Hi Tecam,
Thanks for your comment. This has been noted and mentioned by the Hep2O team many times, as you quite rightly say there is conflicting information on the Screwfix website. Hep2O do offer a 50 year guarantee - details of which can be found on the Downloads section of Hep2O.co.uk
If you have any further questions don't hesitate to get in touch.
Thanks, Hep2O team
