Perfect for use

Got this to replace ours in toilet that wouldn’t flush. Perfect for use

Does the job

Bought it to replace the old syphon, simple to fit and install, but had to cut a little bit of plastic off the top section to allow the float to move up and down easily next to it.

Best flush I’ve ever had.

Excellent product, good design, which is fully adjustable, & fairly easy to install. On the downside, if you dismiss the pun, I read the fitting instructions , these tell you not to put any sealant around the.rubber gasket, which you fit between the mechanism & the inside of the of the cistern. This resulted in me having a slight leak between the back nut & the base of the cistern, which I managed to seal with an epoxy resin sealant. I am very pleased with this product, & would not hesitate in buying another one.

Excellent Product

As a first timer fitting a syphon this was easy to fit with the instructions provided. Adjustable for any size system, I will certainly purchase again to repair any further syphons in my house.

keep your money

this (Thomas Dudley Dual flush syphon) dose not come with everything pictured so it cant be fitted.

So good i'm getting a second one!!

My old syphon had already gone through a couple of replacement parts, so took the plunge and bought one of these. Very easy to fit, and as another reviewer says, do replace the doughnut on closed coupled cisterns, in fact I would recommend a replacement coupling kit, and worth every penny. I'm just off to buy another for my sister in law's toilet.

It's got Turbo in it who could ask for more !

The old one was Kaput finally not a trickle So got one of these and fitted it myself Xcellent sealed first time (makes a change) and away we went whoosh Like the dual flush and the different volumes of water it uses too by adjusting the toggles Also the height adjustment meant it was just the right height for the cistern too Hoping not to have to replace the diaphragm anytime soon but looks a lot simpler than taking the whole close coupled toilet apart again

does what it says on the packet

straight forward to fit once adjusted to suit the replacement
