    • excellent service and web site,
      thank you ! and Merry Christmas

    • Replacing this part has completely transformed my shower from useless to great. Installing the part wasn’t too difficult either.

      Adrian Riches

    • This was a 2nd bite of the cherry after I had misidentified and ordered the wrong cartridge, but the correct carrier the first time around. The NSS team identified the correct cartridge from a photo I supplied. I returned the cartridge, a full refund was credited and the correct part (i.e. this one) was invoiced and supplied very quickly. The modern part supplied today - and the temperature handle carrier - is an improvement on the original design. Installation was quick and easy and worked perfectly straight off the bat. Great service as ever.

    • The temperature control on my Trevi Therm mk1 shower had stopped working so I identified the correct replacement cartridge using the very handy diagrams on the NSS website. Without these diagrams I am not sure I would have risked buying the part but instead gone for the much more expensive option of fitting a new shower. The cartridge arrived quickly and was an original Trevi part.
      As other reviewers have said the tricky bit is getting the old cartridge out. As the shower was built-in the usual adjustable spanners did not reach so I found an old box spanner of around 25mm which (after a bit of filing) fitted. I had to carefully use my biggest monkey wrench on that to start the cartridge turning, but once it was moving it came out easily.
      The new cartridge has cured the problem and the shower is now as good as new.
      So - many thanks to NSS for their excellent website and high quality service!

      Colin Carron

    • Great service from NSS, fast delivery, will definitely use again and would recommend. I ordered the wrong part the first time and the return was easy and the refund prompt.

    • We had our Trevi shower unit fitted in 2002 and the water control is sticking sometimes so the hot water doesn't turn off. It unclogs with turning back and forth. My question is 1. Can the rubber rings be replaced easily or must we replace the whole cartridge? 2. Will this cartridge fit a unit from 2002.
      Can you send me an on-line diagram of how to replace the cartridge please.
      Many thanks

      if shower will not shut off you require part A952501null flow cartridges, A96048NU gear cogs
      If tempreture is at faulty you require S960134NU thermostatic cartridge.

    • Hi, how do I know if this will fit my Trevi Therm

      Hello, this 963068 Trevi cartridge will fit the older style Trevi Therm, the way to check is via the handle, the old style Trevi Therm has four finger grips on the handle where you grip to turn it, the new style has just two flat sections
