Buying guide – What to look out for when buying a backpack sprayer

Before you buy a backpack sprayer, it makes sense to look out for some important things such as tank capacity, maintenance, flexibility and body construction.

Tank capacity

It cannot be guaranteed that all tanks will be fatigue-free. So, the bigger the tank, the higher the chances of causing fatigue. It makes sense to look for a tank with less weight in order not to be fatigued. There is nothing wrong in filling the tank as many times as possible as than to have a big tank that will make you go down with chronic back pain due to fatigue. If you have backaches easily, then, a backpack sprayer is not meant for you. You may go for a wheeled sprayer.

Maintenance

Look for a sprayer that is easy to maintenance. Most sprayers require no tools to maintain making it the ideal backpack sprayer for you.

Flexibility

Flexibility is important when you want to buy a backpack sprayer. A sprayer of above 60 PSI is flexible enough to let you reach difficult and hard-to-reach areas. You may need a sprayer with multiple nozzles to achieve more flexibility

Body construction

The body construction of the backpack sprayer also matters. More 80% of the sprayers are made of plastic while the others are made of stainless steel. Plastic backpack sprayers are easy to clean and are made to last a long time. Stainless steel backpack is also great but is more expensive than the plastic sprayers

  • Check the plunger “O” ring by pulling it off and properly inspect it for cracks or split. If it is fine, all you need to do is to lubricate it with grease or Vaseline
  • Try to slide plunger back into the pump housing; line up the two side tabs and once they click that is a sign they are well secured

How to put the straps on a backpack sprayer?

The top of the shoulder straps is pre-attached to the sprayer by means of a buckle or pin. The lower end of the straps is attached by fastening the strap hooks to the metal frame between where the frame exits the plastic tank and where the frame makes a bend.

What to use to clean out a backpack sprayer?

The backpack sprayer needs to be cleaned up after each use. You don’t have to be lazy about. Cleaning it is just a matter of following a simple procedure. Cleaning it once should be enough but if you allow the chemicals to stay in the sprayer for too long, you may have to wash it more than once. Avoid dumping chemical in ditches or on the public waterways. This can have a grave implication on people’s health. Here is how to wash a sprayer:

  • After spraying, clean the tank thoroughly. If some spray liquid is left inside, drain the tank completely.
  • Pumping causes air to be taken in and the remaining liquid to be discharged. Pump until liquid and air are coming out through the nozzle.
  • Refill tank with a few quarts of clean, soapy water and pump the water out as explained above (if necessary, repeat this procedure several times).
  • If the shut-off valve is removed, the pump can be flushed quickly. Improper spray distribution is the result of a clogged nozzle, which is easily removed and cleaned.
  • Soap and water may also be used to clean tank.
  • Do not use aggressive cleaning agents or abrasives.
  • Follow the recommendations of the chemical manufacturer for disposal of wastewater and chemicals.
  • Activated charcoal in liquid or others may be used to absorb chemicals in tanks or spills.

General Instructions

After assembling your backpack sprayer, it makes sense to test it by filling it full of water. This will help you to look out for leakages and test the pressure level. You can then use it after being satisfied.
