Common Cause 1: A Clogged Aerator

One of the most common and easily fixable causes of low water pressure in kitchen faucets is a clogged aerator. The aerator is a small mesh screen that screws onto the end of the faucet spout and is designed to reduce water flow and improve its dispersion.

How does this happen? Over time, mineral deposits from hard water, as well as debris like sand and dirt, can accumulate in the aerator. This buildup restricts water flow, leading to a noticeable drop in pressure.

If the water flow appears uneven or splutter, the cause is likely related to the aerator. Unscrew the aerator from the faucet spout and soak it in a solution of vinegar and water to dissolve mineral buildup. Use a small brush or a toothpick to remove any remaining debris. Once clean, reattach and test the water pressure again.

Common Cause 2: Pipe Corrosion

Pipe corrosion is a more serious issue that can significantly impact water pressure. This is particularly common in older homes with galvanized steel or iron pipes, which are vulnerable to rust and corrosion over time. As pipes corrode from the inside out, the internal diameter narrows and the buildup of rust and scale restricts water flow through the pipes.

Pay attention for any rusty or brown color in pipes, and watch out for pinhole leaks. Because these problems are typically confined to a specific and often-hidden area, you may want to have a qualified plumber investigate.

Depending on the severity, sections of the corroded pipes may need to be replaced. In some cases, a complete repiping of the home might be necessary. If you need repiping, consider upgrading to modern piping materials like copper or PEX, which are more resistant to corrosion and have longer lifespans.

Common Cause 3: Water Supply Issues

Problems with the municipal water supply or the main water line into your home can also cause low water pressure in the kitchen faucet. These issues are usually beyond the control of the homeowner but can significantly affect water pressure.

Municipal supply issues can arise from maintenance work, broken water mains, or general water supply problems. Similarly, issues with the main water line into your home, such as leaks or blockages, can reduce water pressure.

Determine if neighbors are experiencing similar issues to confirm if it's a municipal problem. If the issue is widespread, contact your local water utility provider for information on any ongoing work or issues.
