"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"
