How to Fix Low Water Pressure in Your Kitchen Sink?

by lefton sanitary

Is your kitchen faucet dribbling instead of gushing? Low water pressure in the kitchen sink can be a real headache, especially when you have a pile of dishes waiting to be washed. Let's dive into why this happens and how you can fix it yourself or know when it's time to call in the pros.

Reasons Behind Low Kitchen Water Pressure

Shut-off Valve Errors

Each sink has a shut-off valve that controls water flow to that fixture. If this valve is not fully open or malfunctioning, it can result in low water pressure.

Cartridge Clogs

Some kitchen faucets have a cartridge that regulates water flow. When this component gets clogged, it can lead to reduced water pressure.

Leaks

Leaks in the pipes supplying your kitchen can also cause a dip in water pressure. This issue can lead to water damage, so it’s best to address it quickly.

Aerator Clogs

One common cause of low kitchen water pressure is a clogged aerator. Over time, minerals and debris in the water supply can accumulate, restricting the water flow.

Broken Water Lines

If you’re experiencing low water pressure not just in the kitchen but throughout your house, the culprit might be a broken municipal water line. This widespread issue often affects multiple areas of your home.

 

Finding the Source of Low Water Pressure

Hot Water Only?

If only your hot water is affected, your water heater might be the issue. In this case, it’s best to call a plumber.

Isolate the Issue

Turn on each water source in your home individually. If only your kitchen faucet has low pressure, the problem is likely localized.

Check with Neighbors

If you’re experiencing low water pressure throughout your home, check with your neighbors. If they’re having the same issue, the problem could be with the municipal water supply.

Inspect for Leaks

Check under and around your kitchen sink. If you see standing water or notice any leaks, this could be the cause of your low water pressure.

Check Your Aerator

The aerator on your faucet might be clogged. Here’s how to clean it:

  • Remove the Aerator: Use pliers and a towel to unscrew the aerator.
  • Inspect for Deposits: Check the aerator for mineral buildup.
  • Test the Faucet: Run the faucet without the aerator. If the pressure is fine, you’ve found the issue.
  • Clean the Aerator: Soak it in vinegar overnight and scrub with an old toothbrush.
  • Replace the Aerator: Screw it back onto the faucet.

Check Your Faucet Cartridge

A clogged cartridge can also cause low water pressure. Follow these steps to clean or replace it:

  • Turn Off the Water: Shut off the water supply to your sink.
  • Remove the Handle: Unscrew the valve handle using an Allen wrench if necessary.
  • Lift Out the Cartridge: Remove the screws holding the cartridge in place and lift it out.
  • Inspect the Cartridge: Clean it with water and vinegar or replace it with a new one.
  • Reassemble the Faucet: Put the cartridge back and reattach the handle.
