    My wife wants a better tap in the kitchen, one with a single lever mixer, but everything I have read say that we need more hot water pressure.
    My house has gravity fed hot water (tanks in loft) and I measure 0.5 bar at the kitchen tap. Mains cold water is about 3 bar at the same tap.
    Is it possible to get a single-lever mixer kitchen tap for low hot water pressure & mains fed cold water systems?

    Thanks!

    No, but the cold mains will be fine on a low pressure tap.

    You will also have to balance the hot and cold supplies, a mono mixer will struggle with such a disparity between hot and cold

    Thanks. So, if it's not possible to install a single-lever mixer tap with only 0.5bar on the hot side, what are our options for boosting the water pressure? I don't want to go through the huge cost of converting our whole house hot water system to main pressure. Are there any small (super quiet) pumps that could be put under the sink? Or an accumulator tank? Or take a feed from the cold mains and heat the hot water side on demand with electricity ?
    Appreciate your thoughts please.

    Could you not fit a pressure reducer on the cold side to fix the disparity? Sure can get get ones to reduce to 1 bar

    The easiest way was the old way, 2 separate taps or a dual flow tap.

    You do get some better ones these days - one from SMEG - Pisa - which I particularly like, Franke have a few too ..... not the cheapest though but I've found there pretty good quality

    My partner is persistent in desiring a single lever mixer tap. What do you think of a Pump? Something like a Salamander iBoost pump installed under the sink on the hot feed. Is that a really bad idea?

    Adding a pump just for a single tap is a bit like using a hammer to crack a nut. A pressure reducing valve on the cold would be the easiest way but then that's reducing the cold water to a similar pressure as the hot, that and the tap type that is inherently restrictive and more suited to mains water pressure systems.

    Sometimes SWMBO has to be told that something that's wanted isn't going to work without significant changes.

    Get a low pressure tap and a pressure regulator on the cold feed.
