How to Increase Water Pressure in Kitchen Water Faucets

You're trying to rinse the dinner dishes, and the water pressure in the kitchen water faucet is too low. By no means are you alone, but it almost goes without saying, the faster you get done with the mundane task of rinsing dishes the faster you can get on to something less routine. While there are many things that can contribute to low water pressure in kitchen water faucets, there is a quick check you can make to see what's decreasing the water pressure to your kitchen faucet: a partially clogged flow restrictor or water line to the kitchen faucet.

Partially Clogged Flow Restrictor

Step 1

Either by hand or with an adjustable set of locking pliers, unscrew the flow restrictor at the end of the kitchen faucet. Remove it along with any rubber gaskets.

Step 2

Inspect the flow restrictor, which is most often an aerator or screen-like piece of metal or plastic, for clogs. Clean any clogs.

Step 3

Screw the flow restrictor and gasket back onto the kitchen faucet. Turn on the water and check the water pressure to see if it has increased.

Partially Clogged Kitchen Faucet Water Line

Step 1

Turn off the hot water valve to the kitchen sink. Turn off the cold water valve to the kitchen sink.

Step 2

Remove the internal parts to the kitchen faucet, placing them in order of removal and outside the kitchen sink. Put a bucket upside-down over the top of the kitchen sink so that it will redirect water back into the kitchen sink.

Step 3

Turn on the hot water valve to the kitchen faucet. Turn on the cold water valve to the kitchen faucet.

Step 4

Let both run for two minutes. Watch for any large debris that may clear itself from the water line, which before couldn't pass through the kitchen faucet because it was too large.

Step 5

Turn off both water valves to kitchen faucet. Reassemble kitchen faucet.

Step 6

Turn on both water valves. Turn on water at the kitchen faucet and check to see if the water pressure increased.
