Rated 5 out of 5 by from Top Quality after 20 years As previous reviewer states great service from Bristan via SF shower mixer is 20 years old, cartridge replaced with little drama. Getting the old one out was a bit of a challenge but followed the advice in the downloadable instructions worked (refit the flow control knob and circlip then lever off with a screwdriver between control knob and mixer body)

Rated 3 out of 5 by from 3 out of 4 seals wrong way Checked the product on arrival and as warned by previous reviews I have found that 3 out of 4 seals were wrong way round. Some Reviewers found it was easy to turn them around, but not me. The seals were very tight and I really struggled to take them off without damaging them (both cold and warmed up). Finally after an hour I managed to take them off and turn them around. Putting them back was much easier. Just installed the cartridge and no leak so far (waiting for hot water to heat up to check again. time will show the reliability). Other disappointment, the cartridge comes without the grease, which I had to buy separately. My questions to Screwfix: First, why do I need to spend my time fixing the wrong installation of the seals which supposed to be done by the manufacturer (and included in the price)? Same product is sold by several other suppliers even cheaper. I choose Screwfix due to its brand and expecting a decent quality of the product and not to correct the manufacturer's assembly errors. Second, why not to include a sachet of silicon grease that is required for cartridge installation? Or at least make it available to buy and add to the order?

Rated 4 out of 5 by from Bristan 1901 replacement Cart5 Great replacement for my concealed Bristan 1901 with a Cart5 thermostatic cartridge. Comes complete with new rubber seals :-) and the cartridge retaining plate (not really necessary) Only the front 3 V-section seals were required for my model. Make sure they are fitted correctly as per diagram and do not trust factory fitting (2 were back to front)! Chose to slightly shamfer the rear spline for an easier push engagement. Retain the small O-ring off your original cartridge to keep the rear spline "dry". Do not grease this - it could become hardened and fastened in over time! - ask me why I am changing *the whole* cartridge??? Had to also slightly file down diameter and recut the front splines with a v-shaped file on the temperature control for a smooth fit. Do not force it on! Otherwise all good and for an excellent price and availability. Thank you Screwfix.

Rated 4 out of 5 by from Mixer valve As others had mentioned the smaller 3 seals were not the correct way around when compared to the pdf install sheet. Easy enough to swap around. Outer spline was also too big for the handle/knob to be fitted so maybe if you do buy this test that first before dismantling the whole thing. Can’t really note reliability as I returned it.

Will this fit a 2001 Prism Mixer Valve?

Asked by: Myosotis
Couldn't find a model number so took a chance and ordered a new one (can always return to SF) It was identical to the old one so I fitted it, shower working OK. Well done for supplying spares 20 years later! Only difficulty was getting the old one out, lime-scaled in but followed the advice in the PDF instructions on the product page and came out OK

Suitable for a 2007 1901 exposed shower valve ?

Is this cartridge a suitable replacement for a 2007 bristan 1901 exposed shower valve ?
Asked by: AndyMartin
Yes, mine is a concealed Bristan 1901 fitted in 2005 (I think). The 4th rubber seal nearest to the ceramic valve is not required (this was added later, I think to keep the rear shaft fixing spline dry) My rubber seals lasted 9 years before needing to be refitted. Had to refit a whole new unit, though, as the splined stud would not pull out of the recess without breaking - doh!
