Water pressure

We have just moved in to our new home in Atalaya Park and have an issue with water pressure. Whilst upstairs bathroom has good pressure for the sink and shower, there is only a trickle coming through my kitchen sink.

Any ideas? Or recommendations for someone to identify/fix the problem? Please!

It could be slilted most Spainish taps have a filter at the end of tap, just unscrew with a ratchet only slight pressure need clean any deposits off mess test pressure before screwing back

Thanks Alanc

Tried that but no use. Saw another post about replacing shut off valve, might have to do that.

Have the hoses buckled underneath these should only be gradually bent other than that maybe you’ve got muck stuck in the service valve to the taps not unknown in new houses

Thanks Gasgit. Ours is not a new house but you might be right about the stuck muck.
