Water is leaking from under my kitchen sink. Started yesterday, getting worse. There's a small puddle forming on the floor each morning. I can hear a slow drip when the tap is off.
What's happening
The symptoms indicate a failing P-trap seal or loose compression fitting on the drain assembly beneath your kitchen sink. The slow drip when the tap is off suggests the leak is on the drain side rather than the supply line — likely where the tailpiece connects to the P-trap. Water is pooling overnight because residual water in the trap is seeping through the degraded washer. Left unaddressed for more than a few days, this can cause subfloor water damage and potential mold growth in the cabinet interior.
Why you need a pro
While P-trap replacement is sometimes DIY-able, the combination of active leaking, potential subfloor moisture, and the need to assess whether the drain pipe or garbage disposal connection is also compromised makes this a job for a licensed plumber. A professional can also check for water damage behind the cabinet that isn't visible.
