Step 2 · Clean Faucet Aerator
The aerator is the small, screened cap on the very tip of the faucet spout. It's the most common cause of low flow. Unscrew it by turning it counter-clockwise. If it's too tight to turn by hand, wrap it with a cloth or painter's tape and use pliers to gently loosen it. Once removed, disassemble the aerator by separating the screen, washer, and housing. Use a small brush, like an old toothbrush, to scrub away any sediment or mineral deposits from the screen. For heavy buildup, soak the parts in a small bowl of white vinegar for 30 minutes, then scrub and rinse thoroughly. Reassemble the aerator and screw it back onto the faucet hand-tight.
