Fluidmaster Bottom-Entry Bottom-Entry Fill Valve UK ½" is rated 4.7 out of 5 by 426.
Rated 4 out of 5 by from Great product I bought one of these before, to replace a broken unit - and it's still doing the job. A more expensive one failed in less than 12 months. Clear instructions for those who are not too confident, but mine was ready to go in no time at all - FANTASTIC value

Rated 4 out of 5 by from Shame only one rubber washer This is a great product and easy to fit. My only annoyance is that only one rubber washer is provided (to fit inside the cistern). Fluidmaster could have provided an extra washer to seal the join outside the cistern as well for a few pence (so providing a more secure seal to avoid water leakage). I do have a concern that such penny pinching may also have been applied in other areas of manufacture, but time will tell!

Rated 5 out of 5 by from Excellent valve This is theh second one I've bought from Screwfix so reliablility etc. is based on the performance of the first and influenced the putrchase of the second. Very simple to fit and to adjust. just rewuires a bit of patience to fit it so that it doesn;t interfere with the syphon mechanism.

Rated 5 out of 5 by from Excellent Replacement Valve The flush would not stop filling up, the rubber valve had gone on it and was unable to get a replacement as they do not seem to produce the same type any more. It is one of those compact toilets, swapped out the old fill valve for this one. Really easy to fit and setup. Quiet and works well.

Rated 5 out of 5 by from Well designed valve Easy to fit and adjust so not much more needs to be said. It just works as expected. Cannot rate reliability as only fitted 2 days ago. This should be an option as not valid to give a value straightaway!
