This question is regarding Sirrus 1850/968 Thermostatic Cartridge without Thermostat - SK1850-2

Sjower too hot

I have a Bristan Tulsa SHower but the temperature is too hot and cannot be lowered. Do I need a new SK1850-2?

With the Sirrus 1800 series that in almost every occasion the first thing to do is give them a strip down clean and lube and fit a service kit, this will cure 85% of any problems and it is also the cheapest thing to do.

If after servicing you find out that it needs a thermostat or piston, nothing is really lost because it almost certainly needed a service in any case



The 1800

There is no real difficulty with this valve however it is a little more complicated than the 1500 just take photos as you strip it down you can then refer to them when you are rebuilding.
