• Loose Connections: Over time, the connections between pipes can loosen, causing water to seep out.

Step-by-Step Guide to Fixing a Sink Pipe LeakStep 1: Turn Off the Water SupplyBefore you start any repairs, locate the shut-off valve under the sink and turn it clockwise to stop the water flow.

This creates a tighter seal.Step 5: Use a Pipe Clamp or Epoxy PuttyFor small cracks or holes, a pipe clamp or epoxy putty can provide a temporary fix. Follow the product instructions for best results.Step 6: Replace Damaged PipesIf the pipe is severely corroded or cracked, you may need to replace it. Measure the damaged section and purchase a matching replacement. Cut out the old pipe and install the new one using appropriate fittings.Step 7: Test Your RepairTurn the water supply back on and check for leaks. If everything looks good, you’ve successfully fixed the problem!Preventive Measures to Avoid Future Leaks
