SMR Valve 1212R 3819R



SMR Valve 1212R / 3819R .

But please read all the information below before ordering.

If your Tap is dripping from the Spout then you might need to change your Valves.  Here is our Guide 7 Easy Steps to replace Kitchen Tap Valve. Please read below before ordering as there is additional information on this Valve.


SMR Valve 1212R / 3819R – WHAT VALVE TO ORDER?

  1. San Marco 1212R

    This Valve was originally produced with a White Seal and had ‘San Marco & Date or Code’ stamped on it. If your own Valve is stamped ‘San Marco + date’, and white seal underneath, then please order 1212R + white cold or hot here £16.   Please note though that some of these earlier valves have been discontinued and we cannot guarantee an exact fit for much older taps due to the difference in the nut height between older discontinued valves and the current San Marco 1212R Valve that is available. e.g. Old Tap with valve stamped San Marco B01 , for example, for the Rangemaster Tap TRS1: We have found that due to a different height nut in the current 1212R Valve, there is in some models of this Tap a slight gap between the Handle and the Body. If you have one of these taps and fit our valve, you cannot return it once fitted because of a handle gap as we have flagged it in advance to you here. We do not accept returns back where a Valve has been fitted and we have flagged a potential issue due to it being a discontinued valve. If we don’t flag an issue then that is different.

  2. SMR 1212R aka SMR 3984R.

    In later years the 1212R has been produced with a coloured seal (Blue / Red) and is stamped ‘SMR & Date’. This can be referred to in Installation Guides as either 1212R or 3984R If you don’t have an installation guide but your own valve has ‘SMR + Date’ stamped on it and blue / red seal, then order same here, 

    Whatever Valve is in your own  Averon or Emporia Tap (i.e. 1212R OR 3918R, you will need to order the ‘San Marco  1212R with White seal’ as a replacement.


  3. SMR 3819R


    Later again, Taps now have the one threaded version of this valve, called 3819R, and stamped ‘SMR & Date’ .  This is for Taps where the second thread is not required.  (The second thread is usually used to hold a Valve Cover in place).  The 1212R stamped SMR with blue / red seal is interchangeable in most taps with the 3819R valve i.e. you can substitute the 3819R withthe 1212R BUT you cannot necessarily substitute the 1212R for the 3819R as some taps have a valve cover that requires a second thread.

  4. 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.

POST COST: For very small items: Screws, O Ring Kits, Aerators & some Bushes, we Post (£2/£3.50). This is NOT trackable.     Where we Post, and you have been incorrectly charged Courier Rate £5/£7, we will refund the excess shipping charge to you. Some Parts cannot be posted e.g. Valves.


ROI / NI: Approx 2 days delivery by Post.

Great Britain: Unfortunately there is no such thing as first / second class mail in Ireland. There is just 'standard' post. Our current experience is that it is taking approx 1-2 weeks for goods to arrive in Great Britain by Post. But we are having reports of it taking even longer than this. This is outside of our control and the backlog appears to be due to customs clearance for all items creating a backlog, slowing down all inward parcels and post from EU.

COURIER DELIVERY TIMES Track & Trace (£5/£7) & we make no profit from these charges):

ROI / NI: Approx 2 days delivery by Fastways.

Great Britain: Average shipping time with DPD is approx 1 week (but can take longer) .

Please note that delivery times with DPD UK for goods shipped from Ireland are slower than DPD within Great Britain. Brexit means that all goods coming into Great Britain have to clear Customs and this has added delays to the process. Our current experience is that goods shipped with DPD UK currently take approx 1 week to be delivered, but it can occasionally take longer. We can provide tracking numbers if required.
