Mixer tap swivel leaks

[cjcoffin]

I have a monobloc kitchen sink mixer like this https://www.screwfix.com/p/mono-mixer-kitchen-tap-chrome/5497T (except for the finish). It leaks from the swivel joint. How do I get it apart in order to see what is wrong?

Sometimes the collar at the base of the spout unscrews. Sometimes there is a grub screw at the back holding the spout in. Once you get the spout out, there will be a couple of O rings. You are unlikely to find a perfect match but there is a little bodge you can do. Carefully remove the O rings and stretch a couple of turns of PTFE tape in to the grooves. Replace the O rings, smear with silicon grease and reassemble the tap.

Thanks for that. Unfortunately there is no grub screw and no separate collar, the base is one casting and the spout another, seemingly with no visible means of locking the one to the other.

I have a dim memory of a kitchen mixer where the spout would pull straight up when it was rotated to a specific orientation, does this ring any bells? Anything else I can try?

Yes I have come across those but not sure of the angle. Trial and error I guess. By this stage I would be thinking about changing the tap.

I think some just pull out, but don’t quote me if you can’t do that then maybe as per @Elkato531 new tap time

Thanks Elkato531

Answer was just past 9 o'clock. Top tip about the PTFE tape, seems to have fixed the problem.

Yes, tap is well past sell-by date but we had already spent a fun day replacing the service valve (aren't they dreadful) and re-making 4 compression joints on the hot supply.

Also the tap matches the cream sink which itself is discoloured and needs replacing along with 8m of worktop so quite a project in itself. Anyway today's new discovery is a massive moth infestation so all plumbing is on hold!
