We are in midst of building work, and the kitchen tap flow pressure has slowed right down. I assumed it was from adding extra pipes elsewhere, but builder claims not and is blaming it on the tap. He says the pressure going into the tap is fine. It is only tap in house not on water softener and in v hard water area.
im a bit reluctant to buy a whole new tap as it is £300 and otherwise seems fine. We have cleaned out the removable spray, is there anything else can do eg replacing a cartridge? Are you supposed to service taps in any way?!
