How to increase water pressure to bathroom taps

The fact of the matter is that plumbers are not consulted PRIOR to a purchase so taps are bought either on price or style alone.

I have learned to my cost in the past that even when you do offer advice prior to purchase some will still go ahead a buy the wrong thing and then try to make it all your fault when the performance is as carp as you predicted it would be. Nowadays I put it writing when peeps get to hear something they don't want to hear but choose to ignore it and we both sign it before work commences!! It gives me no pleasure whatsoever to be put in the position of being able to say "told you so".

A good plan would be to raise the level of the tank in the roof if the slope will allow it. Even 6" or 1ft will make a difference to the head of water and thus to the pressure. It is quite simple to do this provided you have a decent height available in the loft.

Its even simpler just to fit a tap that suits the OP's configuration TBH. The tap is restrictive to flow. Increasing the head isn't going to change that. Sorry to be negative.

I have looked at raising the tank in the loft, the tap minimum pressure is 1 bar. Instead I will probably end up fitting one of the assistance pumps e.g. a Grundfos UPA 15-90N Home Booster Water Pump or similar.

Will no doubt be a common problem in the future as taps get smaller, slinky and ceramic valved so I thought I may as well sort it now and as we already have a new boiler (that isn't a combi) and don't want to wait hours to wash my face. Bath is fine as the taps are suitable for low pressure. Very annoying really as both taps are from the same range and manufacturer and I am sure we checked both were suitable for low pressure....

Its not the pressure thats the problem. Its your flow rate. You undoubtedly had restrictions to your flow for the basin taps and if you can sort that out it will be cheaper than fitting a pump.

If you build up oooh say 20ft you may increase your "water pressure" to an acceptable level. 6" wont make a jot of difference and will cost you a lot more in time!
KS is right, its not a pressure problem, its a restriction problem causing a really poor flow rate. For every elbow, bend or isolation device fitted to the pipework you create friction which just adds to the problem.
Just out of interest how high above the bathroom is the cold water storage tank?
