Shower temperature

Hi, my shower keeps going from hot for 3 minutes then stone cold for a minute and so on. I fitted a new thermostat and this has made no difference. Any ideas? Many Thanks Rich

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.
