Why Are Tiny Metal Balls Showing Up Under Your Kitchen Sink?
You’re tidying up under the kitchen sink when you spot them — small metal balls scattered around. They aren’t perfectly round, and some might even look rusty. Naturally, you ask: Where are they coming from?

A Likely Culprit: Your Pull-Out Faucet
If your kitchen sink has a pull-out or pull-down faucet, that could be the source of the mystery. These faucets usually have a retractable hose that returns smoothly thanks to a weighted mechanism.

That weight often contains tiny metal balls used to counterbalance the hose. Over time, the weight can crack, wear out, or even break open — dropping the metal balls below your sink.

How to Check Your Faucet Weight
Here’s a quick way to find out if the faucet is to blame:

Open the cabinet under your sink.

Find the hose attached to your faucet.

Look for a plastic or metal weight on the hose.

Inspect the weight for cracks, leaks, or visible damage.

If you find a damaged weight, you’ve found your answer.

Good News: It’s an Easy Fix
No need to worry. Replacing the weight is cheap and simple. Most hardware stores and online retailers sell faucet weights. Just remove the broken one and attach a new one to the hose.

What If It’s Not the Faucet?
If your faucet weight is intact, consider these other possibilities:

Dishwasher parts: If a nearby dishwasher has a broken component, it might be shedding metal beads.

Garbage disposal: Worn-out internal parts can break down and drop similar metal bits under the sink.

Prevent Future Messes
To avoid surprises, check the faucet hose and plumbing fittings under your sink every few months. Catching wear early can prevent bigger problems later.

Final Thoughts
Finding small metal balls under your kitchen sink may seem odd, but it’s usually no cause for alarm. A quick inspection often leads to a simple fix — and peace of mind.
