or leaks before you start using them.
  • Make sure to mix the chemicals as per the label instructions (in recommended quantities).
  • Wear proper PPE (personal protection equipment) that includes chemical-resistant gloves, eye protection goggles, clothing that covers arms and leg area, and a respirator (if needed).
  • Be cautious while walking and prevent steeping on chemicals to avoid hazards.

Ans: The holding tank of the backpack sprayer is not under any pressure, which means it is safe to wear and use without causing any threat of the tank exploding. Here the pump will create the essential pressure required in a separate chamber by relying on a diaphragm or a piston.

A diaphragm pump will push the air into pressurizing chamber similarly as blacksmith’s bellows. While a piston pushes the air into pressuring chamber similarly as a bicycle pumps air forcibly into tires. The piston starts generating friction when it moves in the cylinder. If the spraying liquid has any particulates, then the friction results in rapid wear of the system. While diaphragm pumps won’t have any moving components, and thereby won’t produce any friction.

So, thus lacking in creating friction will reduce the wear and tear on the machine and thus extends their life service.
