Aqualisa old unit

I think it's green ring for an Unvented.

You had better identify the model number of yours because I think older mixers do not fit the same cartridge.

Their Parts dept seem quite helpful, though.

There £125. It might be just as easy to put a new shower in ‍

Cheers guys. Great answers & some food for thought

post back when you know. I may have a NOS Aqualisa round-knob mixer on the shelf for half price.

When you have an unvented Cylinder installed , the cold for your shower needs to come from the balanced cold feed at the control group on the UHWC, if this hasnt been done that could be your problem

Cartridge removed dont look good to see what u guys think?

 

[Owen11]

Ive got an unvetted system now shall i get this?

 

[JohnD]

Well it's thermostatic, black ring, and looks clogged with rusty scale. Are you in a hard water area? I don't know where so much rust came from.

If you have a pack of kettle descaler you could soak it overnight but really you need new.

I'll look on my shelf tomorrow.

But now i have a unvetted system will i need the green one? Because before it was a gravity feed system.

Well that's definitely seen better days. Get the grey one, they're universal now
