Rated 1 out of 5 by from Avoid At All Costs - Very Poor This is the second time I have fitted this product - the previous one lasted about six months before not working properly...this one was even worse. After fitting on first test the top section of the fitting (blue) had not been manufactured properly and was spitting water out of the seam so the toilet wouldn't flush. With the help of super glue I resolved this and it worked fine. It operated well for exactly seven days before the flush stopped totally. On removal this was because the transparent perspex at the bottom - used in the flush mechanism had come away rendering it useless. I would seriously advise everyone to buy a more expensive product - as this has wasted several hours of my time. I also think Screwfix should stop selling products of such poor quality. I replaced it with a Thomas Dudley Siphon which is much better quality and is working fine.

Rated 5 out of 5 by from Bargin Bargin priced duel flush siphon. Easy to change and does the job perfectly every time. Got an old loo and need parts then get this. Saves on the price of a new loo for the sake of a dodgy flush. Money saver.

Rated 5 out of 5 by from OPELLA DUAL-FLUSH SIPHON Spot on. I'm no plumber and this took an hour to fit with taking the cistern completely off and cleaning it and only 5 minutes on click & collect.
