Full details
The My Garden Outdoor Living 20-Litre Knapsack Pressure Sprayer is an essential tool for homeowners and professional landscapers looking to maintain large gardens, greenhouses, and patios with efficiency. It excels at applying fertilizers, herbicides, and pesticides over expansive areas due to its large capacity, though users should be mindful that a full 20-litre tank can become quite heavy for smaller individuals to carry over long sessions.

FAQs
Can I use this for harsh chemical cleaners?
While the unit is durable, always check your chemical manufacturer's instructions to ensure the liquid is safe for use in plastic knapsack sprayers.
How do I maintain the pump mechanism?
Keep the pump lubricated if recommended by the manual and ensure you flush the unit with clean water after every use to prevent mineral or chemical buildup.
Is the lance detachable?
Yes, the 60cm lance can be detached for easier cleaning and compact storage.
Can the straps be adjusted for different body types?
Yes, the twin shoulder straps are fully adjustable to ensure a balanced fit and comfortable weight distribution.
Does this sprayer require electricity?
No, this is a manual pressure sprayer that relies on your physical pumping action to generate pressure.
What is the best way to store the sprayer for winter?
Thoroughly rinse the tank, pump, and lance with warm water, ensure the unit is completely dry, and store it indoors to prevent freezing damage.
Troubleshooting
Weak or no spray output
Check if the pump is primed or if the nozzle is clogged with debris; clean the nozzle with a soft brush.
Pressure loss during use
Ensure the lid is screwed on tightly and the pump handle is functioning correctly to maintain an airtight seal.
Leaking from the lance connection
Tighten the connection point or inspect the rubber O-ring seal for damage and replace it if necessary.

Setup, Compatibility & Care
Before your first use, ensure all seals are securely tightened to prevent pressure loss. The sprayer is compatible with most water-based fertilizers, herbicides, and pesticides; however, always verify chemical labels for compatibility with plastic sprayers. After each use, flush the system with clean water to prevent chemical buildup in the nozzle or internal lines. Store the unit in a cool, dry place out of direct sunlight to protect the integrity of the tank and plastic components. Periodically check the shoulder strap buckles for wear and ensure the lance connections remain debris-free.
