Fitted Today -For our customer in Sutton Coldfield, this Triton Mersey shower bar. Note on start up it is in the cold temperature position - When the temperature is raised see the pressure increase, this is because we installed a pump below the water cylinder. The installation took 1.5 days - We got our sparky to utilise the emersion heater switch by upgrading the Mcb. We issue an electrical test certificate with all new electrical installations. The cost for the new bar shower, pump, pipe work, tank & cylinder connections, electrical upgrade and certification around £1150. Call for a survey.
