Works with high level cistern
11 Feb 2014
By john607
, Winchester
"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."

So much better than a bucket
26 Oct 2013
By crabman
, Shropshire
"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.

Screwfix by far the cheapest
8 Sep 2013
By svennerski

"I found this same unit for nearly £20 at another well known DIY store! Screwfix were £13 cheaper.
Anyway, I got this fitted fairly quickly having never done one before. Very straightforward and great value for money. Very pleased."

Easy to fit we syphon
15 Apr 2013
By JamieD
, Haywards Heath
"The Opella dual flush syphon was very easy to fit and easy to use.
The hardest part of the operation was getting the old syphon out!
This was cheap as chips and very good quality for a fiver.

efficient and reliable syphon
28 Jan 2013
By ronncarr
, n ireland
"sturdy and easy to fit. On reflection after fitting, I think for future syphon replacements on close coupled cisterns, I might use the type where syphon can be clicked off the stem to replace, thus avoiding need to dismantle the whole close coupling. But this is not a criticism of this item --- it is good value and reliable ."

opella dual flush syphon
9 Dec 2012
By mtrtravers
, honiton, devon
"bought this to replace the old syphon in an overhead cistern. bargain at a fiver and really easy to fit. i siliconed the joints just to be sure of a water tight seal and have had no problems. its only been in a month or so therefore the reliability remains to be seen. but so good so far! the dual flush is a bonus too."

Confusion over bungs - SOLVED
14 Nov 2012
By SteveJE
, London
"I was uncertain about the bungs because the instructions aren't clear, so I emailed Opella, this is their reply -
'If the hole in the picture is coloured in it means the bung is present, therefore for a full 9 litre flush both bungs need to be left in'.
Other than the confusing instructions this siphon works well and is great value for money."

"I always choose Screwfix for syphon valves.
Not only are they good, but when I have my local plumbers merchants and builders merchants chargin £10+vat for the same thing, it makes financial sense.....
not a complaint of failure either, it truely is a "fit and forget" item......"

Good replacement syphon
10 Aug 2012
By ohgrief
, Horsham
"Fitted a couple of these now without great problem. Opella could improve the drawing because I always hesitate when I set the bungs - does black blob mean bung in or out. A key would answer it all. Otherwise a brilliant replacement."
