How to Fix a Leaky Laundry Room Sink: Step-by-step guide to repairing your sink leak

Fixing a leaky laundry room sink is often a manageable DIY project that can save you both water and money. The steps differ depending on where the leak originates—at the faucet, the pipes, or around the sink basin itself. Start by turning off the water supply to prevent further leakage. If the leak is coming from the faucet, usually the culprit is a worn-out washer, O-ring, or faulty cartridge, which can be replaced with basic tools. For leaks under the sink, check the trap (the U-shaped pipe), supply lines, and all joints for cracks, loose connections, or worn seals. Tighten fittings with a wrench or pliers and replace any damaged parts. If you see water pooling at the base of the sink, inspect the caulking and reseal if necessary. As a designer, I find that the longevity of your laundry space—both in function and aesthetics—hinges on these foundational repairs. When planning a remodel or selecting fixtures, choosing ergonomic and durable laundry room layouts not only resolves current leaks but helps prevent future issues through thoughtful placement and integration of your plumbing solutions.

Tips 1:

Always keep a towel and a bucket nearby when working under sinks to catch any residual water. Consider replacing old plumbing fixtures with modern, water-efficient models to reduce the risk of future leaks and to upgrade the overall look of your laundry space.
