      Vinesh Chauhan

    • Very happy to even get this valve. It was difficult to identify even with a drawing.
      Thank you so much. FYI It fitted into the installation just fine but, the water would not turn off! I removed the cartridge and checked it. The only difference was the length from the blue seal to the contact face at the root of the thread. It was 1mm shorter.
      To resolve I fitted the used blue washer from the old unit. Works fine.

    • I contacted NSS for help in replacing a leaky cartridge, Daniel provided the info for what he needed to find a replacement. After several emails he recommend the best alternative, although he couldn't provide the exact replacement I managed to modify the the new cartridge to fit. Overall I found NSS very professional and helpful to deal with and highly recommend them
