Why Is the Pipe Under My Sink Leaking? Common Causes for Seattle Homes
If you’re living in Seattle, Washington, a leaking pipe under the sink can feel like a regular household headache, especially with the city’s rainy climate adding extra moisture to your home. Whether you’re in a sleek downtown apartment or a cozy house in Ballard, pipe leaks can sneak up on you. Let’s explore some common reasons your sink’s pipe might be leaking and what you can do about it.
Loose or Worn Out Joints
Seattle’s often chilly and damp environment can take a toll on your plumbing. The joints connecting your pipes may loosen or wear out over time, causing small leaks. Temperature fluctuations can cause materials like PVC or metal to expand and contract, weakening the joints. If you're noticing a drip, check the connections first. Sometimes tightening them with a wrench will stop the leak.
Clogged Drains Leading to Pressure Build-Up
With all the coffee grounds and food scraps that make their way down Seattle sinks, clogs aren’t uncommon. When a sink drain clogs, it can increase pressure in the pipes, eventually leading to leaks. Grease, food particles, and even bits of Seattle's famous seafood dinners can contribute to these blockages. Regular drain cleaning can prevent this issue.
Corrosion of Metal Pipes
Seattle’s water quality is generally good, but older homes, especially those built in neighborhoods like Capitol Hill or Queen Anne, may still have galvanized steel or copper pipes. Over time, these metal pipes can corrode, leading to leaks. Corrosion is common in Seattle due to the area's humidity and damp climate, causing rust and weakening pipes. If this occurs you will likely need to repipe the affected line.
Garbage Disposal Leaks
In many Seattle homes, especially in modern apartments or houses, garbage disposals are a standard kitchen feature. Sometimes, it’s not the pipe under the sink leaking but the garbage disposal itself. Over time, wear and tear on the disposal unit can lead to cracks or loosened seals.
Common causes of garbage disposal leaks include:
Worn-out gaskets: These are seals between the disposal and the sink flange that can wear out or degrade, especially in moist climates like Seattle’s.
Loose connections: The mounting assembly or hose connections can loosen over time, especially with heavy use.
Cracks in the unit: If the disposal is old, cracks in the body can lead to leaks.
If you suspect the garbage disposal is leaking, check the area where the unit connects to the sink and the plumbing underneath. Replacing gaskets or tightening connections can help, but if the disposal is cracked, a disposal replacement might be necessary.
Poor Installation or DIY Plumbing
Seattle is a hub for DIY enthusiasts, but if you’ve recently installed new plumbing fixtures under your sink without professional help, there could be mistakes. Poor installation, such as improper sealing of joints or using the wrong materials, can lead to slow leaks that worsen over time.
What Can You Do About It?
Regular Maintenance: Keep an eye on your pipes, especially in Seattle’s older homes where plumbing systems may be aging.
Call a Professional: If you’re unsure, it’s best to call a local Seattle plumber to diagnose and fix the leak. Putting a bucket under the leak until a professional arrives can help reduce damage, but if possible try to avoid using the affected sink.
Replace Old Pipes: If you’re living in one of Seattle’s historic homes, consider updating old metal pipes to newer materials like PVC or PEX.
Final Thoughts
A leaking pipe under your sink might seem like a small issue, but in Seattle’s moist climate, it can quickly turn into a bigger problem, with water damage or mold growth. Keeping your plumbing in good shape with regular checks and professional help is essential for preventing leaks and maintaining a dry, safe home.
