Scum on kitchen sink aerator

[Elliot Roberts]

Hi,

I recently had a little flood in my kitchen coming from the kitchen sink. After some investigation, I discovered that it was coming from the aerator on the kitchen sink faucet.

The faucet is the kind that you can pull out and use as a hose. Therefore, the aerator is before the wand. But after pulling apart the aerator, I discovered black scum blocking the aerator grill (see pic).

As you can see, it's only partially blocked now with scum, but it was completely blocked yesterday, which is why the water backed up and created a flood.

Any ideas what could be causing this and how I can mitigate it?

The flex supply lines sometimes degrade and break off particles.

I like a whole-house sediment filter, even for city water, but if that is the only aerator with that junk, the flex supply lines are the main suspects. I have seen people post about that.

I guess it could be the flex line that is part of the fixture.
