Trevi term replacing cartridges

Reviewed 4 years ago by Colin Campbell
Have mark 1 Trevi Therm shower unit which was sticking when turned to off. problem was the hot cartridge was stiffened up with scale residue and the gear wheel was slipping as it tried to turn cartridge. These cartridges were the best value i could find. It was straight forward replacement job. Use a 22mm tap spanner to get into the wall where the cartridges sit. So far so good. Recommend!
