Aqualisa mixer replacement cartridge, 600 ?

[Tom]

Hi All,

I thought my Aqualisa mixer was the 600 model (it was here when I moved in in 1993), the parts look similar to the ones on the Aqualisa web site - *but* the cartridge I have taken out doesn't look like the ones offered for replacement.

The original one is white and grey with some brass parts to it - the ones offered as replacements all seem to the plastic. Is this right? I think the part # is 022802 (multipoint (pink)).

Is it that the range of replacement parts doesn't look exactly like the ones coming out because they have gone over to plastic.

Thanks, Tom

Can't remember what model I have - but it's old. A phone call to them got a replacement cartridge which looked rather different but fitted and worked just fine.

Phone their excellent tech support.

As regards the pink/grey you'll have seen from the part diagram/ description (and numbers) on their site, these cartridges come in the options of pink (multipoint) 022802 and grey (thermostatic) 022801. If you have doubts, I'd echo the advice to phone or email their technical support. There are design changes on parts for these old showers. I spent a couple of days looking for an outlet assembly - simple plastic screw and plug - only to find there was a design change which hadn't been fully updated on all sections of their site and where many independent suppliers' sites still showed the old version. Correct current version turned out to be what I'd been show at the first local supplier I'd visited

Thanks for the replies - very quick too - I've contacted AL by email and awaiting their response.

Just a thought, when the shower drips from the shower head ie. water is not getting perfectly turned off, where does the problem lie? Does the whole cart need to be replaced? or could I get away with just replacing seals and rings etc - there is a particularly awkward one that is seated at the connecting end of the cartridge shaft where the cartridge connects/goes into the plastic shower body to form a moveable seal ...

Just wondered. Any advice would be welcome on this.

I just wondered if anyone knew if the cartridges could be swapped between the 409 (yes its a manual mixer) model and 600 (thermostatic)

- I have a 409 manual mixer that isn't needed...

Thanks, Tom

Diagram for 600 shows a different body/number for the manual version (and a different temp control lever - though thermo lever might screw to a manual cartridge). But isn't one of the thermo advantages that all that bimetallic thermo coil adjusts, as water supply/temperature to hot or cold varies, and I think it shuts off quickly to prevent scalding if cold water is substantially interrupted.

manual cartridge might depend on how variable supply pressure/ temperature is likely to be when other taps devices in house are in use.

I spent ages finding the correct O rings to cure my AL dripping. Didn't work. ;-)

Hi All

Thanks for the replies, particularly Toom for all the help given.

After contacting AL with a photo of the old part they confirmed that part # is 022802 (multipoint, pink) for this Gothic AL mixer (600). The parts have changed a great deal since mine was manufactured, hence the confusion. Got the replacement cart yesterday, the fitting instructions were brilliant - some of the new screws *cannot/should not* be used as the old design requires the original screws (mixer body for this old model has brass screw threads so the self tappers into plastic would spell disaster if used).

nb this cart # comes with different restrictor filters for the hot inlet (end of the cart shaft) for different boiler BTU outputs - not sure of the consequences of getting it wrong but this needs care selecting the right one.

Fitting the hot water inlet O ring was tricky (back of the plastic mixer housing), or I should say removing the old one was - the only way I could get this out was by very carefully poking it with a long sewing needle (AL recommends a croquet hook, but this was too blunt to get the old ring out)- care needs to be taken not to damage the housing recess in which the O ring lives - putting in the replacement was a doddle!

So far so good - no leaks, touch wood - and it works like a dream,

Thanks again Toom,

Rgds., Tom
