The cartridge also comes with th brass housing which if youhave a surface valve can make it a little easier to fit

If you have changed to a combi boiler then you will need acombi compatible cartridge and a retro fitting kit

Yes this will require a new cartridge and this will solvethe passing problem.

I think it probably needs a new thermostatic cartridge, however it may be worth stripping the cartridge out and flushing the pipe work out just in case you have a problem with the supply

 First strip out the cartridge

When it is out give the pipe work a flush out.

This will take two!

If your valve is recessed pack an old poly bag round the valve to divert the water into your Bath / shower tray then turn the hot and cold valves on one at a time and allow the water to flush through for about 15>20 seconds.

The person who is helping you should watch that the water is not going anywhere that is going to do any damage also they should watch that the amount of water coming from the hot and cold they should be roughly the same.

If they are roughly the same then you almost certainly need a cartridge if not then you will have to investigate why one has a better flow than the other
