Viva Adjustable Dual-Flush Syphon is rated 4.5 out of 5 by 15.
Rated 5 out of 5 by from Bargain purchase I bought the Viva Dual-flush syphone by click and collect from Screwfix in Salisbury to replace the one which had failed in our dowstairs toilet.. The job instructions (I had never carried out such a replacement before ) were straightforward and clear, and I competed the job in about an hour. Most of that time was cleaning the main reservoir which had been in place for about ten years. The dual function is very welcome and easy to use. Easy job and I would certainly recommend the system.

Rated 5 out of 5 by from Best syphon I’ve used The viva gear is without doubt the best gear on the market. I quite often upgrade a new installation with the viva gear to stop me having to go back in a year or two to replace faulty parts.
