Why Bathroom Faucet Issues Deserve Immediate Attention
A bathroom sink faucet is one of the most used fixtures in your home—but it often goes unnoticed until something goes wrong. Whether it’s a steady drip, reduced water pressure, or a loose handle, even minor issues can lead to water damage or costly repairs. The good news? Most problems are simple to diagnose and fix—if you know what to look for.
At Gowin Inc., we design durable bathroom faucet parts and provide expert repair guidance. Here’s a complete guide to the five most common issues—and how to resolve them like a pro.
Problem 1: Constant Dripping from the Faucet
What’s Happening:
A faucet that won’t stop dripping wastes water and increases your utility bills. Over time, it may also cause unseen damage to your cabinets and countertop.
Causes:
Worn-out faucet cartridge
Cracked or deteriorated rubber washers
Mineral deposits on the valve seat
Faulty hot water side (especially in dual-handle models)
Solution:
Shut off the water supply under the sink
Remove the handle and inspect the cartridge
Replace damaged parts with compatible models
Reassemble with plumber’s tape to prevent leaks

Problem 2: Low Water Pressure
What’s Going Wrong:
You turn on the faucet and barely get a trickle. This is frustrating, especially during busy mornings.
Common Culprits:
Mineral-clogged cartridge
Dirty or blocked aerator
Partially closed supply valve
Quick Fix:
Remove the aerator and soak in vinegar
Flush lines by removing the cartridge briefly
Confirm that valves under the sink are fully open
Pro Tip: If hard water is a recurring problem, consider installing a softening system or switching to mineral-resistant cartridges.
Problem 3: Loose Handle or Wobbly Faucet Base
What You Notice:
The handle spins loosely, or the entire faucet wobbles—this can escalate into leaks or detachment.
Likely Issues:
Loose mounting nuts under the sink
Internal screws inside the handle have come loose
Degraded internal gaskets
How to Fix It:
Use a basin wrench to tighten mounting nuts
Pop off the handle cap and tighten set screws
Inspect and replace any worn parts
Pro Tip: For stability issues at the neck or base, alignment checks and securing connections are key.
Problem 4: Rust and Corrosion on Faucet Surface
Visible Signs:
Green, white, or rusty patches can appear due to moisture and mineral reactions, affecting both aesthetics and function.
Root Causes:
Poor ventilation
Low-quality internal materials
Standing water exposure
Restoration Tips:
Clean affected areas with baking soda and vinegar paste
Replace corroded parts (especially washers, aerators)
For serious corrosion, upgrade to stainless steel or solid brass models
Maintenance Tip: Regularly dry the faucet after use and avoid harsh chemical cleaners.
Problem 5: Strange Noises When Faucet Is Running
Annoying Sounds:
Squealing, rattling, or whining noises could indicate serious plumbing issues or faulty components.
Potential Causes:
Loose or worn-out cartridge
Air trapped in water lines
Water hammer due to sudden shut-off
Pressure regulator malfunction
Best Fixes:
Replace noisy cartridge
Bleed air by running all taps for a few minutes
Install a water hammer arrestor
Consult a plumber for persistent pressure problems
Pro Tip: If noises persist, test the system with a pressure gauge or contact a plumber for a deeper inspection.
