Hi there, recently bought and got a plumber to install a mondella resonance collection pull down tap, but the water pressure now is like horrible. Takes about 12 seconds to fill a 500mL container, so its no where near the 6L a minute that is on the box. is there something that we can do to boost the pressure? Old tap that we had wasn't anywhere near as slow as this so I don't know if there's something in the pipes that is blocking the flow?
