Hi all, have recently started having pipes in the kitchen around the tap get really loud, see the video. It usually does it unprompted late in the evening g around three times and then stops, or in the morning when out upstairs toilet is refilling. Strangely too, when the noise does happen, the tap will trickle, and if you push the handle as far back as it will go, it stops! Any ideas on what it could be are appreciated, we have a plumber booked for Tuesday, hopefully nothing major
