"Used this product to replace an old malfunctioning siphon. Never had to fit one before, but I followed the good clear instructions printed on the back of the bag it came in and the job was successfully completed in no more than half an hour saving me a plumber call out charge. Not sure how long it will last in a well-used school toilet block, but not a lot to complain about at this price."
"Old Siphon was leaking from the bottom as the rubber washer had perished. Cheap enough and easy to fit although I did have to trim a bit off the rough edge at the top as it caught on the ball cock arm. Smeared some clear sealant on the top and bottom of the rubber washer to ensure it seals well (being an old cistern). Bought in conjunction with the close coupling kit which was also easy to fit. Job done on a Sunday morning for less than 15 quid! Thanks Screwfix for being open."
"I've given reliability five stars even though it's only just been fitted, because it's as well built as the siphon it replaced, and that lasted over ten years. It's always the diaphragm that splits, anyway, and this one is just like any other.
Like everyone says - it's easy and quick to fit, and the instructions are well written if you need them. One or two reviews mention leaks - can't understand that - all nuts and washers are perfectly good for the job.
Can't believe it's dual flush at the price. It works too. Even comes with a label to persuade your family to use it."
"I can't believe how cheap and how good is this dual flush toilet syphon. If you want value there is no need to look elsewhere. It does the job, comes with all needed fittings and instructions, and is simple to fit."
