Thomas Dudley Beta + Part 3 Adjustable Float Valve Bottom entry is rated 2.6 out of 5 by 19.
Rated 3 out of 5 by from Won't stop the water - have I cracked it (hope so) I cannot work out how to edit a previous review so have done another with average scores. I pray I am not tempting fate. A recurring issue is that the valve will not stop the water. I had this issue and as a last resort took the valve apart. I took the arm off and put my finger over the spout/seat/or whatever they call it (the red or white thingamijigs that look like cluedo pieces and that the water comes out of). It seemed loose and water just came round the side from the back. The spout was not being held firmly enough against the o ring behind it. I took all the innards out and found the back and o ring were wet. After a chat with the technical chap (number in a reply to an earlier post) I swapped the white spout for the red one. Armed with my trusty tube of fernox sealant and coated the back of the spout and o ring and reinstated. I then gave the cylinder that retains the spout a firm push (is this all that was really needed?) and it seemed to go in a bit further. The spout didn't feel loose when I tried to move it. I also gave an extra turn when putting the large retaining nut back. I had it out and in the greenhouse connected to the main via the garden hose. I tested quite a few times over a bucket (using the water for the plants) and it worked fine. It is now in place and connected and (fingers crossed touch wood) is working ok. When I am confident I will finish the job. So, is the spout left loose so you can change more easily before installing, or a manufacturing fault that is not pushing the internal retaining cylinder in enough. Before installing, check to see if the spout is loose. If so, give the retaining cylinder a good firm push so the spout is held firm against the o ring.

Rated 1 out of 5 by from Unadjustable I am not a plumber but have installed or replaced a few systems over the years without any trouble - old brass and plastic. But this one. So temperamental and unreliable. I went to buy a different one that was out of stock. This only needs to last until the new owners move in and strip out the bathroom (their stated first job) so I thought, it should last that long. As a consequence I am loath to dismantle it again. I have tried adjusting this so many times in a week or so. Each time I set to where I want, flush a couple of times and think job done. However, one occasion heard water running and found cistern overflowing. Adjust a bit more. Next time it switched off prematurely and wouldn't flush - not enough water. One time it just wouldn't switch off even when I lifted the ball up or pushed the button manually, and had to switch off at the valve on the inlet pipe. I will try again - reset/dismantle check top end internals. However, it is looking like a return to Toolstation is on the cards. I suggest Toolstattion stop selling this one.

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
