Low water pressure at a sink turns routine tasks into a chore—and it’s rarely obvious whether you’re dealing with a clogged aerator or a bigger problem hiding inside the pipes.
The cause can range from simple debris at the faucet to corrosion deep inside older galvanized lines. Watch the short video below for a straightforward breakdown.
What Causes Low Water Pressure at a Sink?
The two most common culprits are a clogged aerator and corroded galvanized pipes. The aerator—the small fitting at the tip of the faucet—can collect mineral deposits and debris over time, restricting flow enough to make a noticeable difference. Clearing it out is often a quick fix.
If the home has older galvanized metal pipes, the problem runs deeper. Rust and corrosion build up on the interior walls of those pipes, narrowing the passage water travels through. At that point, the reduced pressure isn’t just at one faucet—it’s a system-wide issue that won’t go away on its own.
