Backpack Sprayer Buying Guide

Things to Consider

backpack-sprayer1There are several things that you will want to consider when searching for the right backpack sprayer for your needs. These considerations will help you sort through all of the choices so you select the one that is going to meet your needs the best.

  • What will you be using it for? – Knowing what the primary use is for the backpack sprayer will determine which models are better suited for your needs. A good example of this is if you are going to be using a lot of oil-based products. If this is the case you would want to look for a sprayer that has seals, hoses and pumps that can resist oil based carriers. You want them to be durable and able to handle multiple applications.
  • Manual or motorized sprayer? – If you are treating new infestations you will want to get a manual sprayer that offers a switchable handle that can be used with either the left or right hand. If you are going to be treating larger areas, you will want to opt for the motorized model so you don’t have to maintain pressure on the handle like you have to do with a manual sprayer. The drawbacks to motorized sprayers that you will need to take into consideration is the extra weight, extra cost and extra maintenance they require when compared to manual models. If you do choose the motorized model, look for a battery that can handle low and high psi output easily and that will work for at least 3-5 hours on one charge.
  • Pump type – There are two types of pumps that a backpack sprayer will come with: a piston pump or a diaphragm pump. Piston pumps are the least expensive but don’t always work with all types of herbicides. The piston pump can wear out faster and need replacing if you are using dry herbicide formulations often. Diaphragm pumps are more durable with different herbicides and are easier to repair as well making them a more popular choice in general.
  • Safety considerations and comfort – Things like a spray wand grip and pumps that are full sized are features that help reduce fatigue when using the backpack sprayer. Other helpful features include adjustable padded straps that are resistant to chemicals. Contoured tanks provide a better fit for the user as well. You can purchase another harness if you like certain features of a sprayer but don’t like how the harness fits. You also want to look for sprayers that have Viton rubber seals that resist softening and swelling due to the chemicals which can cause leakage and pump breakdown.
  • Spray Wand – A good quality spray wand will not be prone to leaks and is very important for user comfort and accurate application of the chemicals that you need to apply to your trees, shrubs and other things. You also want to look for sprayers that accept TeeJet nozzles which give you a huge assortment of professional grade tips from local suppliers.

  • Nozzle Selection – There are many different types of nozzles but the most commonly used are the cone, fan, direct stream, and adjustable. The type of nozzle you are using affect’s the pressure output as well as the size of the area that you are able to spray. Nozzles also affect the type of spray, ranging from a fine mist to a steady stream. Pay attention to the material a nozzle is made from. Plastic nozzles are going to be the least expensive but usually degrade over time. Nozzles made from bronze, brass, or nickel are more expensive but these nozzles last for years which make them worth the extra upfront cost.
  • Warranties – Warranties are very important to the longevity of your sprayer. Eventually things will wear out and you want a good warranty in place to cover defects. Most warranties do not cover wear and tear so if you are able to find a warranty that covers anything besides manufacturer’s defects, jump on it. Check to see if the company offers accessory kits that include things like nozzles, hoses, O rings, valves and other parts that will need replacing at some point.
  • Durability and Easy Repair – Look for backpack sprayers that are constructed from high-density polyethylene along with UV protection. Make sure the hoses, accessories and seals are rated to handle additives and herbicides. You also want to make sure it is easy to find replacement parts when needed.


There are some additional accessories that you might want to consider adding to your backpack sprayer to make it even better and easier to use.

  • Shut off mechanism at the tip – This is a great feature that can be added to the existing factory wand. This feature gets rid of unwanted dripping of chemicals.
  • Wand Extensions – You can purchase wand extensions that are either curved or straight and that measure up to 48”. The longer wands extend your reach which makes the work is easier.
  • Pressure Regulator – This device can be added to the spray wand and helps to maintain a constant spray pressure. It allows for a more consistent application and prevents problematic pressure spikes and product drifts.
  • Quick Couplers – These handy little accessories allow the spray wand to be removed quickly so storage and transporting the backpack sprayer is much easier.
  • backpack-sprayer3

  • Improved and Better Harnesses – A good quality harness that is adjustable with padded shoulder, chest and waist straps as well as waterproof pads to prevent the chemicals from getting on the user are all excellent qualities for a harness to have.


A backpack sprayer is a convenient and useful item to have around so you can grow a successful garden, shrubs or trees. You are the one that can determine which model is going to be the best for your specific needs.

This guide is designed in a way that you have the information you need on what to consider and how to choose which one will be the best.

When you are going over the different features, tips and options don’t forget to think about how much pressure you want in the tank, how big the tank needs to be, the length of sprayer hose you want and how easy replacement parts are to find.

Purchasing the right backpack sprayer is a big decision that when chosen correctly, saves you time, money and improves the quality of your lawn, trees, shrubs, flowers and anything else you want to grow.
