Sirius 1850 shower

You identified my shower in earlier email. You suggested new cartridge. The water temp has been cool for several wks and control stiff when turned towards the cold. Would this suggest it also needs new thermostat?

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.

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.
