Bathroom Faucet Repair: Step-by-Step Guide

A dripping faucet is more than just an annoyance—it's a waste of water and money. Fortunately, most common faucet leaks are easy to fix with basic tools and a little guidance. This guide will walk you through the process of repairing your bathroom faucet.

🔧 Identifying Your Faucet Type

Before you begin, you need to know what type of faucet you have. The most common types include:

⚙️

Compression Faucet: Has two separate handles for hot and cold that you tighten to close.

🔘

Ball Faucet: A single handle that moves over a rounded ball-shaped cap.

🎚️

Cartridge Faucet: A single or double-handle faucet where the handle feels smooth when moved up/down or side-to-side.

💿

Ceramic Disc Faucet: A modern single-lever faucet that has a wide, cylindrical body.

🛠️ Tools and Materials Needed

Gather your tools before you start to make the job go smoothly.

Essential Toolkit

Adjustable wrench
Phillips and flathead screwdrivers
Pliers
Replacement parts (washers, O-rings, or a new cartridge)
White vinegar and a soft cloth for cleaning

💧 Step-by-Step Repair Guide

Follow these steps to stop that drip for good. We'll focus on a cartridge faucet, one of the most common types.

Turn Off the Water: Shut off the water supply using the stop valves under the sink. Turn the faucet on to drain any remaining water.

Remove the Handle: Pry off the decorative cap on the handle and remove the screw underneath. Lift the handle off.

Remove the Cartridge: Unscrew the retaining nut or clip holding the cartridge in place. Use pliers to gently pull the old cartridge straight out.

Install the New Cartridge: Insert the new cartridge, making sure it's aligned correctly. Secure it with the retaining clip or nut.

Reassemble and Test: Reattach the handle, then slowly turn the water supply back on. Check for leaks and test the faucet's operation.

Always take the old cartridge to the hardware store with you to ensure you buy an exact match for your faucet model.

If you've tried these steps and the leak persists, or if you're not comfortable performing the repair yourself, contact Plumber in a Box. Our professional plumbers can handle any faucet repair quickly and efficiently.
