"Does the job for a bargain price - Easy to fix but something worth a mention - the screw thread at the bottom of the unit is long which for most situations is handy or not a problem, but for my close coupled toilet with a shallow waste entry I needed to cut down the thread after installation because of blow back - took a little while to suss this out as I'm not a plumber but after eliminating all else this was the cause - all is now well in the toilet world."
"Saves water through dual flush function, quick to install although I did have use some jointing compound to get water tight seal. This was probably more to do with the old cistern I was installing it in than the unit itself."
"I think I have already written a review of this item. I followed the instructions as laid out on the packet. I did not believe it would work and had things like doughnut washers ready to be used. I did not need them and it went in without any problems."
"This Opella duel-flush siphon was subsequently easy to fit and adjust that others I have installed. And it’s more powerful than the original one it replaces as other reviews have said, the plus for me was the staff at the shop as it was a click and collect item, they were more than helpful, plus the tea/coffee room at the shops for plumbers is a treat well done Screwfix"
"I bought this to replace an existing one which had a torn diaphragm. It was easy to install in about half an hour and works better that the original did from new. Like the dual flush option and the fact that it has an internal overflow so will just drain down the toilet instead of through an overflow pipe."
"I was looking for a toilet part. And seen some really bad reviews for this identical siphon in many other large retail stores. So i decided to take plunge and buy from screwfix as this was the cheapest. This one is about 1" shorter than my old white siphon with added feature of half flush which is useful. Fitting was easy after slight adjustments with c-link and ball float arm then after i was pleasantly surprised to discover it works even better than my last toilet flush with added benefit of half flush.
I was nervous at first thinking it may be difficult to fit or i might get leakage and it only took me 30 minutes to complete But all in all i am happy with this product does the job i would recommend this product my advise would be take your time when fitting otherwise you might need to call a plumber!"
