kitchen tap pressure's

[Tosh]

Do kitchen taps come in different pressure rating requirements.

I've put in enough baths and taps to know they do high pressure and low pressure taps depending on the system you have but it seems all kitchen taps have a pressure requirment of 1-5 bar.

I've now installed 3 seperate sets of kitchen taps with the extendable spray hose and all 3 customers have exclaimed on the lower pressure of the hot. (all 3 sets by the way have been bought by the cust from some cheap store and didn;t even come with instructions).

I've since looked at various kitchen taps in B&Q and all require a pressure of 1-5bar. I just wondered if this is the norm or you can get taps that are 0.2-1bar for low pressure and then 1-5 for high. Obviously the cold feed will always be direct from mains water pressure anyway in a kitchen but just curious about the hot.

Many THanks

You can get low pressure ones but you shouldn't be fitting any of them as they don't comply with the water regulations.

in ireland most homes have gravity fed d h w.with this comes problems with kitchen taps. regularly people ask me to swap their taps [kitchen mixer often the hose type]and with mains pressure exceeding gravity d h w . i normally install either a balancing valve on cold and or non return on hot.tap has generally reasonable flow rate/pressure,but far from ideal.am i correct in saying the uk is all mains ,unvented,combi s .this means equal hot and cold pressures -ideal for mixers.
what type of domestic set up are u talking about where your having the issues

The trouble here is the fact that companies like B&Q are buying this sort of tap (usualy fitted with 10mm or smaller feed pipes) extremly cheaply from europe where they have been used to pressurised hot water systems for years. These taps should function perfectly well with combi boilers or unvented cylinders but will struggle with gravity hot water. one cure is to install a single impellar shower booster pump on to the hot feed from the cylinder. I realise this is not really the correct way to deal with it, so get some proper taps.

thanks for info guys, thought it was me going mad,
buffy on all systems the HW has been gravity fed with cold on mains pressure so can see the logic of it now it's black and white.

It's obviously people trying to bag a bargain.

many thanks guys
