FIXTURE PLUMBING / UNDER-SINK LEAK
Leaking Pipe Under Kitchen Sink
FIND THE SOURCE UNDER THE SINK.
A wet cabinet can damage stored items and cabinet material, but the visible puddle may not reveal where water started. We inspect the supply and drain connections under the sink and explain the repair needed.

UNDERSTAND THE ISSUE
Leaking Pipe Under Kitchen Sink: When To Call A Plumber
A supply leak may continue while the faucet is off; a drain joint usually becomes wet when the basin empties. The faucet base, shutoffs, flexible hoses, trap, disposal, dishwasher connection, and filter tubing can all wet the same cabinet. Dry the area only if it is safe and note which use brings the water back. Avoid placing hands near an energized disposal or wet electrical connection.

WHAT WE'LL CHECK
Your Leaking Pipe Under Kitchen Sink Options
We look for active drips at supply valves and hoses, then observe the drain path during appropriate water use. The leak source can be above the puddle if water tracks along a pipe or cabinet floor. We also check whether a loose connection is the whole issue or whether a cracked part or corroded shutoff needs replacement.
Repair A Supply Fitting Or Valve
When the leak is at a connector, shutoff, or faucet supply, the affected part can be replaced if surrounding components are suitable.
Repair The Drain Or Equipment Connection
A trap, disposal, dishwasher hose, or filter connection needs a repair matched to its own material and leak pattern.

GOOD TO KNOW
Leaking Pipe Under Kitchen Sink
Questions Answered.
Have a question about your plumbing? These answers cover what we’re often asked.
Why is water leaking under my kitchen sink from a pipe?
It may be from a pressurized supply connector, shutoff, drain trap, disposal, or appliance hose. Whether it leaks while the sink is unused or only when draining helps distinguish them.
Can I tighten the pipe myself?
A loose fitting may look simple, but overtightening can damage plastic drain parts or a valve. If water is active or the connection is unfamiliar, stop using the sink and arrange an assessment.
Does a puddle mean the cabinet needs replacement?
Not necessarily. Plumbing repair addresses the water source; drying or cabinet restoration depends on how long and how much material was wet and may be a separate service.
Should I stop using the disposal?
If the leak is near the disposal or any electrical part is wet, stop operating it and keep clear of the area until it can be checked safely.
