For the following Taps, we recommend replacing with the 1212R White seal : Averon, Emporia, Bristan Beeline, CDA TC55, CDA TC56 and CDA TF55 The 1212R valve with white seal looks a little different as it has two threads whereas the 3819R has one set of threads. It is the same height etc and the most important feature of this 1212R Valve is the larger white seal. If you replace your valve with a 3819R and your own Tap is one of the above listed, there is every possibility that your Tap will continue to drip. The 1212R White sealed valve should not drip , if it is a valve reason that is causing your drip to begin with. This link here will bring you to the 1212R Valve with White seal. ' as a replacement. If you are unsure, then just email us a picture of your own Tap and a picture of your own Valve and we will advise you before you place your order.


If you remove your valve and the diameter is wider than expected, (see Gallery images) this is because the bush is stuck to your valve. There are two types of bushes that are very similar in appearance, the 3408R 36mm diameter and the 3409R 30mm diameter. We recommend that you take measurements before you order if your own valve looks similar to the images here below and in the gallery as its not always possible for us to accurately assess which Bush you have based on pictures as the mm differences are small, but the correct sized bush must be ordered as a replacement to fit your own Tap.
