      Clifford Barber

    • Quick delivery, Very easy to self-fit the cartridge, bought to replace older 'faulty' one, did not initially fix hot/cold shower issue. turned out to be our new boiler's (18mths) DHW setting was far to high (as set by installer), reset DHW setting lowered to 'ECO' normal
      temperature, is much more constant & stable now thanks.
      Thanks to NSS.

    • Hi, I have this cartridge and the hot and cold settings are all to cock when I tried to clean it. Does the new one come ready set for use? Do I just pop it in and away you go? Thanks

      Hello, it is ready to fit, you may have to tweak the max temp setting, full instructions in with the new part.

    • I have a Mira excel shower post 2002 and the hot water supply stopped so I pulled the cartridge out and found that the hot water inlet wasn't opening as the plastic that slides the Bakelite plate has snapped. just wondering if that part can be sold separately?

      Hello, very sorry, but Mira do not do spares for the cartridge, just a complete cartridge.
