Low Water Pressure in Kitchen Sink

The Post Thumbnail

When you’re expecting a rush of water from your faucet, it can be disappointing and time-consuming if you’re only met with a trickle. Low water pressure from your spouts can make it harder to complete everyday tasks like doing the dishes and add up to a fair amount of time lost waiting for glasses to fill. You might not realize how much low water pressure was weighing you down until you experience what a rush having better water pressure can be for yourself.

What Causes Low Water Pressure In Faucets?

Clogged Aerator

To determine if a clogged aerator is a culprit behind your low water pressure, you can follow these steps:

  • Unscrew the aerator’s body from the faucet
  • Lay a towel out on the countertop and place the drain in the sink to prevent the aerator from going down the drain
  • Separate the outer housing of the aerator from the outside shell
    • Keep these pieces in order by placing them on the towel in the order you removed them. This makes it easier to reassemble later.
    • Clean each piece -an old toothbrush is a great tool for this.
    • If you notice some debris or limescale build-up, you can soak the parts in vinegar mixed with water.
  • Reassemble the aerator and put it back on the faucet
  • Test the sink to see if the water pressure is where it should be

Clogged Cartridge

To resolve a clogged cartridge:

  • Turn off the supply valves to the sink, then turn the sink on to remove any water that is left within the pipe.
  • After doing this put the sink’s stopper back in to ensure nothing accidentally goes down the drain
  • Pry off the cap that covers the faucet’s screw and undo the screw with an Allen wrench. This screw holds the faucet in place so you should now be able to lift the handle off the faucet.
  • Use pliers to loosen and remove the retaining nut that holds the cartridge in place. Some faucets may have a retaining clip to remove in addition to the nut. Place all of  these pieces on a towel
  • Lift the cartridge straight up to remove it.
  • Rinse the cartridge with water from another sink
    • If there is a lot of dirt or hard-to-remove limescale, you may need to soak it in vinegar mixed with water.
    • If the cartridge has a lot of scratches or tears, it is time to replace it.
  • Replace the cartridge and realign the tabs on the cartridge so the notices on the faucet face the opening.
  • Reassemble the rest of the faucet by putting the parts back in the reverse order that you removed them.
  • Test the sink to see if the water pressure is back to where it should be.
