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.

🚰 Kitchen, Bathroom or Laundry?

Reviewed and updated July 2026.

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

Do you have a blocked sink plumber near me?

Yes — we clear blocked kitchen, bathroom and laundry sinks across Melbourne's outer east, the Dandenong Ranges and the Yarra Valley, usually same day. Call Jack direct on 0425 226 636.

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.

Why is my kitchen sink draining slowly?

A slowly draining kitchen sink almost always means fat and food residue have narrowed the waste pipe — each wash coats the pipe wall until only a trickle gets through. If other fixtures are slow too, the problem is further down the main line. A slow drain is the cheap time to fix it: clearing a narrowing pipe is quicker than clearing a fully blocked one that's backed up on a Sunday night.

What's the best way to fix a blocked kitchen sink in Melbourne?

For a mild slow drain: hot (not boiling) water with dish soap, then a plunger with the overflow blocked. Skip caustic supermarket chemicals — they damage seals and rarely shift a real blockage. If the sink still won't drain, or it keeps coming back, the clog is hardened fat deeper in the waste line and needs mechanical clearing. That's the genuinely "best way": we clear the full pipe bore same-day, test under full flow, and tell you the price before we start.

My sink is clogged and nothing works — what should I do?

If plunging and boiling water haven't shifted a clogged sink, the blockage is further down the line than home methods can reach — usually hardened fat or scale in the waste pipe. Stop using the sink (especially the dishwasher, which shares the line) and call us; we clear clogged kitchen, bathroom and laundry sinks same-day with the right mechanical gear, and test under full flow before we leave.

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.

Why does my kitchen sink keep blocking?

Because grease doesn’t leave — it coats the pipe wall a little more with every wash-up until the bore is a fraction of its size. Clearing the trap helps for a week; jetting the branch line scours it back to bare pipe so the sink stays clear.

Should I pour boiling water or caustic soda down a blocked sink?

Careful — boiling water can soften PVC joints, and caustic soda rarely fixes the cause while making the drain hazardous for whoever works on it next. Warm water and dish soap is the safe DIY ceiling; past that, it’s a job for proper equipment.
