SMR is stamped on valve

SMR is stamped on valve

and usually a date stamp e.g 01/2013 although some earlier models used number codes as well (Please note that earlier Valves have San Marco stamped on them but whether SMR or San Marco, the same valves apply).
These numbers / dates is not sufficient to identify which SMR valve you have.

If you send in a picture of your TAP we might recongise and identify WHICH San Marco / SMR valve you have, but the more information you can send at the same time, the quicker it is for us to identify which Spare Tap Part you need.


If not, then we would need to see pictures of the Valve itself plus the measurement of the Valve from Top to  Bottom (Brass).  Note: please ensure that you try and take as accurate a measurement as possible. We frequently get pictures of the valve beside a measuring tape but this means that we are still trying to guess the height.

See below for the most common SMR valves that you can check your own valve against once you have removed your own valve and taken the measurements.


Usually your Kitchen Tap is dripping from either (1) the spout or (2) where the spout meets the base.

If it is dripping from the Spout then it is most likely that you need to change the valves (one or both) and / or the brass bush ring (but usually its just the valve) hot or cold.

If your tap is dripping where the spout meets the base then it is likely that you need to replace the O Rings (see below for O Rings).

We stock all San Marco Valves (unless the Valve has been discontinued).

In order to identify which San Marco Valve you have that needs replacing we will need you to EMAIL the following to us:
1. 4 measurements
2. Picture of your Kitchen Tap showing full tap i.e. spout, body etc

Here are the 4 most common measurements :

San Marco Valve Blueprint
San Marco Valve Blueprint
  • Length of Valve from top to bottom (brass) in mm
  • Diameter at thread: in mm
  • Number of splines – always an even number, e.g. 20, 28…
  • Nut (below splines) Height: in mm

Here is our Guide to assist you in removing your valve: 7 easy steps to replace kitchen tap valve
Please make sure that when you have removed your valve, that the brass bush wasn’t removed as well (this surrounds the valve inside the tap) and you will need this for the new valve. If you find it impossible to separate the two we do supply brass bushes as well for San Marco Valves. For more information on removing the brass bush, see here.

The picture of your tap will help us identify which O Rings you require.

Don’t forget to also email us a picture of your Tap. Email all details to

How to tell a Hot Valve from a Cold Valve – Some Valves have blue or red indictator underneath to distinguish hot from cold, but if both valves have a white indicator underneath:
Example of a San Marco Hot Quarter Turn ValveIts very simple to distinguish between the Hot and the Cold San Marco 1/4 turn valves:


The Hot Valve has a nick on every side of the nut whereas the Cold valve doesn’t.

    I am looking for a replacement cold water valve cartridge for my mixer tap. The dimensions are: Height 5.5cm, thread 2cm,nut height 1cm. The date stamp on it is SMR 01/15. I have a photo of the valve and tap but can you advise how I send it to you.

      Hi Neil can you email us a picture please if you havent done so to determine which valve it is that you have. Also a picture of your tap as well please as there are certain taps that the manufacturer recommends the two threaded version of the valve as a replacement, even if the original valve in your tap is a one threaded. Until we see the tap as well we won’t be able to recommend the most appropriate valve as a replacement for you

    Hi i am looking to replace a tap gland “SMR 01/12” i was just wondering if you are able to determine the diameter from this?

    • Alice November 2, 2019

      HI Gordon, as outlined in the post, that is just a date stamp. We would need details of your own Tap (pictures) and Valve (pictures). Sometimes we also require measurements, but usually pictures are sufficient and if you have removed the valve to see date, then you can take pictures of the part at the same time. Please email to . If you have put back the part, email your Tap picture. We still might be able to advise you based on this. Alice

    Hot tap is dripping. Ceramic is marked SMR 06/11. Please advise corresponding Part no.
    Thanks for your help. R&R

    • Alice November 8, 2017

      Hi there, if you read the blog that you have posted in underneath , you will see that 06/11 is only a date stamp. As per the blog at a miniumum we need a picture of your own Tap and a picture of your own Valve to identify WHICH SMR Valve you have.

    My cartridge has SMR 10/13 which one do I need ?? cheers

    • Alice May 21, 2017

      Dear Peter – as per the blog post above that you posted your comment on, that is just a date stamp on your SMR (San Marco) Valve. We would need you to send in the information e.g. Pictures as requested / detailed on the blog and basic valve information for us to identify WHICH SMR (San Marco) Valve you have in your tap. You can start by emailing a picture of your Tap AND a picture of your Valve , but to save you going back and forth, measuring the valve height from top to bottom of brass would also be useful. Alice

    My mythos tap is leaking on the cold side. The valve is stamped smr01/12.
    Can you please tell me what to order to replace the valve.
    Best regards
    Colin crease

    • Alice January 13, 2017

      Dear Colin, here is the link to the Mythos Valve. If you click on this link here it will take you into the Valve to purchase it. You need to order the Cold Valve for £14 and you will receive an SMR valve. 02/12 is just the date of your SMR valve. Please ensure that you read all the additonal information on the brass bush which costs £10. Thre brass bush is cylindrical and sometimes when you remove your valve, this comes out as well. If your valve and brass bush cannot be separated then you will need to order a valve and a brass bush. The same Brass Bush is used on both the hot and the cold side (one brass bush per valve). If you are ordering the parts and waiting on a plumber to remove, then you might be advised to order the brass bush as well as valve and return to us within 28 days for a full refund excluding shipping charges if it is not required. That way you will have all the parts that potentially might be needed when the plumber comes. If you are doing it yourself there is a guide on the valve link 7 easy steps to replace kitchen valve that should assist you and then you can check your own valve (and whether you might need a brass bush) prior to ordering. Our shipping and returns details are on the product details.

    I can’t find original paper work for my two Franke taps which means can’t identify which tap it is! We installed the kitchen 10 years ago and think its a one tap mixer tap

    • Alice December 9, 2016

      HI Cliff. I emailed you. For ease of reference, if you don’t know which Franke Tap you have, here is the Franke Spare Parts section which shows every Tap by image for spare parts that you might be able to identify quickly yourself, and then the Valve specific to that tap will have a link to the Brass Bush (should you require it).
      If you are still unsure, or you can’t find your Tap listed, then you can email us here with the following:
      1) Picture of your kitchen tap. Please make sure to send a picture (or pictures) of your complete tap in such a way that we can identify it. Sometimes we receive pictures taken at angles or in poor lighting that make it impossible to identify the tap. Difference between some taps can be subtle but It can make all the difference when it comes to identify the correct spare part !
      2) Any information that you know regarding the age of your tap – e.g. installation date ,
      FRANKE FILTER TAPS (Triflow or Filter flow)
      If you have a filter tap then please read this post.
      It will help you identify the correct tap as some of the Triflow taps and Filter flow Taps are very similar but have completely different parts.
      This Franke Tap Spare Parts Guide Section here contains many blog posts to fix the most common Franke tap enquiries that we receive and might be very useful as well as your own tap could be listed there with the answer for you.
