Bought a tap 2-3 years back. Water tank started leaking. For a product which cost me over £400 plus the filter replacements costing £36 each time, I was surprised to see it fail in just over 2 years. Called them and their response was that I have to buy a brand new tank for £200 for repair the existing one for £120. I don't think it's worth investing in considering you will have to spend £200 every 2/3 years to replace the tank. Shame as the tap was decent aswell until recently where the boiling tap handle button got jammed
