Community Tips
Standing water or soft spots in cabinet flooring indicate active leaks from supply lines or P-traps, which can compromise structural integrity and create mold within 48 hours if left unaddressed. Immediate action is required even if dripping has stopped.
Check P-trap seals by running water and observing for moisture at compression fittings; hand-tightening often stops minor weeps without replacement parts. RectorsealThread Seal Tape ($3-5) applied to male threads prevents 90% of gradual seeping issues when reassembling connections.
A Ridgid SeeSnake Micro Inspection Camera ($40-60) reveals blockages, corrosion, and hidden damage inside drain lines that a flashlight alone cannot detect, eliminating guesswork on whether replacement is necessary. This camera attaches to most smartphones and captures images for documentation. ---
