Mira shower mixer help needed plse

[olly_k]

Hi folks, my mums shower mixer has become a sod to use - basically the outer flow dial has pretty much seized making the shower difficult to turn on or off.
It is externally in good nick so is it worth trying to strip and clean / replace seals etc or are we better off buying a new mixer unit?
It may sound like penny pinching but I would rather not disturb the tiled wall as it is studded you see.
Oh, I would guess it is about 20 odd years old?

Thanks

Olly.

A 20 year old Mira is well worth lokking into for a service kit. if its an 88 its a dodle, ifts a 722 Or 723 then its a thermastic. bit more involved & the bi-metallic coil may be coroded . Is the re a model no on it or has it a centre knob that turns left to right, is it built in or exposed. Service kits are about £17 -£20+ .well worth ago . normally as good as new after,

Thanks Bab I didn't see a model, I have piccy on my phone but left that somewhere will post tomorrow.
The black outer dial controls water flow and inner white dial temperature - I am pretty sure it is not thermostatic caus it did suffer fluctuations in temperature but I can't be sure. It is surface mounted with two 90 bends into the 'barrel' as well.
Oh, when I take the white dial off the black is held by a circlip and on removal of that I think there was a largish nut? Didn't go any further as cold is fed from a tank which will need either bunging or emptying.

I have most of the service manuals if you find the model, ( on the front plate)

From memory its a Mark 1 88 . very good old piece of kit. Buy a srevice kit for it & it will come with an exploded diagram of the valve. With the water isolated undo the large nut. if u can get that loose every thing else is a dodle.

Hi Bab, I have a photo of the shower here if you could confirm please.

Should I just ask for a Mira ### service kit?

That looks like a Mira 88.

 

[doitall]

Looks like an 88 to me as well

Looks like an 88 made in around 66.

did you know you could get the temp knobs with the H+C indices reversed to enable it to fit where the feeds are existing and couldn`t be swopped ........bloody good service from Mira..that small thing years ago led me to stay with them and recommend them

Clever idea... but I just turned mine upside down so the left & right were reversed

 

[doitall]

1988 actually

 

[bab]

Yeah mark 1 88 The earlier model was the Mira 8 with a grey centre knob. I think its the same service kit on the mark 2 88 as well so its a good cert,any way.

 

[Softus]

Oops! Quite right - Mira 8 it was, and grey knob it was.

Like the man in the orthopaedic shoes....
