A leaky bathroom sink faucet is a common plumbing issue that can lead to water damage and increased water bills. If you're facing this problem with your American Standard bathroom sink faucet, here's a comprehensive guide to help you troubleshoot and repair the issue effectively.

Identifying the Source of the Leak

Before attempting repairs, it's crucial to identify the source of the leak. Here are some common indications:

Faucet Base Leak: Water dripping from the base of the faucet indicates a loose or damaged O-ring or cartridge.
Handle Leak: A leak around the handle suggests worn-out or damaged O-rings or washer seals.
Spout Leak: Water leaking from the spout can signify a cracked or damaged spout or a faulty aerator.
Supply Line Leak: Leaks from the supply lines connecting to the faucet indicate loose connections or worn-out washers.

Troubleshooting and Repairing the Leak

Once you've identified the source of the leak, here are the steps to resolve the issue:

Faucet Base Leak:

Replace the O-rings: Shut off the water supply, remove the handle, and replace the worn-out O-rings with new ones.
Replace the Cartridge: With the water supply off, remove the handle and retaining nut. Pull out the old cartridge and insert a new one.

Handle Leak:

Replace the O-rings: Remove the handle, and replace the old O-rings with new ones to create a tight seal.
Replace the Washer Seal: Remove the handle, remove the stem, and replace the worn-out washer seal with a new one.

Spout Leak:

Replace the Spout: Remove the aerator, unscrew the old spout, and replace it with a new one.
Clean the Aerator: Unscrew the aerator and clean any debris or mineral deposits that may have caused the leak.

Supply Line Leak:

Tighten the Connections: Use a wrench to tighten the connections between the supply lines and the faucet.
Replace the Washers: If tightening doesn't resolve the issue, replace the washers inside the supply line connections.

Tips for Preventing Future Leaks

Follow these tips to minimize the chances of future leaks:

Regularly inspect your faucet for any signs of damage or wear.
Tighten loose connections promptly.
Use a soft cloth and mild cleanser to clean the faucet and aerator to prevent mineral buildup.
If you're not comfortable making repairs yourself, call a licensed plumber for assistance.
