FAQ
What type of liquids can I use in this tank?+
This 3 Litre tank is primarily designed for use with concentrated liquid weed killers and pest control solutions. However, always check the product label to ensure compatibility with plastic before use - particularly with acidic formulations.
How do I clean the tank after use?+
Thoroughly flush the tank with water immediately following each use. Avoid using harsh chemicals or solvents that could damage the plastic. Rinse repeatedly until all traces of the solution are gone.
Is this tank suitable for spraying delicate plants?+
While designed for general garden use, avoid prolonged contact with delicate flowers and seedlings. Dilute your spray concentrate appropriately to minimise potential damage.
What material is the tank made from?+
The tank is constructed from high-density polyethylene (HDPE) plastic - a durable and weather resistant material suitable for outdoor use.
How does this tank compare to hand pump sprayers?+
This 3 Litre tank offers more capacity than smaller hand pumps, reducing the frequency of refills. It also provides greater control over spray volume compared to some basic hand-held options.
Does the tank have a measuring scale?+
No, this model doesn’t include an integrated measuring scale. Accurate dilution is crucial; always follow the manufacturer's instructions for mixing your solution carefully.
How does it handle pressure?+
The tank is designed to withstand typical pressures generated by manual pumping. However, avoid over-pressurising – do not use excessive force when pumping.
What size nozzle would you recommend?+
A standard 180-degree spray nozzle is generally suitable for most applications with this tank. Adjust the nozzle distance to control spray pattern and coverage.
Can I store the tank outdoors?+
Yes, it's designed for outdoor storage. However, avoid prolonged exposure to direct sunlight which could cause slight warping of the plastic over time.
What is the maximum operating pressure?+
The tank is rated for a maximum working pressure of 3 bar (43 psi). Exceeding this pressure can compromise the structural integrity of the tank.
