Be aware there are fake Chinese copies of this system sold and strangely they charge more for them, we only sell the genuine DOULTON units. How can you tell the fake from the genuine, if you look at the photo of the base of the unit you will notice the Doulton name and address stamped into the base, the fakes don't have the stamp.

A standard sized aerator is 13/16th (22mm) if the thread on the spout is male or using the supplied adapter if the thread in the spout is female and is 15/16th (24mm) diameter.
