How To Select The Best Backpack Sprayer(s)
It’s important to understand – all sprayers are not created equal. In fact, they come with a wide variety of options and variations.
To be sure of getting a sprayer that fulfills its intended use and provide you with the most value for your dollar, there are some considerations you should keep in mind. Among them are:
- The ability to modify or upgrade the basic unit
- The size and terrain of the area for treating
- The level of effort involved in operation
- The amount of maintenance involved
- Availability of replacement parts
- Typical Usage
- Sprayer Tank Volume
- Pump Type
When selecting a sprayer for your home, yard, garden, acreage or commercial use, it is important to consider all the tasks at hand.
If you use a variety of chemicals in several different settings, you may need to invest in several different types of sprayers.
Using several sprayers help prevent co-mingling potentially dangerous chemicals and ensuring you use the most efficient equipment to perform your tasks.
A Good Sprayer Saves Time & Effort
There are many benefits to using a backpack sprayer in the home, garden, farm and commercial settings. Among them are:
- Makes spraying for an extended period (30+ minutes) easier.
- Makes it possible to carry a substantial amount of liquid.
- Provides easy control of application pressure.
Inexpensive, easy-to-use backpack sprayers are a superb solution for hobby farmers, home gardeners, small businesses and weed and pest control operations.
Because of their low price, you may wish to purchase separate sprayers for a wide variety of uses, such as:
- Wallpaper removal
- Mildew control
- Killing Weeds
- Insect and Pest Control
- Deck cleaning
These are just a few tasks you can make easier with a dedicated high-quality backpack sprayer.
Be sure to read all of the information pertaining to the sprayer you plan to purchase to fully understand the model’s uses and care requirements.
Piston & Diaphragm Pump Comparison
Backpack sprayers are available in two basic styles, piston pump, and the diaphragm pump.
The piston pump style usually produces much higher pressure, but it is a sensitive mechanism intended for use with only non-abrasive solutions. Solo makes best selling piston pump sprayer.
A diaphragm pump does not typically produce as much pressure as a piston pump, but it is more durable and can be used with a wide variety of herbicides, pesticides, and other chemical solutions.
Although you can get more pressure (up to 90 psi) using a piston pump, you cannot use as wide a variety of chemicals. This type of pump works with a pumping (up and down) motion inside the chemical tank.
This hand pump motion forces the chemical into the spray wand and allows you to apply it. Unfortunately, abrasive chemicals destroy the piston, so this type of backpack sprayer must be used to disperse only non-abrasive chemicals. If you purchase one, be sure to read and follow all instructions very carefully.
Most popular brands of backpack sprayers (e.g. Field King, Chapin, and Solo) offer diaphragm pump spray units. This is usually the best option in any brand because the diaphragm pump is durable and easy to use.
You can use this type of sprayer for both liquid and wettable powder (WP) applications. Piston backpack pump sprayer cannot handle wettable powders as these powders cause excessive wear and tear and early breakdown.
Diaphragm pumps do not have internal cylinders. With the pump handle as you pump, the movement of the diaphragm causes pressure. This type of pump can be used with herbicides (weed killers) and other abrasive type chemicals.
No matter which type you choose, you must be sure to clean the unit thoroughly after every use by dispersing about half a gallon of clean water through the unit.
Backpack Sprayer Design
Backpack sprayers typically have a large (2-6 gallon) high-density polyethylene holding tank and a small interior tank in which the contents gets pressurized. In this spray tank pump compressed air is implemented to release contents when you engage a trigger. Sprayers may be manually pump powered, battery powered or gas powered.
You can get manual hand pump sprayer in back pack sprayer models; however, there are many good reasons to choose a powered sprayer. In addition to the many different attachments and options you can select when using a powered sprayer, you can also enjoy these benefits:
- A power sprayer makes it easy to take care of spot applications quickly or cover large areas with a minimal investment of time and effort.
- Power sprayers can usually accommodate even more liquid than non-powered sprayers.
- Powered sprayers typically have more optional attachments than non-powered sprayers.
- You can choose from battery powered backpack sprayer or gas powered options.
What You Need To Know About Battery-Powered Backpack Sprayers
A pump type sprayer can be very tiresome if you have a large job ahead of you. A good, battery powered sprayer can save your arms and hands as well as a large amount of time.

What You Need To Know About Gas Powered Backpack Sprayers
A gas powered backpack sprayer or motorized backpack sprayer can generate more volume than a battery powered one. This is very helpful when you need to disperse a lot of solution over a large area quickly.
A gas powered sprayer also generates quite a bit more power than an electric one. This is good when you need to reach high places or clean dirty surfaces.
If use your sprayer in a remote area, naturally a gas powered sprayer is more portable since you can carry the fuel along and will not need to recharge it.
On the downside, a gas powered sprayer may be a bit more costly to purchase and to run. Operation cost is greatly dependent upon the price of gasoline.
A gas sprayer is a bit larger and may present more storage challenges and hazards since it uses a flammable fuel. You will need to keep gasoline and oil on hand, and this can be hazardous.
Maintenance can be a bit more challenging since you will need to check and replenish the oil and keep the motor tuned.
Gasoline engines are noisy and polluting, and breathing the fumes may be hazardous to the operator. Even so, for some heavy tasks, a gasoline powered sprayer may be your best bet.
What Spray Tank Volume Will Work Best For You?
Keeps these things in mind when selecting tank size. Not the least of these is your own strength! While it may seem smart to choose a sprayer with a 6-gallon capacity so you can cover a lot of ground, you may find carrying 6 gallons of liquid comfortably on your back for any length of time (or at all) difficult.
When choosing tank size, carefully weigh and consider the amount of area you need to spray, the amount of weight you can comfortably carry and the type of application you will typically pursue.
Standard tank sizes are two, three, four and six gallons. Clearly, if you err toward a tank that is too small, you will waste a lot of time refilling it. If you err toward a tank that is too large, you may end up wasting product and possibly injuring yourself.
Overall, the four-gallon tank seems to be the most popular choice. This size tank is large enough to accommodate most jobs and still light weight enough for most people to be able to carry comfortably.

The makers of backpack sprayers typically take steps to ensure the ease and comfort of the users. This means the sprayers have become more adjustable and adaptable. Additionally, many sprayers can be improved and upgraded with optional parts and universal adaptations. Here are a few things you may wish to consider when purchasing or customizing your sprayer.
Comfort: Be sure that the shoulder straps and waist belt that come with the sprayer you are considering are well padded and able to accommodate the weight of the tank comfortably. If the standard straps are not adequate, find out if the manufacturer offers an upgraded option.
Spray Wand Length & Type: It’s important that the unit you choose has a high-quality wand of the right length for your use. Otherwise, you will encounter a great deal of frustration as you try to accomplish your tasks.
If the spray wand is too short or too long for the purpose at hand, you will have difficulty attaining accurate application results. If the unit you purchase does not have an appropriate spray wand for your use, you should be able to switch it out.
Poor quality spray wands may tend to leak. Look for one made of high-quality plastic, metal or stainless steel, and can be outfitted with TeeJet spray nozzles. These adjustable nozzles make it possible for you to perform a greater number of tasks.
Some spray handles include a small pressure gauge so the operator will know the psi.
A backpack sprayer is a simple tool helpful in making a wide variety of tasks easier; however, don’t let the simplicity deceive you. Using a sprayer incorrectly can be dangerous. Coming in contact with the solution directly, through blowback or overspray can be quite damaging. Failure to follow manufacturers instructions can cause damage to the unit.
Avoid Leaking: A well-made sprayer is designed so only aspects of the unit resistant to insecticides and chemicals will come in contact with the solution being sprayed; however, some types of sprayers have problems with the seals around the lid on top.
When this happens, the spray material can leak out onto your clothing and skin. Be careful to maintain an upright posture when spraying and be sure to wash off any spills right away and practice personal protection.
Oil Resistance: If you plan on using basal oils to control woody plant overgrowth, be certain all parts of the sprayer can resist an oil-based carrier. If not, the oils will gradually destroy the sprayer components.
Taking Care Of Your Backpack Sprayer
A well-cared for sprayer can provide many years of good service; however, neglecting your sprayer you see it break down in astonishingly rapid fashion. Be sure to empty the sprayer at the end of each day’s use. Dispose of or store any leftover spray solution correctly. Run at least half a gallon of fresh, warm water through your sprayer to wash it out thoroughly.
If you store your yard and garden equipment in an unheated outbuilding in winter, be sure to follow manufacturer’s instructions to winterize your sprayer.
Generally speaking, you would put antifreeze in the tank to prevent damage; however, double-check to be sure this is in compliance with instructions for your specific unit. Better still, store your sprayer in an area where it will be safe from freezing.
At the end of winter, you will want to be sure your unit is ready to get back to work. Clean it and lubricate O-rings and seals as recommended by the sprayer manufacturer. If you use your unit a great deal, you may need to lubricate again one or more times during the growing season.
The Right Equipment Lightens Your Workload
When you take the time to evaluate your needs and select your backpack sprayer(s) carefully, you can be sure of lightening your workload and working more efficiently.
Good choice and proper technique add up to savings in time, money and frustration. Using the right sprayer for the right task minimizes waste and increases effectiveness. Good equipment is safer and easier to use.
Before taking on any spraying task, thoroughly read and understand the instructions that come with your equipment. Also be certain to read the mixing and measuring instructions and all precautions that come with any chemical, fertilizer or other solution you may use.
