Potential Consequences of Ignoring a Leaking Sink

How to Fix a Leaking Sink

A leaking sink isn’t just an annoyance; it can lead to water damage, the growth of mold and mildew, and a skyrocketing water bill if left unchecked. The flow of your household’s day-to-day is unexpectedly disrupted by a persistent drip-drip-drip, a subtle indication of a home issue that requires prompt attention.

The Quiet Cost of Wasted Water

According to the Environmental Protection Agency, the average household’s leaks can account for nearly 10,000 gallons of wasted water each year. For a single faucet dripping per minute, that’s approximately 3,000 gallons a year.

Water-Driven Warping

Continuous exposure to water from leaks can cause damage to cabinetry, floors, and structural foundations. The financial toll of repairs can be considerably heftier than addressing the root of the leak in a timely manner.

Tracing the Source: Where Leaks Begin

A sudden spike in your water bill or the patter of tiny feet in the middle of the night could signify a sink in crisis. Before you can fix it, you need to know what’s broken.

Common Leak Types

Faucet Leaks: These are usually the result of worn-out O-rings, gaskets, or valve seats. Typically, a dripping faucet will have a leak from the base or the end of the spout.

Drain Leaks: Commonly found below the sink, drain leaks can occur from damaged gaskets or the wearing out of the plumbers’ putty.

Pipe Leaks: These could be the most troubling due to the potential for pipe corrosion or damage. They are often evidenced by water under or around the sink or water stains on the cabinetry.


Droplets Don’t Discriminate

Signs of a sink leak are varied and often subtle:

  • Warm spots on the floor could indicate a pipe underneath the sink is leaking.
  • Water staining and mold or mildew growth might be evidence of a persistent issue.
  • Musty odors in cabinets could be the tip-off to a hidden leak.
