Thomas DudleyHydroflo Bottom Entry Adjustable 1/2 inch 15mm Brass Inlet Float Valve 324302, Multi-Colour

Bought to replace a constantly leaking plastic version, this is quick and easy yo install, and has not had any overflow issues for at least a month

This has been installed and used for a month now and so far, seems fine. It’s quite different to the traditional ballcock system...the float is tiny. The image on the box showed a silencer tube but none was provided although I don’t find that a problem. Our water pressure is fairly low and actually hearing the cistern fill...or more importantly stop filling, gives a bit of confidence that everything is working as it should!My main concerns relate to the physical dimensions. I installed a Thomas Dudley Turbo Flush at the same time and with my cistern configurations, there’s not much room to get the Hydroflo in as well. It seems very close to the Turboflush but is working fine so far. It’s also a bit obstructed by the flush handle so that would have to be removed for service etc.The biggest problem though was the height relative to the close coupled cistern lid. That lid has a nib running all around it’s underside so that the lid sits on the cistern and won’t slide off. However because the Hydroflo is quite high and is fixed close to the cistern wall, the top found the lid so that the lid won’t go fully down. In my case, I’m pretty practical and have a decent workshop so with a lot of care I used a small angle grinder to cut off about 150mm length of the nib. I took that very easy, didn’t want to crack the lid but by nibbling away, it only took a few minutes and there’s plenty of nib remaining. That solved the problem and now the lid fits without fouling anything.So overall, having now overhauled the cistern with everything working OK, I’m pleased. It’s a bit fiddly, could be easier and instructions could be improved, but it isn’t rocket science. Grinding the lid seems rather major but in reality wasn’t an issue. Am I glad I bought it now? Yes I am although that’s partly in the hope that it won’t need touching for a good many years! Would I recommend others to buy it? Yes I think so...it seems well made and is serviceable with many parts available on the Thomas Dudley site ...just be careful about the dimensions!

Easy to fit, fills cistern quickly and quietly, good construction means it shoud last many years, I would recommend.

Does what it is supposed to do and simple to fit. It is however noisy - ? valve resonates throughout the fill process.

Excellent well designed and quality product. The Aston Martin of the valve world. Get what you pay for. The labour is the same if you fit a cheap one from China or this one made in the UK which given the standard of materials should last a long time.

I am not a plumber and this is a newer version than my old one. It does it's job but I hope somebody gets well paid to come up with all these fancy designs to replace older but workable models. One thing I have noticed is that it is just a bit slower to refill the cistern.

Not at all satisfactory when that joint in the mains is below the level in the cistern. If the joint leaks (bypassing the float valve) and it is below the overflow level the water consumption rises alarmingly and only the water bill may reveal this. This happened to me after it was installed by a plumber!

Very easy to fit and set up. Quiet in operation and reasonably fast to fill. Already assembled so no IKEA moments.
