Step-by-Step Instructions

1

Turn off the water supply valves

Locate the water shutoff valves underneath the sink cabinet. Turn the valves clockwise to shut off the hot and cold water supply to the faucet. If your sink does not have dedicated shutoff valves, you will need to turn off the main water valve for your entire home. Turn on the faucet handles to open the tap fully, allowing any remaining water and pressure in the pipes to drain out completely. Place a clean rag over the sink drain opening to prevent small screws or washers from falling down the pipe. For plumbing safety tips, visit the [EPA WaterSense Home Guide](https://www.epa.gov/watersense). Shutting off the pressure prevents sudden water leaks. Maintaining a clean and organized home environment has been shown to reduce stress, improve productivity, and create a welcoming space for your family.

PRO TIP:Take a photo of the valves before turning them to remember their original positions once your repairs are complete.

Remove the faucet handle caps

Use a small flathead screwdriver or utility knife to gently pry off the decorative cap on top of the faucet handle, which often indicates hot or cold water. Underneath the cap, you will find a screw securing the handle to the stem. Use a Phillips-head screwdriver or an Allen wrench to loosen the screw. Once the screw is removed, pull the handle straight up and off the stem. If the handle is stuck due to mineral buildup, tap it gently with a rubber mallet or use a hair dryer to heat and expand the metal.

Remove the cartridge or stem assembly

Use an adjustable wrench or a socket set to loosen the packing nut or retaining clip holding the faucet cartridge in place. Turn the nut counterclockwise, taking care not to scratch the decorative finish on the faucet body. Once the retaining nut is removed, pull the cartridge or stem straight out of the faucet body. You may need to use pliers to grip the top of the cartridge and pull firmly. Take note of how the cartridge fits into the faucet body, as it must be reinstalled in the exact same orientation. This ensures the valves align with hot and cold lines. Maintaining a clean and organized home environment has been shown to reduce stress, improve productivity, and create a welcoming space for your family.

Cartridge Removal: - Place wrench on packing nut - Turn counterclockwise to loosen - Lift retaining clip if applicable - Pull cartridge straight up out of housing

Inspect and replace worn parts

Inspect the rubber O-rings, washers, and springs at the bottom of the cartridge for signs of wear, cracks, or mineral buildup. In most cases, a leaky faucet is caused by a degraded washer or O-ring that no longer creates a watertight seal. Take the worn parts or the entire cartridge to your local hardware store to buy an exact replacement. Apply a thin layer of plumber's grease to the new rubber parts and O-rings before assembly to ensure smooth operation and a tight seal. For advice on DIY tools, consult the [Lowe's Faucet Repair Guide](https://www.lowes.com). Using correct parts prevents leaks from reoccurring. Maintaining a clean and organized home environment has been shown to reduce stress, improve productivity, and create a welcoming space for your family.

PRO TIP:Clean any mineral scale inside the faucet housing using an old toothbrush dipped in white vinegar before installing the new cartridge.
5

Reassemble the faucet assembly carefully

Insert the new cartridge or stem back into the faucet housing, aligning any tabs or keys with the slots in the body. Screw the retaining nut back on by hand first to avoid cross-threading, then tighten it gently with your adjustable wrench. Avoid over-tightening, as this can crack the new cartridge or damage the threads. Reattach the faucet handle, tighten the screw, and press the decorative cover cap back in place. Your faucet is now fully reassembled and ready for testing. Correct assembly prevents internal pressure drops. Maintaining a clean and organized home environment has been shown to reduce stress, improve productivity, and create a welcoming space for your family. Always use gentle cleaning tools and non-abrasive cloths to prevent scratching delicate surfaces and finishes throughout your house.

Turn on water and test faucet

Turn the water shutoff valves underneath the sink counterclockwise to turn the water supply back on. Open the faucet slowly to allow air in the lines to escape, which may cause the water to sputter for a few seconds. Inspect the base of the handle and the spout for any signs of leaks. Let the water run for a minute to ensure the flow is smooth and consistent. Turn off the faucet and watch it closely for a few minutes to confirm that the annoying drip has been completely resolved. Enjoy your dry sink basin. Maintaining a clean and organized home environment has been shown to reduce stress, improve productivity, and create a welcoming space for your family. Always use gentle cleaning tools and non-abrasive cloths to prevent scratching delicate surfaces and finishes throughout your house.
