kitchen tap water pressure

[someonelse]

Just had a new water softener installed, and a new kitchen tap. The water pressure from the cold now comes out initially at a good pressure (like a pent up burst) but immedialey tails off.

Not sure if this s due to
* the new tap
* the way the plumber installed the tap
* the new water softener
* the way the plumber installed the water softener

I'm pretty sure the right hand drinking water tap is unsoftened, whilst the new mixe tap (both hot/cold) is softened water. Befofe I call the plumber, any suggestions

Hi
Isolate the softener with the valves to rule out the softener and or tap.
Check how quick it fills a big jug before making the changes and after.
