Why has the pressure dropped in my new sink/Taps.

Question

I have replaced my kitchen sink and taps.I had good water pressure before hand but since replacing them the cold has dropped and the hot is trickling.Thanks x

Answer 1

clogged aerators, unscrew and flush

Answer 2

easy as a kitchen fitter i know this. you have an air lock you need to blow it back to release the pressure

Answer 3

the little screen at the end of your tap is clogged just unscrew it and clean the sand or particals and reinstall this is also called an aireator , the other probem is did the plumber turn the taps under the sink on all the way after replacing the taps

Answer 4

Check to see if you have a filter in the end of the tap , it can be just a small wire gauze thing but they usually clog up the first time the tap is used, unscrew the end of the tap and have a look.

Answer 5

Did you fit a thermostatic blending (mixing) valve to the pipework?

It could also be the taps. Some taps can work with low pressures (minimum 0.1 bar) others need 1 bar to work.

You could either increase the diameter of the pipe or, more expensively, fit taps that will work at a lower minimum pressure.

It depends on how your mains pressure is... Thames will do a free overnight pressure test. Also, how is your hot water generated - central system or point heaters?
