Franke Mythos MTV MTX MTV Tap Valve

Earlier Installation guides list 2552R Valve. Then in subsequent ones it is referred to as 1427R (SP1427) and even later ones again 3561R (SP3561)- This are all the same valves. We supply the original version of this with the white seal underneath as it is largest seal available for your Tap and the older the Tap is, the more important it is to fit the largest seal possible as it mitigates against any possible Tap modifications made over the years to your Tap that a later Valve might not address in an Earlier Tap Model. This valve will come with a white seal underneath and is known as the 4276R. It is sourced from your Tap manufacturer and is recommended by them to use in older Taps. If your own Tap installation guide specifies a later valve, 3547R (SP3547) then you can order that. Where you do not know the age of your Tap, then you could order the 4276R. We cannot take responsibility for a dripping Tap after you fit a new Valve, if it transpires that you had the the earlier valve 2552R / 1427R and ordered the later one 3547R. We have provided here measurements and images of both valves for reference if you don't have your installation guide.  Please also see below regarding the Brass Bush Part as it might be relevant also . Here is our Guide How to remove the Handle on your Kitchen Tap. if you wish to remove your handle and email us some pictures. Here is our Guide 7 easy steps to replace kitchen tap valve.

Useful Tip

If your valve seems wider in diameter than the replacement valve you order, it is possible that the Brass Bush (Ring) that surrounds the valve inside your Tap has also come away with your Valve.

Should you also require a Brass Bush (one per valve), the same part number SP3886 is used on both Hot and Cold Valve.

Parts might be modified by the manufacturers as part of their continual improvements. We cannot always guarantee that a part will fit an older version of a product. All spare parts that do not fit can be returned for a refund excluding shipping costs.

We ship from IRELAND so please see below for SHIPPING TIMES (by Post or Courier) before you place your Order to avoid any misunderstandings regarding estimated arrival date for your order once dispatched.

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. Click here for more detailed information about all Shipping & Returns.

Not shipping to UK Offshore Islands:

We are currently only shipping to England, Scotland, Wales, NI and ROI. We are currently unable for logistical & customs reasons to ship to Channel Islands, Isle of Man or any Isles off mainland GB. All we can suggest is that you might be able to have the Order shipped to GB and from the there get it shipped on to your own address if it is one of the destinations that we currently do not ship to.

BREXIT: Brexit will have no financial impact on our GB customers once your Order is less than £135.

There will be No Vat on Imports, No Customs Charges, No extra or hidden charges once your Total Order is less than £135.  We will remind you again about this at the Checkout stage before you complete (pay) for your Order.  For further details please see our Brexit section here.
