    • paid for next day delivery, arrived on time, fitted and working in half an hour.

      David Morris

    • Seemed a little bit daunting at first but simply follow instructions and all will go well. Make sure to transfer the two large O Rings in the old valve to the new one. There's a small O Ring inside the switch unit at the top. Make sure its seated correctly. Would suggest you remove it with toothpick or like and fit it onto white pipe.

      Mike Boyle

    • Good replacement part. Does what it is meant.


    • the part came 2 days after re-ordering (which was my own stupid fault as I failed to supply the house number on the initial form, many thanks to Mr Gary Westlake & crew for a sterling service) it came with clear, concise, perfectly understandable instructions, I installed it in under 15 minutes, & it works perfectly,, I cannot recommend NSS shower supplies highly enough, a quality firm providing first class quality components.!

      Michael Hodgson

    • Speedy and efficient, thanks.

      Mr Garlick

    • Product arrived within specified time and was easy to change. Customer well satisfied.

      Mr Smith

    • First replacement only lasted 2 days so I was a bit concerned. However when I rang up I was treated with courtesy and a replacement was sent out immediately without question. The replacement has been working perfectly ever since. I can and will recommend NSS to anybody requiring parts. The faulty part was returned at no cost in a prepaid envelope.

      Peter Owen

    • Product is a like-for-like replacement. Exact swap out, no issues. Was brought to replace a faulty solenoid that was causing the shower water supply to shut off after a few minutes.
