Aqualisa 900 concealed shower valve leaking?

[Mutley56]

Good afternoon,

There is a small but constant drip from under the temperature control lever on my Aqualisa 900 (I think) concealed thermostatic shower valve. It is a metal body one and only drips when the shower is on.

Do you think the whole cartridge needs replacing or could it be that fiddly O ring at the back of the valve that needs replacing?

Thanks in advance.

1. It could be a number of things, including the screws which hold the cartridge cover in place or the cartridge gasket.
2. Replacing the fiddly O ring is probably worth doing as a first step.
3. Take the front off and see if that reveals where the leak is coming from.
