We've covered several topics so far from big outdoor issues to indoor items, but some of the most vulnerable spots are the small ones you don't think about or even see. When was the last time you opened up the cabinet under your sink and took a close look at the plumbing?
Kitchen and bathroom sink cabinets are dark, enclosed spaces where small issues can easily go unnoticed until they turn into water damage or mold growth.
What to look for during a quick under-sink check:
Checking the supply lines: Inspect the water supply hoses running from the wall to the faucet. Look for any signs of bulging, mineral buildup, or moisture on the exterior.
Inspecting the P-trap: Look at the curved PVC pipe underneath the sink. Check for slow leaks, loose fittings, or minor drips that might be pooling onto the cabinet floor. You might have items directly under it or in front of the space that could be concealing existing damage.
Catching a slow drip or a corroded fitting early means a simple wrench tightening or a cheap replacement part. Letting it go unchecked can lead to ruined cabinet wood, subfloor rot, and mold growth.
