Causes of Bathroom Sink Drain Leaking At Base

There are several potential causes for a bathroom sink drain to leak at the base:

Loose or Damaged Washers: The washers located at the base of the drain can become loose or damaged over time, leading to leaks.
Cracked Drain Pipe: A cracked drain pipe can allow water to seep out at the base of the sink.
Broken Putty Seal: The putty seal around the drain flange can deteriorate and break, creating a path for water to leak.
Clogged Drain: A clogged drain can cause water to back up and leak from the base of the sink.
Damaged Drain Gasket: The gasket that seals the connection between the drain and the sink can become damaged and cause leaks.

Diagnostic Techniques

To diagnose the cause of the leak, several steps can be taken:

Visual Inspection: Examine the base of the sink for any visible signs of leaks or damage.
Water Test: Run water into the sink and observe the base for any leaks. If water leaks from the base, it indicates a potential issue.
Tightening the Drain: Use a wrench to tighten the drain nut at the base of the sink. If the leak stops, it suggests a loose connection.

Repair Methods

Depending on the cause of the leak, different repair methods can be employed:

Replacing Washers: Remove the old washers and replace them with new ones that fit snugly.
Repairing Cracked Pipe: Patch the crack using a sealant or epoxy repair kit.
Applying New Putty Seal: Remove the old putty and apply a new layer around the drain flange, pressing it into place.
Clearing Clogged Drain: Use a drain cleaner or auger to remove the clog and allow water to flow freely.
Replacing Drain Gasket: Remove the old gasket and replace it with a new one that creates a tight seal.
