    Hi,

    Does anyone know how to dismantle the bath mixer tap below? The problem is if i send the water to the shower i get a lot of the water still dripping from the main tap into the bath. I have tried opening from the top nut (just above the "ball") which removes the shower head holder but cant see anything inside to remove, and I have also tried removing the lever but I cant pull it out. I'm obviously doing something wrong. Is there a way to fix this?


    Thanks

    I would imagine there is a screw under a cover in the end of the lever you may need to prise it out or it might unscrew, then the diverter will be held in with a circlip or screwed into the body.
    If it is coated in scale soak it in vinegar

    Thanks footprint.

    So I removed the cover in the end of the lever by unscrewing the cap and all I can see is a hole. There isn't any circlip or screw which holds the lever to place. I have tried pulling it out but to no avail.

    I also removed the top but i still cant get through to the inside.

    Here are some some pictures:

    any suggestions?

    I wonder if the shroud (bell shaped chrome cover) would now unscrew after the arm has now been removed. It will no doubt have scale holding it but try gripping it firmly with something like a rubber glove and unscrewing it, that might reveal a large nut underneath.

    If its like the Bristan type, that chrome bezel that the handle screwed into is held on by a central screw. If it won't come off with the screw out, then its seized in place with limescale.
    If you can shift it, there's a disc with a peg within that turns the diverter.

    Give it a good soak in vinegar or decaler and then give it a good old waggle back and forth!

    Thank you both.

    Now that I know the chrome cover is a cover I'll give it a good twist a pull later when I get home.

    Would WD40 help?

    WD 40 can't do any harm and usually helps to loosen up corroded and seized things, but I would try decaler first, being brass it's not going to have any corrosion on it. Also worth pouring very hot water over the shroud to try and expand it a bit.
