Blocked Sink Plumber Melbourne

Blocked Kitchen & Laundry Sink Repairs Fast, Clean, Guaranteed

Blocked kitchen and laundry sinks are one of the most common call-outs we attend. The vast majority are caused by fats, oils and grease (FOG) congealing inside the trap or the branch waste line. Water Serpent Plumbing clears blocked sinks the same day, with mini-jetters that scour the pipe wall back to bare PVC or copper.

For laundry sinks we also check the laundry trough waste, the washing-machine standpipe, and the connection into the gully trap — the most common failure points in older Melbourne homes.

Common Warning Signs

• Standing water in the bowl: classic sign of a trap or branch-line blockage.
• Slow draining after dishwashing: partial fat build-up restricting flow.
• Gurgling when emptying the bowl: air being pulled past a partial blockage or a poorly-vented branch.
• Foul smell from the plughole: biofilm in the trap or dry trap allowing sewer gas back in.
• Laundry trough overflow when the washing machine drains: gully or main-line blockage downstream.

Our Diagnostic & Repair Process

1. Diagnosis: we check whether the issue is local to the trap or further down the waste line.
2. Trap inspection & clean: in many cases the bottle or P-trap is the issue and we clean it on the spot.
3. Mini-jet or eel the branch: we clear the branch waste line to where it joins the gully or stack.
4. Hot-water flush: final flush with hot water and degreaser to leave the line scoured.
5. Prevention advice: we leave you with practical tips to keep fats and food scraps out of the line.

Equipment We Use

• Compact electric jetters: safe for 40–80mm internal waste pipes.
• Hand augers & eels: for tight bends and short blockages near the fixture.
• Camera inspection (when needed): to confirm clearance in repeat-blockage cases.

Frequently Asked Questions

Can I use a drain cleaner from the supermarket?

We do not recommend caustic drain cleaners — they damage chrome traps and rubber seals, are dangerous on contact, and rarely clear a properly blocked line. Mechanical or hydro clearing is safer and faster.

Why does my sink keep blocking?

In Melbourne homes the usual culprits are fats and oils being washed down, food scraps, coffee grounds and old galvanised waste pipes that have scaled internally. A jet clean restores the original bore.

Do you do kitchen and laundry the same job?

Yes — if multiple fixtures are affected we clear them in one visit.

How long until the sink is usable again?

Same visit. We test the drain under full flow before we leave.
