New bottles frequently produce nothing for the first several squeezes, which is normal rather than a fault.
First-Use Steps
- Wash the bottle with warm water and a little soap
- Rinse thoroughly and spray clean water through the mechanism
- Which removes any manufacturing residue from the passages
- Empty and dry before filling with oil
- Fill, then prime with repeated firm squeezes
- Test on a cloth rather than on food
Bottles with a pre-compression mechanism, of the kind catalogued at https://flairosol.us.com/, need a firm full squeeze rather than a light one during priming, since the valve only opens above a threshold.
Why It Needs Priming
The mechanism is full of air when it arrives. Liquid has to be drawn up the dip tube and through the pump chamber before anything can be pressurised.
Until that happens, each squeeze compresses air rather than liquid, which does nothing.
Ten or more squeezes is common on a new bottle, and it is not a sign of a defect.
Do Not Overfill
A bottle filled to the very top leaves no air space, and the mechanism needs some to work properly.
Most have a fill line, and it is there for a reason rather than for appearance.
If Nothing Happens
Check the dip tube is attached and reaching the liquid, which is the commonest issue after transport.
Check the head is threaded on straight and tight.
Try warm water first: if water sprays and oil does not, the oil is too viscous or the bottle is not intended for it.
The First Spray Is Uneven
Expected, until the passages are fully wetted.
Keep the Packaging
Until you have confirmed it works.
Read the Fill Instructions
They differ between designs more than people expect.
Squeeze Fully
A half pull may not reach the pressure threshold, which is why light squeezes appear to do nothing.
Wash Before First Use
Manufacturing residue sits in the passages until it is flushed out.
Test on a Cloth
Rather than discovering the pattern over a pan.
Do Not Force the Head
Cross-threading a sprayer head ruins the seal permanently.
Check the Dip Tube
It arrives detached more often than people expect.
Prime Over a Sink
The first spray is uneven and unpredictable until the passages are fully wetted.
