When a sink starts leaking underneath, it’s often more than just a loose connection. Aging drain assemblies, improper fittings, or outdated materials can lead to slow leaks, corrosion, and recurring clogs.
We recently completed an under-sink drain replacement in Spokane where the existing setup had begun to deteriorate and showed signs of previous patchwork repairs.
What We Found
- Worn fittings
- Poor alignment
- Evidence of moisture damage at the cabinet base
- An outdated trap configuration
While it may have still been “working,” this type of setup often leads to cabinet damage, subfloor issues, or hidden mold growth if ignored.
The Solution
We removed the old assembly and installed a new, properly aligned drain setup with secure, serviceable connections, including:
- A correctly positioned P-trap
- New tubular drain components
- Updated fittings tied cleanly into the existing drain line
- Leak-free, code-compliant connections
The result is a clean drain system that will perform reliably and be easy to maintain in the future.
Why Proper Drain Installation Matters
Under-sink plumbing might look simple, but incorrect pitch, improper fittings, or over-tightened connections can cause:
- Slow drainage
- Recurring clogs
- Sewer gas odors
- Premature leaks
Professional installation ensures the trap is set correctly, connections are sealed properly, and everything meets local plumbing standards.
If you’re noticing moisture under your sink, corrosion on fittings, or frequent drainage issues, it’s best to address it before cabinet or flooring damage occurs.
