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).
