"Yes, I too have managed to fit this project as a replacement for the one that had been deteriorated by the 'blue' stuff. Well, that's what my next door neighbour told me........and he knows a thing or two. Great product - works perfectly; really good value."
"Bought this to replace a similar cistern which was not dual flush. Chose this one because it said it works with a high level cistern with a pull chain. At first sight it looked identical to my old one, but it turns out that the dual flush is achieved with grooves in the centre shaft that let air in to stop the flow if you hold the chain down while flushing. For a full flush you pull and let go as usual, then the grooves are submerged. Cunning! Works very well, easy to install. The old one has been working perfectly for 12 yrs, so assume this will be as good."
"I delayed repair for a long time because I had to remove a lot of wood paneling to get to the cistern,(poor design I know) hence the Victorian method of bucket flush for a long period. The Opella was easy to fit, no leakage, and everything was included to complete fitting. The dual flush works really well, reliability will be tested with time but at present everyone is happy. At less than a fiver you can't go wrong and it's made (I think) in Britain. Well done again Screwfix."
