When the shower runs it stops after around a minute. do you think this could be the thermostatic cartridge, if so how much are they
Asked 12 years ago by Anonymous

First remove thethermostatic cartridge and make sure that the filters are clean and clear

 

 

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

 

 

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

 

Watch that the water is not going anywhere that is goingto do any damage also you should watch that the amount of water coming from thehot and cold they should be roughly the same.

 

If you still have a problem with the water cutting offthen you almost certainly need a new cartridge.

 

There two cartridges if you don’t know which one you havetake a photo of it when it is out so we can ID it if you need a new cartridge.
