This question is regarding Bristan Pisa Thermostatic Surface Mounted With Adjustable Riser - Shower Spares

Bristan Pisa Stiff

My Bristan Pisa has a very stiff on/off control which has gradually got worse. I am now having temperature issues where by the water is cold however the pipe to the left hand side is hot.



Looking at the other questions I assume a new Thermo Cartridge is the answer however before I purchase one is it worth taking the old one out first and giving it a clean etc to see if that helps?



If not can you tell how long a new cartridge should last? If this older model is plagued by the same issues is it worth just replacing it altogether.



Thanks

Taking it out and greasing the seals should make it move more easily, however I don’t think it will have any effect on the temperature, however it is probably worth a try.

I think you are going to need a new cartridge.

 

I would say that 10>12 years is the average life of a cartridge however it  can be a long way either side of 10>12 years
