Things to Consider When Buying a Backpack Sprayer
Backpack sprayer reviews always come in handy when trying to find one to use in your lawn or garden, but it is always vital to know the things to take into account when making your choice. Although your intended uses are what determine the right backpack sprayer for you, it is also important to consider the following important things before settling on one.
#1. Manual or Motorized
If you want to spray a large area a motorized sprayer will be the best one for you because you do not have to maintain the pressure with your hand. For small areas and new infestations, hand-operated sprayers work just fine, and this is more so if it comes with a switchable handle that you can operate using both the left and right hands.
Also, things like cost, weight, and maintenance should influence your choice because the motorized ones tend to be heavier and more expensive that the manual sprayers.
#2. Pump Type
You will need to choose between a diaphragm and piston pump when buying a backpack sprayer. Although they are both capable of pumping out the agrochemicals, it is important to understand the merits and demerits of each pump so that you can make an informed decision.
Piston pumps are the most affordable between the two but they will not work with some types of herbicides, and they also wear out fast meaning you have to replace them regularly. The diaphragm one, on the other hand, is more durable and will work with almost all types of herbicides. Also, you can repair them quickly.
#3. Nozzles
There are different kinds of nozzles for the backpack sprayer, but the most common ones are the fan, cone, adjustable and direct stream. It is essential to understand that the type of nozzle that you choose to use will not only affect the pressure but also the size of the area that you can spray and the kind of spray that you will get.
It is also important to choose the best nozzle material for the different options available. Plastic tips are quite common and affordable, but they are not very durable. Nickel and brass ones, on the other hand, tend to be pricier but will also last for many years.
#4. Comfort and Safety
Comfort and safety are vital when spraying the chemicals on your plants and so it is important to make sure that you get a unit that guarantees both. A spray wand grip, full sized pumps, and comfortable and adjustable straps are some of the things that help to make the backpack sprayer comfortable. Also, the straps should be chemical-resistant to ensure that it does not get to your body.
To ensure maximum safety, you should also look for a sprayer with Viton rubber seals that are not prone to softening or swelling due to the herbicides as they will prevent leakages and ensure that the pump does not break down.
