Your sink might have no water pressure due to several common issues, most often related to the faucet itself or the plumbing directly connected to it. The most frequent culprits are clogged aerators and clogged cartridges within the faucet.
Common Causes of Low Water Pressure in Your Sink:
-
Clogged Aerator: The aerator, located at the tip of your faucet, mixes air with the water stream. Over time, mineral deposits and debris can clog it, restricting water flow and reducing pressure.
- Solution: Unscrew the aerator, clean it thoroughly with a brush and vinegar, and then rinse and reassemble.
-
Clogged Cartridge: The cartridge, found beneath the sink handle, controls the flow of water. It can also become clogged with sediment and mineral buildup.
- Solution: Replacing the cartridge is typically the best option. Consult your faucet's manufacturer for the correct replacement part.
-
Partially Closed Shut-Off Valves: Locate the shut-off valves under your sink. Ensure they are fully open. Sometimes, they can be accidentally partially closed, restricting water flow.
-
Kinked or Damaged Water Supply Lines: Check the flexible water supply lines connecting your faucet to the shut-off valves. Kinks or damage can impede water flow.
-
Debris in the Faucet Body: If other solutions don't work, debris might have accumulated inside the faucet body itself.
-
Building-Wide or Home-Wide Water Pressure Issues: If all faucets in your home have low pressure, the problem lies outside the sink itself. Contact your water company or a plumber to investigate the main water supply.
Troubleshooting Tip: If only hot or cold water pressure is low, the issue is likely isolated to that side of the faucet or the corresponding supply line.
By addressing these potential causes, you can often restore normal water pressure to your sink. If you are uncomfortable performing these tasks yourself, it is always advisable to contact a qualified plumber.
