Fluidmaster Side-Entry Fill Valve ½" is rated 4.5 out of 5 by 107.
Rated 5 out of 5 by from Simples Easy to fit and quieter than the valve it replaces. 3 stars for reliability simply because a few days use is too little to judge.

Rated 5 out of 5 by from 2nd time used Bought this Fluidmaster for a concealed wc cistern about a year ago when the ball valve needed replacing - fitting was simple and it has proven 100% reliable and quiet so I didn't hesitate to buy the same again when a second concealed tank needed updating. Only thing to watch is if the flush handle is the same side as the inlet there is a potential conflict with the siphon housing which is on the same side as the float cannot go down to the bottom. As I needed a higher fill level this was no prob to me but otherwise a newer style of flush would be needed.

Rated 4 out of 5 by from Good Quality but Pricey Bought this to replace a broken one that came with the toilet 6 years ago. I would not say it's silent but once the water has filled and it is below water level, it is quiet. It is well built from rigid plastic but I think it is expensive for what it is.

Rated 4 out of 5 by from All quiet on the western front I fitted a traditional valve with long arm float a couple of weeks ago and although it worked ok the noise from the header tank filling was something else.I swapped it for the Fluidmaster in fifteen minutes yesterday. Peace prevails and the neighbours are talking to me again. It pays to read reviews before buying. A lesson learnt.

Rated 5 out of 5 by from Improvement out of necessity! I think I've become a Fluidmaster fan! - We have two loos and I've replaced the siphons on both with their push button cable valves. - I had already replaced one of the "floating" side valves with one of these almost-silent fill valves so when the other one failed I bit the bullet and replaced that with one of these too. - Very easy to fit and it works exactly as expected.
