Thank you. Did you see my problem?
I hoped to be able to stop the drip by getting new seals but I don't see how to fit them.
I've taken the cartridge out but I think that I need to dismantle it further.
Yes, removed those.
So it seems! There are two more screws after undoing those 4 and I've removed those also.
Sorry - got a vital phone call. Back with you.
Yes it looks like that only grey. (No pink)
Yes, catride out and here on a tray.
Is that in the space that the cartridge came out of?
I'll check (another room)
(I have a photo of the cartridge - should I try nto send it?
I got a set of rings. None is called an O ring but one of them may be.
The ones I have have numbers
Probably the serial numbers are the ones that I sent with my original message.
I have the Aqualisa cartride internal seal set
The one labelled 05 looks about thr right size and there are two of them in the set.
They're all black rummer, 2 larger about 8mm diam.
Thank you. I suppose I just need to fiddle now and if the ring that I get out is a different size from the new ones that I have I'll have to take it to a good plumber to see if they have the right one. But I suppose that the set I have may include the correct one even though it seems to be for a different cartrdidge as there are more rings that I need.
Thank you. I'll set to work.
I did change the ring. I made a little tool by heating the tip of a long needle in a gas flame so that I could bend it into a hook. Unfortunately it didn't improve the drip so I got in touch with Aqualisa who were also extremely helpful. They thought that it was unlikely that changing the ring would help and advized changing the core, either myself (cheaper) or have it fitted with a 2 year guarantee. As I'd already spent ages on it and fearing that I might still have problems I've gone for the expensive option and console myself that I've tried my best.
Incidentally, this rarely used mixer is 20 years old and the other that we use at least daily and which looks just the same has given no trouble for 30 years.
Thank you again for your help.
