How to Increase Water Flow to a Faucet

If you are experiencing decreased water flow from your faucet, there may be some minor clogs within the piping that are causing the restricted flow. Before calling in a plumber and paying expensive plumbing fees, you can check the problem yourself by disconnecting the faucet and searching for minor clogs.

Removing clogs can improve water flow.
  1. Locate the shut-off valves that are connected to the faucet underneath the sink. Turn on the cold water at the faucet to make sure the shut-off valves are in working order. Repeat for hot water and turn off the valves. Look for drips in the faucet after the valves are shut off and replace valves if drips are present.

  2. Put an empty container under the faucet valve to catch any water that remains in the pipes. Turn off the main water supply to the faucet, disconnecting the drain lines if they are in the way.

  3. Disconnect the garbage disposal. Remove the disposal and set aside. Locate the main service circuit panel and disconnect the breaker if the garbage disposal is directly wired. Disconnect the disposal. Leave the wires attached and leave the disposal inside the cabinet, just off to the side.

  4. Soak the threads of the faucet nuts in penetrating oil for 15 minutes. Loosen the faucet with the basin wrench and disconnect the sink.

  5. Loosen the hardware on the faucet and open it up. Disconnect the aerator located at the end of the faucet and set aside.

  6. Locate the washerless cartridges inside the faucet body. Check to make sure they are free from debris that may be clogging the tiny holes in the cartridges. Look to see if there are flow restrictors near the cartridges which serve to decrease the amount of water flow. Check the holes in the restrictors and make sure they are free from debris.

  7. Take apart the aerator and locate the round metal or plastic disks. Place a pin into each tiny hole in the disks to unclog any debris.

  8. Place the aerator disks, washerless cartridges and flow restrictors in a container of heated white vinegar. Allow to soak overnight to loosen hard water deposits.

  9. Reassemble all pieces and reconnect the garbage disposal and the faucet. Open the shut-off valves and very slowly turn the main water supply back on. Check to see if the water flow has increased.

  10. Refer to the owner's manual that accompanied the faucet at the time of purchase to troubleshoot any other problems that may be causing poor water flow if the steps above do not help.
