    Hi,

    Looking for a bit of help and advice please in relation to tap valve sizes.

    Mixer bath tap valves have been playing up so decided to replace them.
    I purchased this from screwfix:-

    https://www.screwfix.com/p/swirl-contract-bath-tap-reviver-kit/19163

    However when I removed the tap valves I was faced with the following problem.
    The hole is to large for a 1/2 tap valve.
    The hole is too small for the 3/4 adapter, that comes with the kit, which allows you to fit 1/2 valves.
    Previous occupier has fitted some sort of reducer to one of the holes which allows a 1/2 tap valve to be used, however this has created a greater distance between the rubber washer and valve seat which means when you close the tap the internals of the tap unscrew themselves and you can't then open the tap.

    There is no manufacturer marks on the tap.

    Would I be better off just replacing the whole tap? and do modern taps come with a standard 1/2 or 3/4 valves to save any future issues.

    Thanks for any help and advice offered.

    I would just replace the whole tap. Also modern baaic taps generally only use 1/2 and 3/4 but alot will only use 1/2 cartridges even on their bath taps.

    It is mainly 3/4" for bath taps & 1/2" for sink taps. But if you have an old Armitage shanks tap then that's a different kettle of fish and & you will have to source an Armitage Shanks tap insert from your local plumbers merchant.

    There should be some brass disks and longer screws in your tap reviver kit, use them to extend the washer so the works can't unscrew as you mention above.
    If that fails you can try The Tap Magician
