Thomas Dudley Beta + Part 3 Adjustable Float Valve Bottom entry is rated 2.7 out of 5 by 17.
Rated 1 out of 5 by from Faulty The valve worked a few times then simply refused to shut off the supply. Took it apart and checked correct high pressure collar installed. The diaphragm rubber perhaps is not compliant enough ? Our water pressure is limited to 2.5bar. With the valve leaking no amount of lifting of the arm will close the supply so not an arm/float issue.

Rated 1 out of 5 by from Does Not Work Bought this to replace existing fill valve which kept detaching its ball float and thought this was what I needed but I`ve been unable to use it as the "valve" keeps sticking and not closing the water off resulting in overflows. I tried changing the ballvalve washer and thought that this had solved the problem but alas no; same problem this morning on first flush. The sticking valve was so severe that the ball float was almost fully submersed and still allowing water to flow into the cistern ( I had to shut off water supply ). I had noted when changing the washer that the existing washer appeared to have been inserted the wrong way round and I thought this may have been the cause of the problem, but obviously not. So back to where I started; I`ve writtenn this one off so I`ll buy another new fill valve but definitely NOT a Dudley. Final observation on Dudley`s valve: graphic fitting instructions on package need some narrative to fully understand; easily / quickly extendable float arm isn`t ( have they glued the two arms together, I couldn`t budge them and feared that they would snap if pulled too hard); where is Dudleys Quality Control ?; why bother giving 3 year Warranty when it doesn`t work in the first place.

Rated 5 out of 5 by from Works well Bought this to replace existing ball float. Range of adjustment both on length and lateral adjustment is VERY helpful. Worth remembering to ensure the ball float is fully tightened onto the swivel joint so that it locks into place. These types of ball float valves are a more gradual slow shut off, so do drip for quite some time. You can buy more modern valves, but they sometimes have water hammer issues where you get banging pipes from the water being shut off fast. So, depends on your water pressure. Also, be sure to use the red pressure seat supplied, if you water pressure is low.

Rated 1 out of 5 by from Water valve didn't close I struggled to get a seal as the washer was more flimsy than the existing one. The water valve didn't close just kept dripping

Rated 5 out of 5 by from Successful Fix by average DIY'er Was exactly what it said, I'm no plumber but had managed to identify the faulty part in my cistern that was causing a leak and although I wasn't sure of the exact part I needed, and this was not identical, but similar it allowed me change the whole of the incoming flow and the cistern is now fully functional with no leak. Only took about 30 minutes for the whole operation.
