This question is regarding Bristan Sonique Sequential Thermostatic Shower And Riser Kit - Chrome - Shower Spares

Temperature pulses hot and cold

Hello! i have a Bristan Sonique, and ever since it has been installed the temperature seems to have cold pulses... - the hotter the shower is the worse it gets, but as a rule for every couple of seconds of hot water it gives a blast of cold! Most unpleasant! I assume it is some kind of thermostat cut out issue, is this something I can fix?



Many thanks

Regarding the temperature fluctuation or cool running it could be a faulty cartridge however to check this, 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.
