Rated 3 out of 5 by from Not perfect but functional Installed this in a deep concealed cistern, to facilitate future maintenance. When used like this the flap valve body is higher in the water and it is also necessary to shorten the 'C' link accordingly. Otherwise the flush is inconsistent due to loss of motion (sic) and the handle lever bashes the cistern lid. As previously mention it lacks rigidity when operated, so I had to bodge brace it at the top.

Rated 1 out of 5 by from Needs further improvement We bought seven of these. Only one gives half flush. The rest varies between half and full flush.Have contacted manufacturers to check fitting instructions but no improvement. We would quite like to send them back. Please advise

Rated 5 out of 5 by from Brilliant features and good value for money. The main reason I chose this product is that it's easy to change the diaphragm without completely dismantling the toilet! The old siphon was over 20 years old but the Viva Skylo fitted easily into the available space without having to modify anything. Even the C link was exactly the right size. The height of the siphon is easily adjustable, and also the amount of water in litres that the siphon discharges. The full flush/half flush feature is very handy for reducing the amount of water used when appropriate. When I opened the packet, a large washer was missing. I was told that the washer was no longer necessary when I made a quick call to the Viva helpline. The only problem I had was that the half flush worked but I couldn't get a full flush. Viva were again very helpful. It turned out that the orifice in the seat of the ball valve had worn and was delivering a much faster flow rate than normal. This was overpowering the siphon as it tried to fully empty the cistern. A new valve seat reduced the flow rate to normal and cured the problem; everything then worked as it should.

Rated 3 out of 5 by from Dual flush? Fitted easily and like the demountable function, but dual flush does not work if you select 6 litres for major flush
