By Harper Jennings

Updated November 2026

The moen weymouth kitchen faucet is a single-handle faucet built around a clean, traditional profile, and this guide explains what it is, how to confirm it will fit your sink, and how to install and maintain one. By the end, you should know which configuration to buy, how to measure your sink holes, and how to handle the common problems owners run into, such as drips and weak flow.

What the Moen Weymouth Kitchen Faucet Is and Who It Suits

The Weymouth is part of Moen’s lineup of kitchen faucets with a single lever controlling both water temperature and flow. Its styling leans toward a classic, rounded spout and a compact body, which makes it a common choice for traditional and transitional kitchens. Because Moen offers several finishes and spout configurations under similar product families, always confirm the exact model number on the box or the faucet’s underside before you order parts or accessories.

The faucet suits homeowners who want a straightforward single-control design rather than a touchless or pot-filler setup. If you are still comparing options across brands, our overview of Best Kitchen Faucets for Style and Function: 3 Moen Models Compared places several Moen models side by side.

Check Your Sink Before You Buy

Fit is the most common reason a new faucet gets returned, so measure before purchase. Most single-hole and three-hole installations depend on the number and spacing of the holes in your countertop or sink deck.

Measure the Mounting Holes

• Count the existing holes. Faucets with a single base usually need one hole, while others need three (a center spout hole plus two handle holes).
• Measure the diameter of the spout hole. Standard faucet holes are typically 1-3/8 inches, but confirm against the manufacturer’s specification for your chosen model.
• Measure the distance from the center of the faucet to the edge of the sink basin, and check that the spout will clear the rim with room for your hands.
• Measure the deck thickness. Most faucet specifications list a maximum deck thickness, and exceeding it can prevent a proper seal.

Installing the Moen Weymouth Kitchen Faucet: Step by Step

Installation takes a few hours for most homeowners with basic tools. Read the instructions packed with your specific model first, because hose lengths and mounting hardware can vary.

Tools and Supplies You Will Need

• Adjustable wrench and basin wrench
• Plumber’s putty or a silicone gasket, depending on the faucet’s mounting design
• Flashlight and a towel or bucket
• Supply lines, if the included ones do not reach your shutoff valves
• Pliers and a screwdriver

Prepare the Work Area

1. Turn off the hot and cold shutoff valves under the sink, then run the faucet to drain remaining pressure.
2. Disconnect the old supply lines and remove the old faucet, noting how the mounting nuts and gaskets were arranged.
3. Clean the mounting surface thoroughly so the new gasket or putty seals evenly.

Mount the Faucet

1. Feed the supply lines and any hoses through the center hole.
2. Set the gasket or apply putty as the instructions specify, then position the faucet body.
3. From below, thread the mounting nut or shank and tighten it by hand before using the basin wrench. Overtightening can crack plastic components or distort the gasket.
4. Connect the supply lines to the shutoff valves, hand-tightening first, then giving each a quarter turn with a wrench.

Test for Leaks

1. Slowly open both shutoff valves.
2. Run the faucet through hot, cold and full-flow positions while watching every connection.
3. If you see drips, shut off the water and snug the connection slightly. Do not force it.

Common Problems and How to Fix Them

Most issues with a single-lever faucet like the Weymouth come down to a worn cartridge, a loose connection, or sediment in the aerator.

Dripping After Shutoff

A steady drip from the spout usually points to a worn cartridge or a damaged seat. Cartridge replacement is the usual fix. For a walkthrough, see Replace Kitchen Faucet Cartridge: Step-by-Step Repair Guide.

Low Water Pressure

Remove the aerator and check for mineral buildup or debris. Soak it in white vinegar for an hour, rinse, and reinstall. If pressure stays low across the whole house, the issue is likely the supply or a valve, not the faucet.

Leaks at the Base

Leaks under the sink or around the base often mean the mounting nut is loose or the gasket has shifted. Shut off the water, inspect the gasket, and retighten gently.

Recommended gear

• Basin wrench – Reaches the mounting nut in tight spaces under the sink, which is difficult to do with a standard wrench. View on Amazon
• Plumber’s putty – Creates a watertight seal under the faucet base when the design calls for it. View on Amazon
• Braided stainless steel supply lines – Offer more durable connections than older rubber lines, and many homeowners replace them during faucet installs. View on Amazon

Common Mistakes to Avoid

• Buying before measuring the holes and deck thickness.
• Overtightening plastic mounting nuts, which can crack them.
• Skipping the shutoff valve check and discovering a stuck valve mid-install.
• Mixing up hot and cold supply lines, which causes reversed temperature control.
• Ignoring a small drip, which can stain the sink and waste water over time.

Tips for Long-Term Care

Wipe the faucet with a soft cloth and mild soap rather than abrasive cleaners, which can dull the finish. Clean the aerator every few months if your water is hard. Check the supply line connections once a year. These small habits prevent most of the problems described above.

FAQ

Is the moen weymouth kitchen faucet a single-handle or two-handle model?

It uses a single lever to control both temperature and flow. Confirm the exact configuration on the product listing before buying.

Do I need a special tool to install it?

Most installs require only an adjustable wrench, a basin wrench, and basic hand tools. A basin wrench is strongly recommended because the mounting nut is hard to reach.

How do I know if my sink has enough holes?

Count the existing holes and compare them with the faucet’s stated requirements. Single-hole faucets need one hole, while others may require three.

Why does my faucet drip after I turn it off?

A worn cartridge or seat is the most common cause. Replacing the cartridge usually resolves it.

Can I replace the cartridge myself?

Many homeowners can, with the right tools and a careful, step-by-step approach. If you are uncomfortable working under the sink, consult a licensed plumber.

What should I do if water pressure drops suddenly?

Clean the aerator first. If the problem persists across multiple fixtures, check your home’s supply or main valve, and consult a plumber if needed.

Are replacement parts easy to find?

Parts are generally available through the manufacturer and authorized retailers. Always confirm the model number before ordering to avoid mismatches.

Conclusion

The moen weymouth kitchen faucet is a practical single-lever option for traditional kitchens, and its success depends mostly on careful measurement and a clean installation. Check your holes and deck thickness before buying, follow the included instructions for mounting, and test thoroughly for leaks. With routine cleaning and prompt attention to drips, your faucet should give years of dependable service. For specific repairs, consult a licensed plumber when a job goes beyond your comfort level.
