Viva Skylo Dual Flush Syphon is rated 4.8 out of 5 by 30.
Rated 5 out of 5 by from Replacement Cistern Syphon This replaced an old '35' year syphon which was starting to struggle. It was easil to change over and so far is doing the job perfectly.

Rated 5 out of 5 by from Brilliant and great value Wanted one as an emergency, and noticed that the local Toolstation had them in stock. Great item and a very good value price, and would most certainly recommend.

Rated 4 out of 5 by from Good product, and relatively cheap. Good product, just a pain to install, have to drain the cistern down, which is difficult when old cyphyon not working. But did the job thank you.

Rated 4 out of 5 by from Toilet Flush System I ordered this on Wednesday and it was delivered on Thursday. I have not had time to fit this item yet although i have checked the contents of the parcel and it seems to be be missing a plastic washer for the underside of the water cistern (if the washer is in fact needed).

Rated 5 out of 5 by from Easy to install, Good value - works well I had to change the fill valve only but well worth the effort and cost of changing the syphon too at the same time.

Rated 5 out of 5 by from Perhaps - the best flush syphon This is my third purchase of this syphon as I have been updating the cisterns in my house. My main reason for buying this particular product is due to its height adjustment. This means it can be adjusted to avoid contact with the float valve in a narrow close coupled cistern. It also has an internal overflow which is another plus point.

Rated 5 out of 5 by from Easy to fit Easy to fit, works smoothly. Doesn't come with close coupling kit, I don't think any of them do, so worth checking if you need to replace the old one.
