Things To Consider When Buying A Weed Sprayer

Buying a weed sprayer should not be done out of whim. Each weed sprayer comes with features and designs that are made for specific purposes. Having to know these considerations will help you make a more accurate decision regarding your ideal weed sprayer.

Type Of Pump Mechanism

Sprayers are designed with specific pumping systems are usually categorized by piston pump sprayer or the diaphragm pump sprayer system.

The piston pump is easily recognizable because it is the more traditional type of pump requiring the up and down movement to pump fluid out of the tank. While this is the more ‘manual’ type of pump, it actually delivers a good amount of sprays and pressure when spraying.

On the other hand, sprayers making use of a diaphragm mechanism can provide you with other features which can be more costly than piston pumps. It works the same way as the piston pump but is devoid of the cylinder in its system. It is designed with a diaphragm that accumulates pressure to pump fluid out of the tank.

While diaphragm sprayers provide a stable amount of pressure, they can be quite hard to maintain and clean.

Manual Sprayer And Motorized Sprayer

There are two options to go with when considering a backpack weed sprayer – you can go either with a manual or a motorized sprayer.

Manual or traditional sprayers are the common types of sprayers that are operated using a hand pump with the usual manual pumping action to pull the fluid out of the tank to the spray nozzle.

While this can be a much affordable option, it actually requires constant pumping which in long run can be a bit daunting.

Motorized sprayers on the other hand are the automated types of sprayers. It makes use of a motor that is powered by a battery and delivers continuous sprays without the need for pumping action.

While this option provides better comfort and convenience, it is actually a bit pricier and substantially heavy because of the added battery on its components.

Comfort And Safety

Many weed sprayers are equipped with safety features along with accessories and add-ons that provide comfort when using the equipment. Among those popular safety and comfort features that are found in backpacks, sprayers include the harness, padded straps, adjustable handles, and nozzles.

As you consider these added features, ensure that you can afford the increase in price seeing that adding more features also means increasing the unit’s price.


Of course, when you want your weed sprayer to last for a long time, you need to make sure it is made from high-quality and durable materials. Most of the common sprayers with reliable durability are made from high-density polyethylene with UV protection.

Also, ensure that your weed sprayer is leak-proof and can withstand corrosive chemicals that are used in gardening.

Shut-Off Mechanism

If you want to conveniently control the release or volume of sprays out of your sprayer, you should look into buying a unit with a good shut-off mechanism. Not only can this mechanism help you deliver a more accurate spray but can also relieve you of drips from the nozzle.

If you don’t want any chemicals wasted or dripping off your spray nozzle, you can find a weed sprayer with a reliable lockable shut-off mechanism.
