Why Is My Faucet Dripping and Making Hammer Noise?
Why Is My Faucet Dripping and Making Hammer Noise?
A dripping faucet and loud hammering noise are two of the most common plumbing complaints in Singapore homes. Many homeowners notice water dripping from their basin tap, kitchen tap, or shower tap, while others hear a loud “bang” or “thud” sound when turning the tap on or off.
While these issues may seem minor at first, they can lead to higher water bills, unnecessary wear on plumbing components, and daily frustration.
At ADM Plumbing Services, we regularly help homeowners diagnose dripping taps, water hammer problems, and noisy faucets. In many cases, replacing an old or worn-out tap with a high-quality faucet can significantly improve performance and reduce noise.
What Causes a Faucet to Drip?
A dripping faucet usually indicates that one or more internal components are worn out.
Common causes include:
Worn Cartridge
Most modern mixer taps use a cartridge to control water flow.
Over time:
- Internal seals wear out
- Water bypasses the sealing surfaces
- Dripping occurs even when the tap is fully closed
Worn Rubber Seal
Older taps often contain rubber washers and seals.
These components can:
- Harden with age
- Crack over time
- Lose their ability to create a watertight seal
Mineral Build-Up
Singapore’s water supply can gradually leave deposits inside faucet components.
This build-up may:
- Affect cartridge performance
- Prevent proper sealing
- Cause slow dripping
Ageing Faucet
After years of daily use, some faucets simply reach the end of their service life.
Common signs include:
- Dripping
- Stiff handle operation
- Loose handles
- Reduced water flow
- Increased operating noise
What Is Water Hammer Noise?
Water hammer is the loud banging or knocking sound heard when water flow suddenly stops.
Many homeowners describe it as:
- “Bang”
- “Knock”
- “Thud”
- “Pipe shaking sound”
This noise often occurs when:
- Closing a faucet quickly
- Turning off a washing machine
- Stopping water flow suddenly
Why Does My Faucet Cause Hammer Sound?
Poor Faucet Design
Not all faucets control water flow smoothly.
Lower-quality taps may:
- Shut water off too abruptly
- Create sudden pressure changes
- Trigger water hammer effects
High Water Pressure
Excessive water pressure can increase hammering noises.
The higher the pressure, the stronger the shock wave when water stops flowing.
Loose Pipe Supports
When pipes are not properly secured:
- Pipes move during pressure changes
- Vibrations occur
- Hammering sounds become louder
Ageing Internal Components
Worn cartridges and internal parts can cause unstable water flow, contributing to noise problems.
Why You Should Not Ignore a Dripping Faucet
Many homeowners delay repairs because the dripping seems minor.
However, continuous dripping can result in:
Higher Water Bills
Even a slow drip wastes water over time.
Faster Component Wear
Constant leakage places stress on internal parts.
Potential Staining
Water dripping onto sinks and countertops can leave unsightly marks.
Increased Plumbing Problems
Minor leaks can eventually become larger issues.
Why Some Taps Create More Noise Than Others
The quality of a faucet plays a major role in performance.
A well-designed faucet typically offers:
- Smooth water control
- Stable cartridge operation
- Better pressure management
- Reduced vibration
- Quieter operation
Poor-quality taps often suffer from:
- Inconsistent flow control
- Internal wear
- Premature leakage
- Increased noise levels
