New cartridge and washer

[psarinuk]

Hi,

I've a mixer tap that is dripping from the hot water side.

I've removed the cartridge and there is a rubber washer at the bottom. It seems to be 3/4 inch with a hole in the middle. When measured, its 17mm diameter to be precise and its not coming off. I've already damaged it slightly while trying to take it off. It seems to be half-embedded into a metal casing.

Can someone please advise if I can get a 17mm washer or if a replacement cartridge is available.

Many thanks in advance..

Should be able to find a washer for that without a problem. Take it along to a local independant plumber's merchant, they'll be able to sort you a washer of the correct size. Most have a box full of assorted washers tucked away somewhere, they're usually happy to sell one or two, and may even fit it while you wait!

Can't tell from your badly out of focus picture, but is that a hexagonal nut holding the washer in place?

If so, have you tried to remove that first?

Hi Charnwood,

Yes its a hexagonal nut but I never thought it would come out or hold the washer as it did not seem that way looking at it. I will need a vice to hold this if I am to try and remove this nut.

I am attaching another pic for your reference.

This is the bit I mean. It does not look hexagonal to me:

Anyway, that's what is holding the washer on.

washer looks ok, i'd check the seat before going any further.

Hi, Do you mean seat of washer in the cartridge or the metal seat of the main tap body?

Sometimes these brass ends unscrew, sometimes they don't......either way a new washer should pass over the end (helped by some wash up liquid) and then you can test the tap.
Before you reassemble, see if you can see the 'land' inside the tap body where the washer locates to.....if its badly scored then it could be reseated, if its cracked then its new tap time.

.if its badly scored then it could be reseated

Could you please advise on how to reseat?

Screwfix 57400 is a tap reseating tool....they work reasonably well.
