Fluidmaster 1/2" Brass Shank Valve Bottom Entry is rated 4.6 out of 5 by 54.
Rated 5 out of 5 by from Excellent quality product I purchased this item recently to replace an old armitage shanks valve, very easy to install and in my opinion a much better designed product. Have used Fluidmaster valve’s in the past and always been impressed with their Product would throughly recommend.

Rated 5 out of 5 by from Well made Fitted one last month and performing well. Sturdy brass inlet - permits good joint dis/reconnections. Mechanism is clever, set up instructions are good. Preserve them for future and you have a long life serviceable float valve - diaphragm seals are available.

Rated 5 out of 5 by from No more cross threads I bought this to complete my cistern refit. As the old supply valve was cross threaded and leaked. Not anymore. This is the way to go. The valve fills the cistern quickly.

Rated 5 out of 5 by from Silence is golden I bought this on the advice from an online plumber. I had severe pipe hammer when flushing the upstairs toilet. This cured that problem instantly. took about 10 minutes to fit and is nearly silent in operation. you do need good eyesight to be able to read the instruction shhet though.

Rated 5 out of 5 by from Replaced a dripping Torbec fill valve The brass shank was the main attraction along with the positive reviews. I bought it to replace a dripping Torbec valve - spotted after I had posted a positive review of the Torbec valve! Torbec have changed their design and this seems to be a common problem. The Fluidmaster valve is well designed, pretty quiet and gets good reviews, although you can't see if it starts to drip as the water enters at the base unlike the top feed of the Torbec. It's height adjustable so gets round the problem of obscuring the mounting screws on my close coupled cistern. Close coupled toilet systems are pretty hard to work on, plumbers definitely earn their fees!

Rated 5 out of 5 by from Compact and easy to fit I like the design, simple and compact and really easy to adjust the water level. Ideal if you're replacing the long arm and float type where there's not much space between the siphon mechanism and flush handle
