Main Pipe and Deep Blockage Clearing in Singapore

When this may be needed

• Several fittings in the home are blocked at once.
• Waste water comes up through the floor trap when you haven't used water.
• Neighbours on the same stack report backed-up drains.
• A landed home's drains overflow at an outdoor inspection chamber.
• The blockage returns soon after every clearing.

What the team does

The technician checks which fittings are affected, whether neighbours on the same stack are affected, and where the branch pipe joins the main. If the evidence points to the main stack in an HDB block, you are advised to contact the town council. If the blockage is in your branch pipe, or in a landed home's own drainage, it is cleared with a powered snake from the nearest access point, and the price is confirmed before work starts.

Included in this price

• Inspection to locate the blockage
• Advice on whether it is your pipe or the town council's
• A confirmed quote before clearing
• Clearing private branch or landed-home pipework

Limits & price factors

Clearing HDB main sanitary stacks, which the town council maintains, pipe replacement, high-pressure jetting of public sewers and hacking floors are not included.

The price depends on where the blockage is, how far it is from an access point and what it is made of. Landed-home drainage runs and inspection chambers take longer than a flat's branch pipe.
