Fluidmaster Bottom-Entry Brass Shank Fill Valve ½" is rated 4.8 out of 5 by 59.
Rated 3 out of 5 by from Good but a bit complicated I bought this as a replacement fill valve. Got a shock when I opened the box as the float is the diameter of a domestic coffee mug. I thought it would fit into a neat corner but was far too big. Cistern had spare entry point so it fitted there and I had flexible acorn piping for the transfer. The instructions are good with the exception of the step to flush the system after the device ad been fitted. It was impossible to remove the cap while holding the stem. I had to disconnect the water from the valves stem remove the cap then flush then disconnect again and replace the cap and then turn on. (will prob have to do this again to service it) The valve works well but alot of work and attic trips for a DIY , plumbers prob fine.The valve cap is very stiff to remove. It is slower to fill(fills from bottom up) than the original but works well and is very quiet. Not sure I would recommend for a novice!!

Rated 4 out of 5 by from Excellent This valve fills very quietly and very, very much quicker than the old floating ball cock it replaced. The water flows in at maximum speed till its full, instead of getting slower the nearer it gets to the shut-off point, like the old ball valve assembly did. Its extremely compact design makes it easy to fit, even very close to the cistern wall. Adjusting the fill level is quick, easy and very positive. IMHO the extra for the brass tail is well worth it to eliminate any danger of cross threading. Reliability - installed 1 month ago and its fine so far.

Rated 5 out of 5 by from Reliable One thing a Plumber hates and thats call-backs by a customer. That's why to prevent this we fit this valve with its brass shank. We will never fit a plastic shank valve again. Metal beats plastic hands down and there's no cross threading or leaks. 100% reliable.

Rated 5 out of 5 by from The best Don't muck about with anything else. I bought this to replace a Torbeck float valve which failed less than 24 hrs after install and was no cheaper than the plastic shanked version of this. The brass shank version is worth it for extra peace of mind and a real quality product. Either version fills extremely quietly, quickly and has a good positive shut-off.
