Kitchen plumbing leaks often hide under the sink, behind the dishwasher, behind the refrigerator and inside the walls or floor near those spots. These areas have water lines or drains that are tucked out of sight, so a slow leak can go unnoticed for a long time.
A kitchen has more water connections than most people realize. Checking the usual hiding places from time to time can help you catch small leaks before they damage cabinets, floors or the unit below.
Under the Kitchen Sink
The cabinet under the sink holds several connections in a small space. These may include hot and cold supply lines, shutoff valves, the drain and trap, a garbage disposal and a dishwasher drain hose.
Look for damp spots, water stains, warped or swollen cabinet floors, rust on metal parts or a musty smell. Storing cleaning supplies in this cabinet can hide early signs, so clear it out now and then and take a look with a flashlight.
Behind and Under Appliances
Dishwashers and refrigerators with ice makers or water dispensers connect to the plumbing, often in places you cannot see. Possible trouble spots include:
- the dishwasher water supply and drain connections
- the line feeding a refrigerator ice maker or water dispenser
- the floor area under and in front of the dishwasher
- the wall behind the refrigerator
Signs of a hidden appliance leak can include a soft or lifting floor, stains along the base of cabinets or water that appears after the appliance runs. A leak near an appliance is not always a plumbing problem. Some come from the appliance itself, which may need the maker or an appliance technician.
Inside Walls, Floors and Ceilings
Supply and drain lines also run inside kitchen walls and under floors. Leaks there may show up as bubbling paint, stains on the wall or ceiling below, or a smell that does not go away.
These signs can have other causes, such as condensation or a leak from another unit. In Bronx apartment buildings, kitchens are often stacked, so water from one kitchen can show up in another. Report signs like these to the super or landlord.
Simple Steps That Can Help
Know where your kitchen shutoff valves are, and check that you can reach them. Some people use small water sensors under the sink or behind appliances to get an early alert. Look under the sink after a big cleanup or after the dishwasher runs.
If you find water, keep the area dry, stay away from wet outlets and cords, and turn off the nearby shutoff only if it is safe and easy to reach. Fixing the leak stops the water, but damaged cabinets or floors may need separate repair.
