Rated 5 out of 5 by from Great replacement valve Absolutely delighted with this purchase. We have mains pressure on the high side at 65 PSI. This valve fills much more quickly than one it replaced (which correctly had a flow restrictor fitted). No need for a flow restrictor on this unit. And although more noisy during the filling process, it is not an issue as it fills so quickly. That is a Big bonus! Best thing about this bit of kit is the brass shank, and the flat section on it, to enable a spanner to be used to nip up the brass tap connector nut without stressing the cistern or plastic valve unit. The only change I made during fitting, was to swap the supplied flat rubber sealing washer, for one that was tapered, thicker at the centre section, to get a watertight joint without too much torque on the plastic securing nut. Overall, very impressed and would buy again.

Rated 5 out of 5 by from easy fit Glad i went for this,the one i was replacing had a plastic shank and the threads were stripped.this one has brass, much stronger,this was very easy to fit didnt even have to adjust the height,went straight in,only thing i thought was better on the old unit was the nut to go on the shank was thicker with a shoulder,so i re used that,otherwise cant fault this recommended

Rated 5 out of 5 by from Well worth the extra money The brass shank, with the cunning filed-off part that takes a spanner, really helps. It lets you tighten the nut on the cold feed just that crucial extra bit, without putting strain on the valve assembly itself or the cistern. Beware the cheaper alternatives, which also often don't actually work .

Rated 5 out of 5 by from Well worth the money Easy to install and adjust. Quick fill and precise shut off. Wish I'd bought one of these before!

Constant drip

Fitted this today. Unfortunately there is a constant drip from the blue spout even when the float has closed inlet valve. Should I return this as faulty? Or is there a quick fix that would save the effort of removing it and returning to Screwfix dept
Asked by: WalterP
Try dropping the extension section a little and ensure the blue float is at 90 degrees when the water shuts off, had the same issue and with a little adjustment I stopped the drip,

Quiet filling?

Fitted this fill valve recently.It is not so quiet filling as suggested,in fact it is quiet noisy.Do you have a quieter model? I have tried reducing the pressure but the toilet takes an age to fill.
Asked by: Animal78
Due to a recent change in the Water Regulation Requirements for Inlet Valves, we are no longer permitted to supply these valves with Silent Fill Tubes as was previously the case. We have made modification to the overhead discharge nozzle of the valve, to try and reduce the noise levels as much as possible, However, the level of noise is going to vary from Installation to Installation depending on the operating water pressure.

Hi, I am wanting to replace an existing fill valve and wonder if the brass tail length is adjustable to fit exiting pipework?

Asked by: TryingHard
Normally all 1/2 inch tap connectors, so this will fit, never had a problem. Hope this helps.

Is the brass tail threaded for Euro or UK fittings, please ?

Asked by: CGDiy
Good afternoon CGDiy, I can confirm that the Brass Tail thread for the Dudley Hydroflo is standard for the UK market which is 1/2" BSP, used for 15mm pipework. European equivalent would be 3/8" BSP used for 10mm pipework. For reference if you need to fit the UK standard 1/2" BSP to a European 3/8" 10mm, a Reducing Coupler would complete the job for you which can be found at Screwfix using code: 51238. Hope this helps? Happy Plumbing, and feel free to let us know how the project went. Best regards, Chris Marsh. Thomas Dudley Ltd.
