How to document an under-sink leak

Empty the cabinet only when safe, then track whether moisture begins at a supply, faucet, drain, disposal, or basin.

THE SHORT ANSWER

Answer

Empty the cabinet only when safe, then track whether moisture begins at a supply, faucet, drain, disposal, or basin.

Water can follow hoses and surfaces, so the lowest wet spot may not be the origin.

Guide

PART01

Empty the cabinet carefully

Move ordinary stored items only when the area is dry enough to enter and no outlet, disposal, or appliance connection is wet. Place removed items where leakage cannot spread. Do not disconnect bottles, filters, hoses, traps, or valves to improve visibility.

PART02

Find the highest visible moisture

Check the faucet base, spray hose, supply connections, shutoffs, basin, drain, disposal, dishwasher line, and cabinet walls. Water can follow a component before dropping. Photograph the first wet point you can see rather than assuming the puddle marks the origin.

PART03

Match moisture to ordinary use

Note whether water appears with the faucet off, during hot or cold flow, while the sink drains, when a disposal runs, or during a dishwasher cycle. Do not repeat a cycle near wet electrical equipment. One safe observation is enough for the call.

PART04

Cabinet repair is another decision

Swollen shelving, loose laminate, stained flooring, or damp drywall can remain after the plumbing leak stops. Ask who evaluates drying and materials, and whether cabinet removal is needed for access. Keep restoration outside the plumbing scope unless it is written in.

PART05

Leave a dry baseline after repair

Once the included work is complete, photograph accessible connections and the cabinet under a normal-use check. Record which fixture and appliance routes were tested. An excluded disposal, dishwasher, finish, or hidden area should remain on the closeout list.

COMMON QUESTIONS

Questions

What should I describe first?

Describe a drop, spray, wet fitting, damp cabinet, swollen panel, or puddle below a sink. Add photos before wiping, the highest visible wet point, fixture use timing, and any appliance connection. That gives the recipient a clearer starting point.

When should I stop checking?

Before checking anything else, avoid wet outlets and do not run water merely to recreate a leak that could cause more damage. Water can follow hoses and surfaces, so the lowest wet spot may not be the origin.

What should the call decide?

Ask which component needs testing and whether cabinet or finish damage belongs in a separate scope. Prepare stored items moved to a dry place and clear access to existing valves and connections only where doing so remains safe, relevant, and authorized.
