Evening guys/gals, My Triton shower after only a few days after installation has become really temperament, and the differenct between scalding hot and lukewarm is half a hairs breadth movement on the dial. Does anyone know what's wrong? The shower that was previously there had the same issue and ultimately started to send out boiling drips of water/steam which is what lead to replacement. It's getting power fine, the water pressure is good to the house and there's nothing else using the water when the shower is in use. The first few days after installation were some of the happiest of my life, where the pressure was great and the you could choose whatever temperature suited the mood. It all went down from there really! Can I really have just had two showers that suffered the same fate in such a small space of time or is the issue deeper?
