Trevi shower mixer

It's got very stiff to turn on, then it's on runs for a minute and then the water stops coming through

Being stiff to turn on may mean that you need to replace the on/off cartridges

You will need two, you may also have to replace the gears.

The water stopping could be a faulty temperature cartridge, however the first thing to do is to strip the cartridge out and make sure that the filters are clean, if the valve happens to be on a pump check that the inlet filters on the pump are clean.
