Bathroom Sink Faucet Leaking From Spout

Bathroom Sink Faucet Leaking From Spout: Causes and Solutions

A leaking bathroom sink faucet can be a frustrating and potentially costly problem. The incessant dripping can waste water and increase your utility bills. It can also damage the surrounding areas, such as the sink basin, countertop, and cabinetry. Identifying the source of the leak and addressing it promptly is crucial to prevent further damage and save money.

The spout of the faucet is a common location for leaks. Here are some of the potential causes:

Loose Spout: Over time, the spout can become loose due to vibrations or wear and tear. This can create a gap between the spout and the faucet body, allowing water to escape.
Damaged O-Rings: O-rings are small rubber seals that create a watertight connection between the spout and the faucet body. If they become worn or damaged, they can allow water to leak.
Corroded Spout: If the spout is made of metal, it can corrode over time, especially if exposed to harsh cleaning agents or hard water. Corrosion can weaken the metal and cause leaks.
Faulty Cartridge: In some faucets, the cartridge is responsible for controlling the flow of water. If the cartridge becomes damaged or worn, it can cause water to leak from the spout.

To fix a faucet spout leak, you will need some basic tools and materials:

Adjustable wrench
Allen wrench
Plumber's putty or Teflon tape
Cloth or sponge

Follow these steps to repair the leak:

Turn off the water supply: Locate the shutoff valves under the sink and turn them clockwise to close them.
Remove the aerator: Unscrew the aerator at the tip of the spout using an adjustable wrench or Allen wrench.
Loosen the spout: Use an adjustable wrench to loosen the nut that secures the spout to the faucet body.
Inspect the O-rings: Remove the spout and inspect the O-rings for any damage or wear. Replace them if necessary.
Apply plumber's putty or Teflon tape: Apply a thin layer of plumber's putty or wrap Teflon tape around the threads of the spout where it connects to the faucet body.
Reinstall the spout: Reinsert the spout and tighten the nut securely, but avoid overtightening.
Reinstall the aerator: Screw the aerator back onto the spout.
Turn on the water supply: Gradually open the shutoff valves to turn on the water supply and check for any leaks.
