This question is regarding Trevi 1/2"" DX 1/4 Turn Flow Cartridge, Anti Clockwise Close

Trevi A3000AA shower - No cold water and unable to turn shower off fully, still dripping

I have read a few of the questions that have a similar issue to myself but just wanted to double check the parts I need to try and fix the issue. It seems that I need 2 1/2"" Dx 1/4 Turn Flow Cartridge Anti Clockwise Close to solve the problem. Just want to confirm that one needs to be fitted on the knob that turns the shower off and on and the other fitting on the knob that controls the water temperature. Is this correct as other answers say you need to replace 2 at the same time.

Yes you are best to bit a pair of 1/4 turn cartridges They both fit in the gearbox behind the on/off knob

When fitting make sure that both cartridges are both fully open or fully closed.

Regarding the dripping problem this maybe caused by faulty flow cartridges which will need replaced.It is better to replace the hot and the cold , www.showerdoc.com/shower-spares/trevi/IDL-A952501NU11-Trevi-1-2-Inch---Ceramic-Flow-Cartridge-A952501NU11 If the new flow cartridges don’t solve the problem then it is just possible that you will have to replace the gears and clutches.
