Fix Weak Water Pressure by Cleaning the Faucet Aerator

If one faucet in the house has gone weak while the rest are fine, don't call a plumber yet. The aerator — the little mesh cap where the water comes out — is likely clogged with sand and mineral grit.

How to do it

1. Unscrew the aerator by hand; use pliers with a rag over it if it's stuck.
2. Note the order of the little screens and washers so it goes back together right.
3. Soak the parts in white vinegar for an hour, then brush them clean.
4. Rinse, reassemble, and screw it back on hand-tight.

Water should come out strong and even. The same trick works on showerheads with removable faces, and it's worth doing once a year in Florida's sandy water.
