If your Pump Zero Power Spray is malfunctioning or has completely shut down, you’re in the right place. 

This post provides a comprehensive troubleshooting guide to help you identify common problems and find solutions to get your sprayer back in action.

1. The Pump Won’t Start

The pumping failing to start despite turning on the power switch can be caused by several factors:

• The power plug is misconnected.
• The power switch is defective.
• The tank is pressurized so the pump has turned off automatically.
• The battery is not charged.
• The pump is connected to the charger.

You can solve this issue in the following ways:

• Check if the power cord is plugged in correctly and the outlet is functional.
• Open the shut-off (depress lever).
• Charge the battery.
• Disconnect from the charger.

You may need to consult an expert if you detect more problems with the pump motor.

2. The Sprayer Turns on But Won’t Spray

You may turn on your pump and there is an audible hum but it won’t spray. This issue can be caused by a clogged shut-off or nozzle, no liquid in the tank, or if the pump is not fastened to the tank.

Consider these solutions to solve the issue:

• Clean the shut-off or the nozzle.
• Tighten the pump to the tank.
• Ensure you’ve poured the solution you intend to spray in the tank before turning it on.

3. The Sprayer Has Low-Pressure Output

Poor water pressure causes inefficient watering and poor lawn coverage. You may observe this if the sprayer operates but emits a weaker spray than usual or if the spray pattern is inconsistent.

The poor output pressure issue could be caused by issues such as:

• The tank is not yet pressurized.
• A clogged shut-off or nozzle.
• Air leak at the tank seal.

Here are some solutions:

• Allow at least 20 seconds for the pump to pressurize the tank.
• Clean the shut-off or nozzle thoroughly with an appropriate cleaning tool.
• Tighten the pump to the tank.
• Replace tank seals if they are damaged.

4. The Pump is Leaking

If you’ve noticed hose leaks near the tank, nozzle drips when the shut-off is released, or a nozzle tip leak, you could be dealing with a cracked or faulty hose system, clogged shut-off system, damaged O-ring, or a damaged hose-tank connection.

You can try different ways to solve this issue:

• Clean the shut-off assembly.
• Replace the shut-off assembly.
• Install a flat seal behind the nozzle.
• Replace the flat seal.

A pump zero sprayer leak is one of the easiest issues to sort but only if you can identify the problem quickly and timely.  

5. The Battery Won’t Charge

A battery that won’t charge can be indicated by:

• No light blinking on the pump.
• A continuous red light flash that indicates the battery temperature is too high for safe charging.
• Red and green light flashes that indicate the battery cannot be charged.

You can troubleshoot this issue as follows:

• Plug the charge in the outlet.
• Check if the outlet is functioning.
• Replace the charger. 
• Allow the pump to cool down.
• Replace the pump.

How to Maintain a Pump Zero Power Sprayer 

You can prevent many issues if you maintain the Pump Zero Sprayer properly. 

Here are some maintenance tips you can implement:

• Ensure the pump is attached to the tank tightly.
• Avoid placing the pump down where it may collect debris or grass clippings. 
• Allow the pump to pressurize the tank by pressing the power button.
• Charge the battery at least once every 3 months when not in use.
• Don’t use sharp objects to unclog the nozzle.
• Ensure the tank is completely dry before placing it in storage.

Remember that for the sprayer to work efficiently, the two main components, the pump and tank must remain in peak condition. So, please make sure that you follow the maintenance instructions for optimal performance.

The post Pump Zero Power Sprayer Troubleshooting Guide appeared first on InsightWeeds.

In fact, we’ve previously recommended it as one of the best pump sprayers for weeds. And we still think it is worth your money.

Unfortunately, you might encounter a few issues when using the pump sprayer. Noteworthy, these issues are pump-specific rather than design flaws.

Nevertheless, the problems can be pretty inconvenient, especially when you need the pump for time-sensitive tasks such as herbicides or pesticide control.

We have compiled information on troubleshooting and repairing your pump sprayer when it stops working.

Reasons why your Roundup pump sprayer is not working

There are several reasons why your Roundup pump sprayer might stop working.

These include:

1. The lid is not closed properly
2. Wrong pumping mechanism
3. Insufficient levels of liquid in the tank
4. A blocked nozzle
5. Damaged sprayer parts

How to fix a Roundup pump sprayer that is not working?

If your Roundup pressure sprayer isn’t working, the troubleshooting tips below can help you identify and fix the issue:

1. The lid is not closed properly

One of the major issues causing your Roundup pump sprayer not to work might be the tank lid.

The way the sprayer works is that it compresses air in the tank to create pressure. The pressure is then used to move the liquid from the tank out through the nozzle.

If the lid is not closed correctly, the air in the tank will not be compressed, as the pressure will escape. As a result, your pump will not spray the liquid in the tank.

Therefore, before you start pumping, you should ensure that the lid is closed snugly such that the air won’t escape.

Aside from the lid, it is also possible that air could be leaking through the hose, where it is attached to the tank lid.

Like with the tank lid, you need to ensure that the hose seal is secured snugly to the pump, thus preventing air from escaping.

2. Wrong pumping mechanism

Another issue that can cause your Roundup pump sprayer not to work is the wrong pumping mechanism. This is specific to the backpack garden sprayers with piston pumping mechanisms.

With the piston pump, air enters the pressure chamber when you move the lever (pumping handle) up.

Then, when you move the handle down, the air in the chamber is pushed into the tank, creating pressure.

Therefore, to create pressure in the tank, you must move the handle up and down (from and to the highest and lowest points it can go).

Unfortunately, some people make the mistake of pumping from the center position of the handle, which does not create any pressure in the tank.

Therefore, if you have any issues with your Roundup garden sprayers, you should adjust your pumping mechanism and see if anything changes.

With the proper pumping mechanism, the lever becomes harder to move as the pressure inside the tank builds up.

3. Insufficient levels of liquid in the tank

Insufficient liquid levels are another reason your Roundup hand pump sprayer won’t work.

To spray, you must have enough liquid in the tank, which is suctioned out by the pressure created as you are pumping.

As the levels of the liquid fall down, the spray output declines until a point where no more liquid can be pumped out. Therefore, you need to increase the liquid in the tank to continue spraying.

Unfortunately, the opposite can also be an issue, causing the sprayer not to work.

As already stated above, the pump sprayer works through pressure creation, and this can only happen if there is sufficient space for air to be compressed in the tank.

If there is too much liquid in the tank, you won’t be able to create enough pressure, thus causing the spray nozzle not to work. To avoid this, you should not overfill your tank.

Most sprayers will come with a water level where the maximum capacity is marked.

However, if your sprayer does not have a maximum level, filling the tank about three-quarter’s the capacity will work just fine.

4. A blocked nozzle

A blocked nozzle is another common issue that can cause your Roundup pump sprayer to stop working.

The nozzle can be clogged by debris introduced into the tank through water (if you use unclean or unfiltered water).

It can also happen if you allow the nozzle to touch the ground when using the pump, thus clogging the pores with dirt.

Another possible cause of clogging is the solidification of herbicides, pesticides, fertilizer, or other solutions you use with the pump. Again, this will happen if you don’t clean the pump well after using it.

Fortunately, a clogged nozzle is very easy to fix. You just need to unscrew the nozzle and use a needle or a toothpick to pick out any debris blocking the output.

However, when doing this, you should be careful not to expand the nozzle hole, as this can cause it to start leaking when spraying.

Aside from poking the nozzle, you can dissemble the entire hose from where it is attached to the tank.

Then, break the hose down into individual components unscrewing each hose part from the other (you can use the manual to figure out how to unscrew them).

You can now push a high-pressure water stream through each component, unclogging any debris causing the sprayer not to work. After unclogging, re-assemble the hose and attach it to the sprayer.

5. Damaged sprayer parts

Unfortunately, another reason your pump sprayer might not be working is if there are any damaged components.

Some of the most likely components to be damaged include the hose, nozzle, sprayer handle, and pumping mechanism.

Fortunately, fixing some of these damaged parts might be possible by replacing them with spare parts.

For example, you can purchase the Roundup pump sprayer repair kit, which comes with gaskets and O-rings for the pumping mechanism and spare nozzles.

However, you should only attempt to repair your sprayer pump if you know what you are doing.

If not, you should take the pump to the store you purchased it from for repairs or ask for recommendations for a repair technician from your local gardening shop.

Final thoughts

The Roundup pump sprayer is an important tool that can help you in many gardening tasks, such as weeding. Therefore, it can be pretty frustrating when it fails to work.

Fortunately, with the information above, you can identify and fix most of the issues causing the sprayer not to work.

However, if you are unable, you should hire the services of a professional to repair the sprayer for you.

Aside from repairing your pump sprayer, you should also regularly maintain it by keeping it clean, dry, and lubricated.

This prevents damage to important components such as the nozzle, hose, and pumping mechanism, which can be costly to fix.

However, if your pump sprayer is made from quality material, the troubleshooting methods below will come in handy.

The best part is that there are several pump sprayer repair kits available in the market that contain specific parts of the equipment. This will save you from replacing the whole sprayer.

All you need to do is make sure they fit with your model.

Your pump sprayer is not working? Common issues with their solutions

Here are the most common issues that cause your pump sprayer not to work and how you can troubleshoot them.

1. The pump sprayer will not build pressure

Inability to build pressure is arguably the most common problem experienced by gardeners when it comes to pump sprayers. The issue mostly occurs if you have not used the equipment in a long while.

To fix a pump sprayer that will not build pressure:

• Check if the filter needs to be cleaned or replaced. Most pump sprayers come with a filter to sieve off sediments. So whenever the pump pressure is low, Screw off the hose and confirm that the filter is not clogged or rusty. If so, make sure to clean or replace it.
• If the filter is worn out, you need to clean your nozzle. It probably has debris that is blocking the nozzles that should be exerting the liquid. Nozzles are relatively easy to clean. Simply screw them off and brush them over gently with soapy water before screwing them back.
• Confirm that the shut-off valve controlling the filter is open. Some pump sprayers come with a hardly noticeable shut-off valve, so chances are you might have locked it.
• Ensure that the pump sprayer has enough fluid. Naturally, every time the pump sprayer goes below a certain point, the pressure will significantly decrease.

2. Broken impeller

Sometimes the reason your pump sprayer is not working is that the impeller is broken. The impeller spins to generate pressure inside the pump and allows the liquid to be dispensed at high pressure.

In the event that the impeller is not working:

• Disassemble the pump sprayer to expose the impeller. Usually, it will appear as a small propeller.
• Check whether the impeller has a seal as you might have lost it while cleaning. Most pumps cannot work without the said seal, so you will have to replace it.
• If the seal is intact, try turning the propeller to see if anything is broken to replace it.
• Assuming none of the above work, consider cleaning the whole impeller by rubbing it with a wet cloth dipped in vinegar. This ought to remove any dirt and dust buildup.

3. The pump sprayer is leaking

When the pump sprayer starts to leak its contents, it is not only wasting your product but also your time as the pressure keeps dropping quickly.

To remedy this problem, you first need to establish where the leak is coming from. Once you have identified, do the following;

• If the leak is coming from under the cap, the cap is probably loose, or the gasket is damaged. Try tightening the tank cap before replacing the gasket.
• Assuming the leak is coming from the shut-off valve, consider tightening the valve before you resort to replacing the whole shut off valve.
• If you observe the leak coming from the hose, make sure it is screwed on tightly and nothing is broken.
• In the event that the leak is coming from the end of the spray wand, then your O ring is broken, or you need to rebuild the shut-off valve.

4. Check for air leaks

If your pump sprayer seems fine, but it still won’t start working, then there is a possibility that you are dealing with an air leak on the suction pipe.

Often, the said hole is usually tiny to the point that water cannot leak from it, making it hard for you to notice it.

• Confirm that the gasket on the filter is in excellent condition. Otherwise, it will allow air leaks. You can also slather it with grease to help with lubrication.
• Observe the pump sprayer and make sure there is no part that is leaking any fluid.
• Confirm that the tank lip is not broken or feeling loose.
• Tighten every fitting that you can access. This way, you seal off any suction leaks that could be causing you issues.
• Check the condition of your hoses. They tend to wear out fast, especially if they do not come with an embedded wire or plastic coil for extra support.

5. Broken clutch

If you notice that your pump sprayer is not working at all or the pressure is not normal, then chances are you are dealing with a broken or clogged clutch.

Ideally, a clutch is essential as it allows your pump sprayer’s engine to idle without outputting the whole equipment.

If you suspect the clutch is the problem, you need to:

• Disassemble the whole pump in a way that exposes its inside components
• Make sure the part that connects the clutch to the pump is moving smoothly. If not, remnant sediments may be causing build-up.

• If you do not know how to safely detach the clutch from the pump, you have the option to fill up the sprayer with a mixture of vinegar and warm water. Give the solution 40 minutes before pouring it out with any mineral deposits.
• On the other hand, the clutch could be broken. Thankfully you can quickly get a replacement part in your local gardening equipment store.

6. The O ring won’t budge

In order for a pump sprayer to work, then all its ingredients should be working impeccably.

So, if you have been using your pump sprayer for a long time without replacing your O ring, then you need to do just that for it to work in sync with the rest of the machine.

• Check your user manual and confirm the steps you need to follow to take apart the pump sprayer.
• Unscrew the metal cap that is securing the O ring by using a pliers
• Take out the spring.
• Use your pliers to remove the trigger.
• Use a clean cloth to clean out debris and mineral salts that might be corroding the trigger and all the other parts you had removed earlier.
• Plunge the spring, and the gun trigger inside a jar full of silicon oil then spread the oil inside its cavities and the inside of the O rings using your finger.
• Wait for everything to dry up before putting them back together.

7. The pump sprayer won’t stop spraying

If your pump sprayer does not stop spraying the product, even though you have tried switching it off, something is broken.

You will need to:

• First of all, make sure that the wand’s tip is pointed away from any products that you may not want to be sprayed. This way, you do not end up killing all your plants.
• Confirm that the wand is in the off position. If it is not yet you have tried to switch it off, then you need to lubricate or replace it.
• If it starts moving after lubrication, turn the pump clutch anticlockwise while the setting reads down & lock. This will release any pressure inside; hence no more liquid will be forced out.

With these troubleshooting tips, you should now be able to tell why your pump sprayer is not working and how to fix it.

• Ensure the lid is on tight to allow the sprayer to operate well.
• Operate the pump by twisting it to unlock the handle.
• Pump at least 20 times to pressurize the sprayer.

Consider removing any obstacle blocking the nozzle and ensure that you have enough liquid inside the tank.

How do you refill a pump sprayer?

You can refill a high-pressure hand pump sprayer by following the steps below:

• Depressurize the pump sprayer by pushing the handle completely down and turning it anticlockwise until it releases all the pressure.
• Remove the cap from the tank by turning the handle anticlockwise, unscrewing, and pulling it out of the container.
• Pour the liquid herbicide or weed killer into the empty sprayer. Pour slowly to prevent foaming. Avoid overfilling the pump sprayer.

At this point, you can replace the cap and turn the handle clockwise until it is tight.

How to use a pump sprayer

If you are new to a garden weed sprayer, here is how to use it:

• Add the correct amount of herbicide and water into the pump sprayer for the area you want to treat. Leave about a third of the tank empty, so pressure can build up when pumping up the tank.
• Pressurize the tank by screwing the top of the sprayer back on the tank.
• Pump the handle up and down until it becomes hard to push back down.
• Push the handle down and twist it clockwise to lock it in place.
• Adjust the nozzle by rotating the tip of the nozzle.
• You can adjust the spray path to a wide spray pattern or specific stream.
• Apply the weed-killer liquid by pulling the trigger on the nozzle to spray it.
• You can cover a broad area by using a slow zigzag motion back and forth in strips.
• Spray the liquid until you have covered the whole area.

If you run out of the liquid weed killer, refill the tank and continue spraying. Ensure to use protective clothing during the treatment.
