Why Is the Water Pressure Low in My Moen Kitchen Faucet?

Moen manufactures a variety of kitchen faucets in many different styles, including two handled, one handled, pullout spout, high and low spout arcs and several various finishes. Sold online and in a variety of home retail or appliance stores, the faucets are typically sold with a limited warranty. Minor problems with the faucets, however, can often be resolved through troubleshooting, including issues with water pressure.

Some basic reasons account for why a Moen faucet may have low water pressure.

Water Valves

The first thing to check with low water pressure is the household water supply. Locate the water valves below the kitchen sink, and ensure the water valves are fully turned on (counterclockwise) to allow for full water supply to the faucet. Look for possible leaks on the water valves, and contact a plumber for assistance if the valves seem to be leaking.

Water Pressure

The household water supply pressure can affect the water pressure throughout the home. Inspect the water heater, and ensure the water supply is fully turned on and there are no obstructions to water flow. Straighten out any hoses or tubing. Note that running water through several faucets or appliances at the same time may reduce the overall water pressure in the home.


Many new faucets are designed to reduce water use for increased energy and water savings. The aerator is a small disc located on the tip of the water faucet. Unscrew it counterclockwise to remove it, which should increase the overall water flow.


Sediment entering the water supply can also cause debris to block the water flow to the faucet. Inspect the screen at the tip of the faucet, and use a small straight pin to loosen and remove any small debris that may be clogging the screen. You may also wish to soak the aerator in white vinegar to remove any mineral buildup before rinsing and reinstalling the aerator on the faucet.

Energy Policy Act

The U.S. government passed the Energy Policy Act in 1992 that placed regulations on water flow rates, which is non-negotiable, meaning that while the water pressure may seem low to the user, the reduced flow rate may simply be a matter of fact due to the federal regulations.
