Here is a link for you.
There is an acrobat reader file, name "parts" below, download it so you
will get an idea, of what a "Thermostatic Cartridge" looks like, that
you will have to replace, don't let the diagrams intimidate you because
if you print a copy and remember the sequence you remove each part by
numbering it on your printed copy.

What you will have to do is to find the correct model that you need on
their Web site or phone them for help.

Well it sounds like you have a thermostat valve, most of the time when
they need replacing is generally when they leak and cause constant
dripping, is yours wall mounted or the bedded type that is on your
bath, they tend to have a filter where they connect to the water under
the bath but I would recommend a plumber to deal with that, if it is
the valve itself that is gone generally they drip and quite expensive
to replace, you have got to know the name of the mixer to obtain the
new valve there is loads of different makes, some of them are easy to
replace but some of them are a mission.


I looked a little closer and see that it is a Moen. They must not be
proud of it, though, because the lettering is very tiny.
