Fluidmaster Bottom-Entry Bottom-Entry Fill Valve UK ½" is rated 4.7 out of 5 by 436.
Rated 5 out of 5 by from Not good for plumbers... I say not good for plumbers because once you fit one of these you never get called back to that customers toilet :) Reliable, decent price, last for ever. Only niggle I have is the plastic shank but Screwfix also do a brass shank version of this. Plastic is ok if you're connecting with a flexi but it's easy to cross thread the plastic with a brass tap connector fitting. Always renew the red fibre washer too on the brass tap connector.

Rated 5 out of 5 by from Good Product Got this to replace a 10 year old one that kept over filling , easy and simple install. Being able to adjust the height of the overall unit made it fit very well to an odd shaped cistern . The only downside is the float adjustment could do with being slightly longer as mine is maxed out at its lowest position to get the water level right. It's been in a few days now still working perfectly.

Rated 1 out of 5 by from Not universal Not universal. Didn't fit my toilet, brushed against the inside of the fill bowl. Not happy. Terrible product.

Rated 5 out of 5 by from Fluidmaster fill valve Great product, 2nd one I've brought to replace cheap Torbeck valve's that were fitted by Barratt homes. This item is easy to fit and a straight replacement, easy water level adjust and fast filling so well pleased. only gripe is that you can't get a spanner on the fitting nut but a pair of grips does the job but don't over tighten it just pinch it up.

Rated 5 out of 5 by from Good quality item This item was well made and it was a very easy to install. Liked the adjustable length, the rubber washer was nice and thick. All in all very good product and great value for money!

Rated 5 out of 5 by from Hot flush..! . Perfect replacement internal bottom entry filler, easy fit, easy to adjust, VERY quit fill, why pay more when this one does the job!, Perfect for the smaller modern toilets, where space is limited.. Used many times before, Very reliable product.. Tip... Do not overtighten.. As the rubber seal will distort and leak! Hand tight, good enough, can use Screwfix no-nonsense clear sicone, as an extra seal..!
