Frequently Asked Questions

Q: What types of bottles does this bottle cap sprinkler fit?

A: The adjustable bottle cap sprinkler is designed to fit most standard beverage bottles, and supports containers with a capacity of up to 20 litres. It works best with standard-threaded bottle necks commonly found on plastic drink bottles.

Q: Can this garden spray nozzle handle fertiliser or cleaning solutions, not just water?

A: Yes! Because it's made from chemical-resistant PP, copper, and iron, this bottle cap sprinkler can be used with diluted liquid fertilisers, cleaning solutions, or plain water — making it a truly multi-purpose garden and household spray tool.

Q: How does the high-pressure manual air pump work?

A: The built-in manual pump allows you to pressurise the bottle by hand before spraying. A few pumps are all it takes to generate strong, sustained water pressure — no electricity, batteries, or external air compressor required. Simply pump, aim, and spray.

Q: Is this sprayer suitable for indoor plant care as well?

A: Absolutely. The adjustable nozzle can be set to a fine mist, making it ideal for indoor plants, humidity-loving houseplants, and delicate seedlings that need gentle, controlled watering.
