Roundup Pump Sprayer Not Working

Roundup 2 gallon Sprayer Parts Diagram

The diagram below is the parts of a Roundup 2 gallon sprayer.

The black plastic tube is the sprayer hose that attaches to the pump and the water reservoir.

The round valve on top of the black plastic tube opens when you turn it clockwise, releasing pressure in order to fill your sprayer with water.

The white plastic handle at the bottom of the black plastic tube is what controls the flow of water from your sprayer hose into your desired area.

The blue rubber cap on top of this white handle is what makes sure that no air enters or leaves through this opening and will also help prevent leaks when you’re not using your sprayer for a long period of time.

There are a few possible reasons why the pump sprayer might not be working. One of the most common is that the spray nozzle might be clogged with dirt or debris, preventing it from spraying water.

Another reason is that there may be a blockage in the hose which prevents water from reaching the spray head. A third reason is that there may be an air leak that allows air to enter and prevent water from entering.

If you have determined that your pump has a blockage or there is an air leak, you can fix these problems by trying to clear out any obstruction in the hose and making sure no more air enters it.

Spray the wand with a small amount of water.

Make sure the sprayer is fully connected to the trigger handle, making sure there are no kinks in the hose.

Check for obstructions on the nozzle end of the wand and make sure it’s clear from dirt or debris that may be blocking flow of water through it, as well as clogging up the sprayer’s filter screen if one is present.

Refilling Process: How to refill roundup sprayer?

When refilling your compression sprayer, simply unscrew the cap to release the pressure. Then, the pressure valve will open automatically to prevent accidental spray. The sprayer also comes with a no-spill semi-translucent funnel top tank with an easily visible liquid level and a comfort-grip pump handle for easy operation. A one-gallon tank is a much eligible item than a 2-gallon tank.

This polyethylene plastic tank sprayer lasts for hundreds of spray sessions, and its affordable price is great compared to other types of sprayers.

Turn the machine off by unplugging it from the wall and removing the top cover.

Remove the screws that hold the reservoir in place and remove it.

Locate the refill tube and unscrew it from the base of the reservoir.

Fill up the reservoir with water until it is full, screw on the refill tube, and replace the top cover.

Replace the screws that hold the reservoir in place and plug in your machine to power it on.

A popular plastic garden sprayer, the Roundup garden sprayer is lightweight and simple to maintain. Wash and rinse your sprayer after each use, and check the condition of its gaskets and O-rings periodically. Damaged gaskets or O-rings won’t hold pressure, letting pressurized air or droplets of spray mixture escape. A large leak can render the sprayer useless.

All the seals – O-rings and gaskets – should be replaced at the same time, particularly if toxic chemicals are used in the sprayer. Replacing the seals is a simple task. Roundup garden sprayer repair kits containing all the necessary gaskets and O-rings are available from the manufacturer and wherever the sprayer is sold.
