Fluidmaster PRO45B Fill Valve with Brass Shank - Black

This is a great product. I had a problem with the fill valve slamming shut on a toilet and cycled through a number off competitor options which didn't not solve it, before alighting on this one, which very much did. The fill flow was also not materially reduced by the valve to make this happen. The brass shank is a "nice to have" that makes it easier to mate and tighten a connection to it when it's in a tight hard to reach spot. Also the narrow profile of the valve is much better suited to slim cisterns compared to some competitors which couldn't fit into the cistern properly without a lot of manipulation.

Brilliant. Fixed a water bang 💥 when the cistern stopped filling. Could only have the water isolator valve open a 1/4 of a turn which made a loud water filling and took longer to fill. Now the isolator is open fully, it’s quiet, fast and fixed the problem with bang. Easy to fit

Its nice and adjustable in terms of pipe height and the float height. Also would've been super easy to fit, unfortunately my pipes don't line up nicely as they do on all those youtube tutorials. This meant I had to ensure the bottom was tightened up much more than recommended to ensure the washer sat nice and flat at the bottom of the cistern, to avoid a leak. I had to purchase a brass backing nut separately to solve my particular problem, but as it has a brass shaft they could've supplied a metallic nut as the threads are less likely to get damaged. Either way a good problem and sorted out my water hammer problem. Oh it also comes with an restricter which you can optionally fit to further reduce water hammer, I fitted the restricter anyway.

Easy to replace. High quality.

Ordered this as a like for like replacement after the rubber seal on the old one (which I would guess is 15 years old or more) gave out. Easy to install and works straight away without too much fiddling. Relatively adjustable. I would prefer a metal backnut but the plastic one supplied with this kit is perfectly serviceable

Initial impressions after a few days of installation are positive. Having had a previous inlet valve (fluidmaster 400A) replaced with a like-for-like replacement this was soon followed by water hammer, occurring when the adjacent sink tap was turned on whilst the loo was refilling after flushing. I had 5 different plumbers in to try and fix the problem. This ended up costing me hundreds as I had a new tap and a water hammer arrestor fitted. But neither helped fix the problem. Partially closing the loo and sink valves decreased the hammer but made the noise from flushing or the tap much more noticeable throughout my house. I saw the Fluidmaster 45b advertisement saying it stops or reduces water hammer and so decided to give it a go. I also viewed the fluidmaster bottom entry inlet valve installation video on YouTube, and decided I'd give it a go rather than pay another £80 to a plumber. I found the installation just as easy as the video suggested. Upon removing the old valve I noted it did not contain the small water pressure reducing 'bung' and so ensured I fitted this (supplied with the 45b valve) into the 45b prior to installation. I believe this device, along with the brass thread at the bottom of the valve is the reason why (fingers crossed) the water hammer has now disappeared whilst the refill is ultra quiet, even with all valves now turned back to fully open. If only I'd done this from the outset I'd be about £400 better off!

Quality item. Fitting was very easy.

Good replacement. I'm no plumber but managed to fit this to our consealed cistern and resolve our leak issue. Brass shank is a bonus, faulty one was plastic. Edit: This valve developed a fault a couple months after fitting. Now sticks after flushing and have to run cold water tap to get it to release. Can see from other reviews this is a common problem and possible design flaw. Have to put up with it for now until I can get the panelling off to check the concealed cistern. Very frustrating, but at least there's no leak.

Risolto ogni problema.

Utilisé en remplacement du modèle identique, qui avait tenu 15 ans, et a cessé de fonctionner à cause du calcaire. Produit très qualitatif. Bien noter que le filetage mâle est en 1/2 pouce.

Fungerar perfekt i mina Gustavsberg Nordic toaletter. Enkelt att ställa in och montera. Fyller cisternen snabbt och relativt tyst (med 5bar systemvattentryck).

es de inglaterra, así que aquí no valen esas medidas, no son los estándares nuestros, es producida por los hijos de la gran bretaña

sehr gut
