Garden Sprayer Repair


Garden sprayers allow gardeners to efficiently and accurately spray large quantities of herbicides, fertilizers and other chemicals on their lawns and gardens. These sprayers must resist any interaction with the chemicals. Despite this, many sprayers lose their pressure and sometimes completely lose their ability to spray. Proper maintenance can sometimes prevent this, but other times you will need to take apart your sprayer and perform repairs with a kit.


When repairing the garden sprayer, you may need to completely replace a broken part. You will need to know the parts that come with the garden sprayer. Garden sprayers have a sprayer extension rod that allows the gardener to apply chemicals in hard-to-reach areas without accidentally spraying herself. The sprayer comes with nozzles that control the direction of the spray so that the gardener can hit specific areas or release the chemicals in a broader and more even spray. Poly shutoff valves start and stop the flow of chemicals. Unit pumps provide the mechanical action that guides the chemicals. The sprayer also has a tank that holds the chemicals until the gardener sprays them.

Repair Kits

Vendors often sell repair kits for garden sprayers. These kits fix pumps that have lost their ability to generate pressure that allows the gardener to release the chemicals. The pressure problem might come from the o-ring in the gasket or in the pump.

Repair Process

You will unscrew the pump assembly, disassemble the pump, pry out the o-ring, add a new lubricated o-ring, remove the wand and replace the o-ring between the wand and the gasket. Sometimes, the problem may come from a kink in the hose, which you can repair by cutting out the kink and reattaching both ends of the hose. The kit comes with a clamp for sealing both ends.


Garden sprayers need proper maintenance to maximize the lifespan of the sprayer and minimize repairs. You should let all the air out of the garden sprayer by pulling the air release spout. Lubricate the gasket once or twice a year right before the spring to ensure that the gasket does not experience friction, which can distort the gasket and ruin its operation.


Every two or three times you use your garden sprayer, you should clean out the extension wand and the hose to prevent damage to either of these parts. You can clean out the chemicals in the garden sprayer by purchasing products designed specifically for cleaning out herbicides. Let the cleaning chemicals sit in the tank for the time frame recommended by the product, and then spray out the cleaning chemical. This prevents chemicals from interacting with each other if you use a different brand the following season and also prevents chemical breakdown in the garden sprayer.
