Tap & Shower leaking on bath with dual switch?

[Ngeorge]

Hi I have a bath unit with switch to alternate between shower and bath taps. Recently both shower and taps have started leaking. I believe it's due to the switch but cannot figure out how to dismantle the switch to check.

Please advise how best to take the switch apart?

Thanks in advance.

The taps control the water flow, the switch just diverts it to either the spout or the shower.
So the problem is with one of the taps. If the water is cold, it's the cold tap and vice-versa.
Probably a washer, if they're quarter turn taps then probably the ceramic cartridge.
Simples...

Great - many thanks. Having looked at the taps I can unscrew the base but cant get the base of the tap over the top and so an easy way to get to the inside ?

There's many different ways to disassemble many different taps. Possibly a grub screw is holding the handle part on. Have a good look at it, if you can't figure it out let us know the model of them.

Hi

can't see a model on the tap - bath is Ideal Standards - I've attached picture - as I say I can unscrew the base but can't figure out after that?

Many thanks,Nev.

When you unscrew the base can you see the brass hexagon part of the cartridge at the bottom? If so - you don't need to remove the tap handle part, you can just remove the whole top section, replace washer/cartridge then re-assemble.

After a quick check, these look like the same taps, but with a slightly different selector and different shower head, so if you can't figure it out maybe phone Bristan and ask them how to remove the head of a Bristan 'Axia' tap.

And after another quick look, I think the bottom part should unscrew to reveal a grub screw, as shown here (number 5)

Great thanks.

found the Hexagon screw and unscrewed it - moved it up but the outer casing on the tap blocks me from unscrewing anymore?

Tighten that nut back up.
Read post #8, there is a grub screw you need to undo to release the top part.

Great stuff - will give that a go. Many thanks for your help
