"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."
"An excellent product and the second replacement I have purchased. The first one was 5 years old and still going strong when we moved house so it was a simple choice to buy again for the new place. Much much cheaper than anything else out there."
"Have been delaying this job for some time. The siphon was a perfect replacement and has dual flush. Depress and hold/ depress and release gives short/full flush. What a bonus. Still don't know how it works but may fit another in the ensuite, I like it so much."
"Have bought many of theses valves over the years. No frills, fairly easy to fit (once you've got the cistern off) and saves you water with dual flush actions. Will fit most cisterns, but be careful with narrow body cisterns, as won't replace round flush valves such as freeflo or metro."
"This is what u want from a part fits as it should gives u a tight seal and works as it should and for the price u pay it is well worth it if I was to do the same job again a would buy this straight away directions are very clear and u can not fit the part wrong"
