## Description

From the manufacturer

Review: Great product - 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.
Review: Fixed my problem - 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

## Questions & Answers

**Q: Why have a brass shank? It cannot be held when tightening the pipe joint. It still has to be tightened against the seal/ rubber seal friction.**
A: so that it does not cross thread

**Q: What is the diameter of the threaded brass shank**
A: Threaded brass shank is 1/2”.

**Q: Would this be suitable for a modern macdee cistern the valve bad design isnt working right. thanks for any help**
A: Might be a case of checking the height of your old one against. I'd think you could use any type of fill valve if you had space in the cistern. But same as Dennis, not sure. I replaced a terrible cheap fill valve with this about a year ago and it has really made the difference (15 minute refill to less than 10 seconds).

**Q: What water pressure does this product handle please?**
A: The water pressure recently tested at my property is 9 Bar and I have had this in over 2 years with no problems but the Armitage Shanks model gave me a lot of trouble.

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐⭐ Fixed my problem
*by B***Y on 7 September 2025*

### ⭐⭐⭐⭐ Good, simple to fit, though they ought to provide a brass backing nut...
*by F***N on 28 November 2012*

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.
