How to Buy a Backpack Sprayer for Lawn and Garden

We have considered the above eight backpack sprayers as the top sprayers for parks and gardens.

Here you need to consider some crucial things to check before buying any backpack sprayer. So, let us start with the first one:

Brand Selection

The very first thing to be taken care of while purchasing the backpack sprayer is a reputable brand. Buyers always look for a renowned brand as they offer quality products. If you need to check about the brand reputation, then make sure to view reviews of its products. Buyers’ reviews tell us many things about the brand.

Moreover, accessible and reputable brands serve you good services even when the product gets damaged and is not working correctly. They will ensure the guarantee of replacement and free services. Furthermore, if the worst thing happens, they are also liable for their product.

Motor-Operated or Manual

Now, the second thing a buyer needs to check while purchasing the backpack sprayer is the pump operation system. The backpack sprayers are available in two distinctive forms- one is motor-operated, and the other is manual. Probably, this will depend on the buyer’s choice of preference.

But if one is selecting the motor one, make sure to check the battery back-up and its durability. If someone wants a backpack sprayer for small lawns and gardens, then prefer manual operated and if space is significant, then a motor-operated backpack sprayer is the right option.

Components of the Backpack Sprayers

The next thing to check while buying is the basic features and parts of the sprayer. Generally, all the backpack sprayers have standard components and features like a sprayer tank in which the chemical is loaded, a wand for spraying the chemical, sprayer attachment, and an operation pump.

So, make sure while purchasing a perfect backpack for your lawns that the backpack sprayer is loaded with these essential components.

Additionally, there are some additional features that you can check while purchasing a backpack sprayer, i.e. shutting valve, the battery indicator in the motor sprayer, tank’s mouth area, etc.

The mouth of the tank must be broader enough for easy filling and cleaning. Moreover, you can check the type of material used in the manufacturing of backpack sprayers.

Sprayer Nozzles and Wands

It is one of the most important things to check while buying a backpack sprayer. This is also important to prevent any accidental damage from chemicals. The wands and spraying nozzle should fit appropriately so that no leakage of chemicals takes place.

Be sure while purchasing the backpack sprayer that the nozzle and wand are compatible properly. Always choose the wand which prevents leakage and is spill-proof and properly fits the nozzle.

The Durability of the Backpack Sprayer

When you are purchasing a backpack sprayer, it becomes mandatory to check its durability. Many backpack sprayers get damaged with prolong use of chemicals and also start leaking the chemical from nozzles and wands. Make sure while purchasing the backpack sprayer that is manufactured with high-quality material.

If possible, then always choose a reputable brand as they keep a quality check on the material of the backpack sprayer. Always pay attention to the sprayer wand. It will be able to spill liquid chemicals for a long time without leakage. Your investment should be for a long time rather than a short time.

The tank should be made from high polymers or preferably polythene material for extended durability. The nozzles, seals, and hose should be resistant to damage that may occur from prolonging the spilling of chemicals. Also, make sure that the tank is protected from UV also.

These things should be taken into consideration while purchasing any backpack sprayer. One must buy the backpack sprayer from reputed brands only as mentioned above.

Types of Pump used in the Operation

diaphragm pump and a piston pump


We have already explained above which type of operating system one should use. The next type which we are explaining here is the type of pump used for spraying the chemical. The pump is available in two forms- a diaphragm pump and a piston pump. Once after deciding between motor and manual pump, choosing between a piston and diaphragm pump is quite tedious.

To make your choice a bit easier, here we have explained both the pumps. The piston pump requires manual pumping for generating the pressure. It helps spray liquid chemicals in upward and downward directions. Moreover, it only creates pressure up to 90 psi.

On the other hand, the diaphragm pump also uses the same pressure generation for spilling the chemicals from the sprayer. But the main difference in both of the pumps is that the diaphragm pump can withstand harsh chemicals and is resistant to damage. It is also useful for spilling denser particles for weed control.

However, more features come with more price only. The diaphragm pump is a bit more expensive as compared to the piston pump. But as always, needs come first. Therefore, before munching on any expensive product, make sure to look after your needs. After that, purchase the backpack that suits you the best.

The Functioning of the Backpack Sprayer

Coming to the next thing, which is more important to be taken care of while purchasing a backpack sprayer is its functioning. Many backpack sprayers are for only one-time use and not for multipurpose use.

For example, one backpack sprayer with the diaphragm is perfect for hand trunk trees and can be only used for them, while the piston pump is used for both small and large both.

Furthermore, a buyer needs to buy the one which can be suitable for multipurpose work like spraying chemicals, fertilizers, and water too.

Along with this, you need to pay some attention to the pressure generated by them. A high-pressure pump will be able to spray in a broader area in a single time while a low-pressure backpack sprayer will spray chemicals in a limited space.

Always make your choice by knowing your needs. Check your area and the pressure required for spraying in your area before buying any backpack sprayer. Also, make sure that the backpack sprayer should be functional for a long time.

Check Comfort and Safety

Your safety is most important. Any chemical spill on your skin is vulnerable to cause you damage. Moreover, if a backpack is not fitted with double padded or deluxe straps, then it will be uncomfortable to carry such a sprayer tank on your shoulder for a long time and spray chemicals in your garden.

So, before you proceed for buying any backpack sprayer, make sure it has durable and double layer straps that make it easy and comfortable to pick up. The wands and sprayer should have firm gripping points to add ease in handling the sprayer and avoid any spilling on hand. Also, check that the sprayer is comfortable to handle.

Thus, to prevent any accidental damage, you need to check these safety measures first before buying a backpack sprayer.

Calibration of a Backpack Sprayer

Calibration of the sprayer is also essential to check the efficiency of working of a backpack sprayer. The things that need to be calibrated are the output of the chemical from the spray per minute, the width of the wand, and walking speed. But also make sure to use only water while calibrating the backpack sprayer. Follow this method for calibration:

  • Clean the sprayer and fill it with water first.
  • Now, make two plots of 25m in the lawn area with the help of marker or ruler rods. Also, make a mark on the sprayer tank to fill the water to that level only.
  • Now, spill the water with the sprayer in a marked plot and measure the water level and remaining water in the tank. Fill the water again and cover another area, also with the same speed and pressure.
  • Mark the lots and use the formula for accurate calibration of liquid required and sprayed per minute.

The formula is-

Amount of water used in liters/1000m2 = 40* liters of water used on calibration

Calibration is required to understand the best sprayer and quantity it sprayed in a given time. It is also helpful in knowing how many times you need to refill the tank for your given area.

Picking the right type of backpack sprayer is a tedious job. We often make the wrong choice by having so many features and attractive offers in the market. But, always make sure to purchase according to your needs and make a smart choice after looking into these buyer guide tips.


01. Which Backpack Sprayer is Worth Buying- a Motor One or a Manual One?

Both types of pumps are useful on their own. But as we have mentioned that it will depend upon your need and your garden or lawn size.

If you have a small garden and lawn, then preferably you can have a manual backpack sprayer, but if the area of a park or garden is big, then you can go for a motor backpack sprayer. Most probably, motor pumps are for commercial use.

02. Can I Use the Same Backpack Sprayer for Multi-Purposes Like Spraying Weedicide and Insecticide?

Many backpack sprayers are available for multiple purposes. So, yes you can use both the chemicals. However, some backpack sprayers are not fit for versatile use.

Usually, using a backpack sprayer for two chemicals might have a chance of mixing and causing damage to your plants. But if you are cleaning your sprayer tank regularly and adequately, then you can use them for spraying multiple chemicals.

03. Do These Backpacks Feel Heavy to Carry on Back?

No, these backpack sprayers come with double padded straps, which make them comfortable to carry for the long term. Many brands like solo, round up, and Chapin provides a lumbar support system, which is easy on the back and would not cause any strain while picking it on the back.

Also, always look for reputable brands which we have mentioned above. They are always loaded with a lumbar support system and include double padded straps so that you do not feel any strain on the shoulder and back while carrying the backpack sprayer.

04. Can I Also Use the Backpack Sprayer to Kill the Weed in Between the Flowerbed?

Yes, the backpack sprayers give the facility of reaching to the problematic areas of weeds in between the flower bed. You can use a flat nozzle to target the weed in the flowerbed.

You need to have some precautions while spraying on the weed. Moreover, you can use a sprayer drift guard to reach the problematic areas where weed is growing along with your main crops.

05. How Much Pressure is Needed to Spray on Crops and Which One is Best from a Diaphragm Pump and Piston Pump?

Pressure will depend upon the area of the lawn and how much you want to spray. Many brands offer pressure of a maximum of 150 psi. Regular 90 psi will be suitable for spraying in your regular size lawns. But if you have a big size lawn, then you can have the backpack sprayer which generates high pressure.

Moreover, if you are selecting small size lawn, then a piston pump is good for spraying chemicals. If you are going to purchase a backpack sprayer for commercial use, then go for the diaphragm. For more details, check the buyer’s guide.


Over the last few decades, backpack sprayers have become a vital part of gardening. They are also the most essential tools for spraying weedicides, insecticides, and fertilizers.

Earlier, it was done manually and with the help of hands which caused damage to the skin. But with these backpack sprayers, it becomes easy to spray chemicals in fields and gardens. It adds comfort to the life of gardeners and farmers.

But, many of us still struggle with finding the best backpack sprayer. The reviews about different brands and backpacks given above will make your choice easier. You can choose the perfect one always according to your needs.
