      Alan Oakes

    • Very efficient and arrived as promised next day.

      Colin Hall

    • Goods news I could still get parts for my Mira shower. Was a perfect for the 415 model. The other half fitted the valve with no problems and was quite easy to connect and took about 10 minutes. Part was delivered next day which is great and disruption to my hot shower.


    • It works.

      Adrian Peters

    • The Mira replacement cartridge arrived very quickly and was exactly what I had ordered. After applying the supplied grease to the seals, it simply slotted in to the body of the shower, which I had stripped down. No more leaking shower! Thank you NSS for excellent service.

      Andy Minniss

    • 5 stars for the service of NSS. Excellent next day delivery. Mira cartridge did the job, but so expensive. NSS has best price though.

    Ask a Question

    • My Mira 415 mixer shower was installed in the early 1990s (probably 91 or 92). Is the grey cartridge the correct one to fit?

      Part number 902.91 (grey) will be the correct version installed before 1993


    • What do you do with the silicone included ?
      Is it wise to purchase the O ring service kit too ?

      Hello, the grease is to smear on the seals, to stop them binding when installing the cartridge into the body. It is always handy to have a seal kit, as some of the seals do not come with the cartridge.

    • Can I fit this in place of a black cartridge?

      No, there are no inlet check valves in this cartridge they are built into the valve body, if you fit the 902.91 instead of the 902.55, you will not have any check valves and you could get bad water hammer, vice versa, if you fit a 902.55 inplace of the 902.91 you could end up with double check valves which could upset the combi boiler, always fit like for like
