Sink Repair for Leaks, Damage & Plumbing Problems
Water around the sink, a leaking drain connection or a sink that isn’t working as it should? Proflow diagnoses and repairs kitchen, bathroom and utility sink problems.

A Wet Cabinet Doesn’t Always Mean the Sink Itself Is Leaking
Water around or beneath a sink can come from several places. The sink seal, drain assembly, faucet, water supply connections or nearby piping may all produce similar symptoms.
The first step is identifying the actual source rather than repairing the most obvious-looking component. Once the cause is isolated, the appropriate repair can be made.

Many Sink Problems Start Where You Can’t See Them
The cabinet beneath a sink contains several plumbing connections. A small leak at a drain fitting, trap, supply connection or fixture connection can gradually wet the cabinet and surrounding materials.
What Can We Help With?
Sink problems aren’t limited to a dripping faucet or blocked drain. The fixture and its plumbing work together as one system.
Leaks Beneath the Sink
Water appearing inside the cabinet or around plumbing connections beneath the fixture.
Leaking Sink Drain
Leakage around the drain assembly, fittings or trap when water leaves the sink.
Loose or Unstable Sink
Movement, failed sealing or mounting issues affecting the sink and surrounding counter area.
Water Around the Sink
Moisture appearing around the rim, faucet area or countertop that needs to be traced to its source.
Damaged Connections
Worn, loose or failed accessible plumbing connections associated with the sink.
Recurring Sink Issues
Problems that continue returning and may indicate that a component needs more than a temporary adjustment.
Some Sink Problems Are Actually Drain Problems
If the sink itself isn’t leaking but water drains slowly, backs up or won’t drain, the issue may be within the drainage system rather than the fixture.

Inspect
Check the sink, accessible connections and surrounding area for the source of the problem.
Diagnose
Determine whether the issue is with the fixture, drain, faucet, connection or adjacent plumbing.
Repair
Address the appropriate serviceable component or plumbing connection based on what is found.
Test
Run water and inspect the repaired area to confirm proper operation and check for leakage.
Sometimes the Better Fix Is a New Sink
Many sink plumbing problems can be repaired without replacing the fixture. But if the sink itself is damaged, deteriorated or being changed as part of a renovation, replacement may be the more practical option.

Why is there water underneath my sink?
Water beneath a sink can come from the drain assembly, trap, faucet connections, water supply connections or another nearby plumbing component. The source needs to be identified before deciding on the repair.
Can a leaking sink drain be repaired?
Many leaks involving accessible drain fittings and connections can be repaired. The appropriate solution depends on the location and condition of the components.
Do I need a new sink if mine leaks?
Not necessarily. If the leak originates from plumbing connections rather than damage to the sink itself, replacement of the fixture may not be required.
What if my sink is draining slowly?
Slow drainage can indicate a blockage or other drainage issue rather than a problem with the sink fixture itself. Drain cleaning may be the appropriate service.
