      Duncan Snow

    • Very fast delivery very good price and a great product.
      Simple to fit and works perfectly

      James Bower

    • Once the water is turned off, this shower is a delight to work on. once the control levers and trims are removed the cartridge is held by four screws, once removed the cartridge will be able to be pulled from the valve body. ensure the old seal is removed along with the inlet filters. the new filters fit in well, grease the inlet seals and slide in the new cartridge securing it with the four screws. Total disassembly and refitting time was under 10 minutes.

      Mark Rose

    • We purchased our cartridge assembly on line which was very easy, the video was excellent and very easy to understand and well executed, cartridge arrived on time and well packaged. Watched the video and fitted with ease. The two filters inside we found exceptionally useful as ours had blocked. Only 1 thing that we could say needed was more grease as it came in a tiny little plastic tube and there was hardly any in. Overall from watching the Video to ordering on line and fitting excellent and would highly recommend

    • 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.

    • how do I stop my Excel from dripping

      Hi, you will need to replace the Mira Excel cartridge 451.71, there is no way to recalibrate the cartridge.
