This question is regarding Bristan CART5 Dual Control Thermostatic Cartridge - 06732COMPL

Cartridge getting cooler after a few months

Hi



I bought a new cartridge off you recently and it worked fine for a couple of months. However, its now a few months old and it seems to not reach the high temperatures as well as it was. I have re-installed and selected the highest temperature possible but it makes no difference. It is able to provide cold water, just not as hot as it should.



Any suggestions? I have considered that it might be that the thermostat has a build up of limescale affecting it, and wondered if it would be worth using a mild kettle descaler on it. However, I was worried this might ruin it. Any thoughts?



Thanks

If you have a limescale area then,

The first things to check are:

1  That the main valve coming into your house is fully open.

2  Then check that the valve on the line to the shower is fully open.

If these valves are not fully open then there may not be enough water getting to your shower.

If there is enough flow then it could well be the thermostat and you idea may well help.
