Before embarking on this repair adventure, gather the necessary tools: an adjustable wrench, a hex wrench, a screwdriver, a replacement aerator (if needed), and a pair of pliers. With these tools in hand, let’s delve into the intricacies of fixing a dripping Moen kitchen faucet.

Understanding Single-Handle Moen Kitchen Faucets

Single-handle Moen kitchen faucets offer convenience and ease of use, combining hot and cold water with a single lever. Inside, the cartridge is the heart of the faucet, regulating water flow and mixing hot and cold water. If the cartridge becomes worn or damaged, it can cause the faucet to drip.

The aerator, located at the tip of the faucet, plays a crucial role in reducing water flow and providing a smooth, aerated stream. Over time, minerals and debris can clog the aerator, reducing water pressure and potentially causing the faucet to drip.

Step-by-Step Repair Guide

  1. Turn off the water supply: Locate the shut-off valves under the sink and turn them off to stop water flow to the faucet.
  2. Remove the handle: Use an adjustable wrench to loosen the set screw under the handle and lift the handle off the stem.
  3. Remove the retaining nut: Below the handle, use an adjustable wrench to loosen the large nut that holds the cartridge in place.
  4. Extract the old cartridge: Grip the cartridge with pliers and gently pull it straight up to remove it.
  5. Install the new cartridge: Insert the new cartridge into the opening and press down firmly until it seats properly.
  6. Tighten the retaining nut: Use the adjustable wrench to tighten the retaining nut securely.
  7. Reattach the handle: Place the handle over the stem and tighten the set screw using an adjustable wrench.
  8. Turn on the water supply: Slowly open the shut-off valves to restore water flow to the faucet.

Tips and Expert Advice

Inspect the aerator: Unscrew the aerator from the faucet and check if it’s clogged with minerals or debris. If so, clean it or replace it with a new one.

Replace the O-rings: O-rings are small rubber gaskets that create a watertight seal inside the faucet. Over time, O-rings can deteriorate and cause leaks. Replacing them is an effective way to stop drips.

Lubricate the moving parts: Use a silicone-based lubricant to apply a thin layer to the O-rings and other moving parts to prevent friction and wear.

Tighten loose connections: Use an adjustable wrench to check and tighten any loose connections around the faucet, including the supply lines and the base of the faucet.
