try along kijabe street.

while on bathroom matters, i have heared of a system called something like constant pressure for the taps/showers. You see my first floor bathrooms have very low pressure. I wish to have water gush out from them at higher pressure. any ideas..

@mmarto – What type of mixers do you have? If you have installed those lever type mixers, these require high pressure.. achieved by installing an on-line water pump.
Again on constant pressure – I think you meant balanced pressure - this just means pressure of water in cold and hot water lines must be equal, for proportionate mixing at the mixer…

@mmarto, an experienced plumber can change/alter pressure simply by replacing your entry/exit pipe sizes, not the whole plumbing works. With replacement at the exit of tank and entry of tap, this would do but only done by experienced professional plumbers who can play with the diameters to achieve this.
