This question is regarding Bristan Ceramic Disc Valve - VLV 04070TER-OF

Bristan shower

The shower is running and shutting off fine, but only running cold water no matter what setting it is at.

Would just replacing the ceramic disc help or should i replace the full cartridge? The full cartridge was only renewed 3 years ago.

Regarding the cool running, it could be a faulty cartridge. However to check this if you have the shower fed from a combi boiler, see if you can get hold of the hot supply pipe before it enters the shower or perhaps as it leaves the boiler.


If when holding this pipe the temperature fluctuates or goes cool, then the problem is not with the shower but more likely with the boiler, as the shower can only deliver what the boiler sends to it. 

Disregard the temperature at the taps as they have a different flow rate.

Changing the CD will not solve the problem.

OK thanks Barrie, our hot water is supplied from our mains megaflow tank, we have 2 showers which run from the same water flow, and the other one is working fine. I guess I will have to order a new cartridge again, can't believe it has only lasted 3 years from we last changed it.
