In the attached image, you’ll see these brown/golden flakes that have been coming out of our tap in the kitchen (mains supply). Normally this happens when running the cold water tap at a highish pressure. In a bowl of water, you can normally see 3-4 flakes.

We’ve checked the other taps in the flat that are boiler-fed (I think), so hoping it’s just an issue with the kitchen tap.

Please could we get a quote for someone to come and take a look at this as we’re worried it could be some sort of contamination?
