Reviews
Thomas Dudley Beta + Part 3 Adjustable Float Valve Bottom entry is rated 2.4 out of 5 by 23.
Rated 1 out of 5 by from Does not shut off flow Fitted one today as replacement for 25 year old valve. nice to adjust and wall made BUT the principle job is to shut off flow at required level. this one continued to dribble. Very ann oying. Removed and fitted another... even worse, you could hold float arm up high to no avail. Took them back and fitted Opella.. no problem.Not at all pleased with Dudley waste of an hour today.

Rated 3 out of 5 by from okay but Does the job but a little flimsy for my liking and had problems making it stop the water flow despite having the correct pressure fitting

Rated 1 out of 5 by from Looks great The design of this valve just does not work, the adjusting screw that controls how high the water is, is not central to the shut off pin and causes it to bind and not stop the water. I have spent hours fiddling with it, replacing all internal parts and the water does not stop.

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.
