Very good apart from... The little blue stoppers that regulate the flush volume popped out after a few weeks use in two previous units we purchased. I suggest you stick them in with Fernox LS or similar before installation. Otherwise a good product. 16 Jan 2015
Job done Toilet would not flush due to a torn flap valve. I looked for a new flap valve then found the complete siphon for £4.89. Why buy a flap valve when you can get the complete siphon for this price ? I've never fitted one before but it was straightforward. It has the bonus of giving a short or long flush which the previous one did not have. At this price you can't go wrong. I've bought a second siphon to keep in reserve for the other toilet. 8 Jan 2015
Great value siphon Got this as a spare before attempting to replace toilet siphon valve and ended up using it. The siphon works well, just as you would expect, with the bonus of the half/full flush feature that wasn't on my original siphon. - Depress handle and hold down for half flush, and depress and release for full flush. The height of this siphon is about 1" lower than my original one so it flushes easier and can be set with lower water level in the cistern, so uses a little less water on every flush than previous one. I will be getting another one of these dual flush siphons soon for a high level cistern with traditional chain pull. 1 Jan 2015
