Which Tap Do You Have?
A) Standard Aerator
You will notice at the end of the faucet there will be a small piece that is able to be screwed on / off.
Go to Step 2
C) No Aerator
You will notice an open end on your tap with no aerator or thread visible.
Go to Step 3D) Retractable / Veggie Sprayer Tap
Due to the design of the retractable or veggie sprayer tap, a bench top filter is unable to be attached correctly. You may want to consider installing an under sink filter.
View Under Sink SystemsSTEP 2 — IDENTIFY YOUR TAP THREAD
Once your aerator has been removed you need to determine the thread type.
A) Internal / Female Thread
The thread is on the inside of the tap.
This will need a male adaptor.
B) External / Male Thread
The thread is exposed and is on the outside of the tap.
This will need a female adaptor.
STEP 3 — IDENTIFY THE ADAPTOR SIZE YOU NEED
In this step you need to measure the diameter of your aerator or the end of your tap in millimetres (mm) to match the size of the tap adaptor in the next step.
Internal / Female Thread
After you have removed the aerator, use a ruler to measure the diameter (mm) of your aerator for an internal / female thread.
External / Male Thread
Use a ruler to measure the diameter (mm) of the end of your tap for external / male thread.
No Aerator
Using a ruler, measure the diameter (mm) of the end of your tap opening.
