Genuine Hudson Reed/Ultra/Crosswater replacement Thermostatic Cartridge - SC50T20

Took a chance on this cartridge. Thought the price was too good to be true - other retailers sell the same cartridge upwards of £90. Works perfectly and fixed the problem. Shower wasn’t getting hot enough. Managed to change it myself without calling out a plumber. Happy days!

Good item, works well resolved the pulsing pump issue that the customer was having with the original one, fitted well, loosen and tightening the retataining nut was the most difficult part, customer left the cover plate off for a couple of days to ensure there was no leakage, for its price if it lasts a year that's fine

Good replacement good price

My shower had been losing pressure for a long time and, typical of builders everywhere, the thermostatic mixer was not fitted with water isolation valves and access to the mounting screws was blocked by over enthusiatic tiling and plasterboard. This meant either a very involved, destructive job to change the whole mixer, or opting to try this replacement cartridge.The hardest parts of this were:1) Remembering to turn off the stop cock and drain the pipes (see above lack of isolation valves)2) Getting the retaining nut off the existing cartridge - this was a ~55mm diameter nut that clearly required a specialist tool that I didn't have, didn't know the name of and didn't want to buy as I am sure it wouldn't come cheap. It was made even more difficult by poor access. I finally managed with a pair of water pump pliers (joint pliers) and a lot of patience.3) Removing the old thermostat just involved pulling it forward - though this required a reasonable amount of force, so fortunately the mixer housing was well-secured to the wall! Once it started moving, I had to compensate quickly to stop my elbow smacking into the glass shower wall behind me - it comes out with a pop!After that it was plain sailing. As other reviewers have said, the o-rings on the new cartridge were a lot thinner than the originals, so I swapped them over, cleaned and re-greased them, slid the new cartridge in and put everything back together. The shower works a treat - I needed to adjust the temperature setting a little on the new cartridge, but now it's never been better. Fingers crossed it lasts!

Worked perfectly and very good price.

Unfortunately I cannot review the item in terms of operation as it arrived broken.
