Hi,

I've got a bit of a problem with tap aerators clogging up with white particulates. I first noticed this after moving into the house 6 months ago, where there was very weak tap pressure. Eventually I figured out the aerators were clogged up, so cleaned those and thought nothing of it...

...until they kept getting clogged up again and again. 

At this stage I have to take them off and rinse them out every few days. They are full of small white particles, but I've noticed very small amount of black matter in them too. I thought it may be some form of mineral build up, so I soaked the aerators in vinegar overnight but the white particles didn't dissolve.

Any thoughts on what to do?

Cheers
