I have a problem with an Artisan thermostatic bar shower (type AR SHXMTFF C).
The initial problem was that the shower only ran luke warm even on the hottest setting. I changed the thermostatic cartridge but now it’s stone cold with the temperature control turned to 15, then red hot from 30 onwards with no control of temperature in between.
The shower has been working fine for 2 years, the hot & cold supplies are from a conventional system (cold water tank in loft & hot water cylinder in AC) it’s fed from a 3 bar pump (another shower off the same pump works fine). The hot and cold are the right way around, the NRV are ok and the filters aren’t blocked.
One thing, the new thermostatic cartridge I fitted was a plastic type, the original was brass, they physically look identical but could this be the problem?
