Rated 5 out of 5 by from Quality and good value Note this product comes with a 5 year warranty if you register your details within 14 days of purchase. I dont' think there are (m)any other syphons for this price with this level of reassurance. Plus it's made in the UK. I am an average DIYer and fitted this end to end in under an hour, including having to free some corroded screws holding cistern to wall. Order a new close coupling kit at same time as the old one will probably be disgusting. There is a QR code for installation guide on the packaging; or just search youtube - though easy enough without those too if you are reasonably competent. I've only marked it 4/5 for reliability as cant' really comment on long term, but with guarantee, don't foresee any issues.

Rated 4 out of 5 by from Almost perfect Can't beat it for price - no point getting anything dearer. Has options of 9ltr, 8ltr & 7ltr modes of flush. Works as good as any other product, easy to fit, suitable for all standard single flush lever systems. Some slightly confusing instructions (says certain parts are not included, but they were).

Rated 5 out of 5 by from Great Product Bought a few of these now, they are straight forward to fit and haven't had to replace one yet in our busy facility where everything is heavily used. Would recommend

Fitted this recently. Flushes very little water. Barely takes away solids at times. There are 3 red buttons on the assembly. Do they change the water amount flushed and how do I change settings in situ?

Also my wife, who has arthritis in her hands, finds it nearly impossible to flush. It really is very stiff. Any hints please?
Asked by: Needawin
Not sure that this is a Dudley Product that has been fitted? We do not use red buttons on our syphons, on the S7 Cascade we use a white plug, and a yellow flap to control flush volumes. If you need anything else please contact us at sales@tyde.co.uk Kindest Regards Thomas Dudley Sales Team

Will this fit a Armitage Shanks Cottage Close-Coupled Toilet

Asked by: l100

Hi, would this siphon be a good replacement for a Thomas dudley hi flo S9B

Asked by: Westian1
Hi. No, we do still sell the Hi Flo syphon or another good replacement would be the Turbo 44 syphon (neither of these are stocked at Screwfix though) regards, Georgina

Can this be used to replace a 20+ years old S7B?

Asked by: doityourself1
Yes, it is the same size. The B means it has a boss to locate the lid screw. regards, Georgina

does New Thomas Dudley Ltd THOMAS DUDLEY LTD S7 CASCADE SIPHON 8" (7510F) have an internal overflow

What is the difference between this model and the model cat ref 8121f
Asked by: yop1
Good afternoon Yop1... I can confirm that the 8" S7 Cascade Syphon has a internal overflow. With regards to the difference the Cascade 7510F is a 8" Syphon and the Cascade 8121F is a 9" Syphon... there was a misprint on the website which was a mistake of Thomas Dudley Ltd and not Screwfix... Thank you once again for choosing Thomas Dudley as your choice of Syphons and thank you for bringing the above to our attention... As always if you have any further questions please feel free to let us know... Happy plumbing and kind regards, Chris Marsh - Thomas Dudley Ltd.
