The easiest way to determine which valve is in your own tap is to remove the handle and count the splines (ridges). If not sure when you have removed the handle, you can always email us a picture of valve in situ (handle off) and we can tell you which valve is in your own tap .
There is a screw where the black band is to remove the handle. Here is our guide to remove your tap handle.

If your own valve looks different when you remove it, assuming that you have correctly identified the Tap, then it is most likely because the brass bush is still attached.
If you are not sure which Valve you have in your tap , just remove your handle and count the splines (20 splines for Pre January 2013 and 28 Splines for Post January 2013). Here below is an Example (different tap but shows what the 3547R valve looks like in a Tap with the handle off).

We ship from Ireland. DPD have notified us that they are experiencing shipping delays in GB due to Brexit (Customs). They currently advise us that these delays are temporary. However, as per the Large Popup notice on our website that is there until you Dismiss it, you should allow a minimum of 1-2 weeks delays for your order to be cleared by customs. This backlog is due to the volume of goods now going to /from GB that have to go through Customs from January 1, 2021 due to Brexit. It is outside of our control. (There will be no extra or hidden charges with your order). For very small items such as grub screws and O Ring Kits, we will post (again allow some delays) and refund the excess shipping charge .
We intend that Brexit will have no financial impact on our customers.
For further details please see our Brexit section here.
