Love the tap!
I have waited a few months to write a review as I wanted to have good use of my 4in1 tap before I reviewed it.
If you have an old fashioned, upstairs hot water tank, think carefully about whether a boiling tap is right for you. We did have some teething problems as we have an old fashioned gravitation type hot water tank upstairs and there was insufficient pressure for the normal hot water to come out at anything other than a trickle, this really made using the tap for washing up and rinsing and hand washing impossible. After much toing and froing, trying various solutions recommended by the INTU team, on his own initiative, my husband installed a supplementary pump between the hot water tank and the tap which has solved the issue, but obviously at additional cost. To be fair other makes say up front that these old fashioned tanks are not suitable, but INTU does not say that anywhere on the website or during the discussions we had with them. We did not discuss our hot water set-up before purchase, so I can't say if they would have advised us against it.
Anyway, problem solved. I love the tap and I love not having a kettle or a water filter jug taking up space on my counter!
