Clogged Sink Repair in Singapore

Understanding the problem

A sink that empties slowly is telling you the trap or waste pipe is already half blocked. A1PlumberSG opens up the waste, clears the build-up and checks that the trap is correctly sealed when it goes back together.

Common causes

• Hair and toothpaste collecting in the bottle trap
• Grease and detergent residue coating the waste pipe
• A trap that was never fully tightened after installation
• Small objects washed into the waste outlet

Signs and symptoms

• Water sitting in the basin long after you finish
• Bubbling or gurgling as the sink empties
• Damp inside the vanity cabinet
• A sour smell around the plughole

How A1PlumberSG can help

• On-site inspection to confirm exactly where the clog is coming from
• A clear explanation of the repair options and the cost before any work starts
• Repair or replacement carried out with proper tools and quality parts
• Testing after the job so you can see the problem is genuinely resolved

Why professional repair matters

Repeated pouring of caustic cleaner into a slow sink can soften plastic traps and cause them to leak into the cabinet below. Clearing the trap properly avoids that second problem.
