Bristan Pisa - New Cartridge still problems

Hi,



I purchased and fitted a new thermo cartridge to my Bristan Pisa shower and all was well for 6 weeks.



At the weekend the water was ice cold again and the hot water feed elbow was cold. I removed and replaced the cartidge and all seemed to be well again - hot shower and feed arm was very hot - until today! shower is ice cold again as is feed arm.



Can you diagnose my problem? The cartridge is brand new and all seals are well greased so all looks fine from that point of view.



The rest of the shower is approx 10 years old however I am afraid that if I replace the entire shower I will still have the same issues.

HiAndy

Ifthe elbow going into the shower is cold then that would suggest a fault withthe boiler, the shower can only deliver what the boiler sends to it.

Iunderstand that the other taps may be OK however they will have a differentflow rate compared to the shower, perhaps it would be worthwhile gettingsomeone to look at the boiler.

Ifyou get hot water at the shower inlet and the shower is not working properly thenyou could have a faulty cartridge.
