Blocked Bathroom Basin Repairs Specialists in Small-Bore Drains

A blocked bathroom basin is almost always caused by hair, soap scum and toothpaste building up inside the pop-up waste or the small-bore trap below the vanity. Water Serpent Plumbing clears blocked basins quickly and cleanly without dismantling your vanity unit unless absolutely necessary.

For en-suites, powder rooms and older 32mm waste lines we use specialised micro-augers and compact jet heads designed for tight-radius bends — so we clear the blockage without damaging chrome traps or modern plastic pop-ups.

Common Warning Signs

🐢 Slow-emptying basin

Partial blockage in the trap or pop-up waste.

💧 Standing water in the bowl

Fully blocked trap or branch waste.

👃 Foul smell at the plughole

Biofilm and trapped hair starting to decompose.

🚰 Water leaking under the vanity

Pressure from the blockage forcing water past a loose trap connection.

⚫ Black flecks in the water

Biofilm dislodging from a poorly maintained waste — a sign it is time for a proper clean.

Our Diagnostic & Repair Process

1️⃣ Pop-up waste removal

We remove and clean the pop-up assembly which is the most common cause.

2️⃣ Trap clean

P-trap or bottle trap is removed, cleaned and refitted with new washers if needed.

3️⃣ Branch line clearing

If the blockage is further down we use micro-augers or a compact jetter on the 32–40mm waste.

4️⃣ Reassembly & test

All connections retorqued, all seals checked, full flow test before sign-off.

Frequently Asked Questions — Blocked Basins

Yes — if you're in Melbourne's outer east, the Dandenong Ranges or the Yarra Valley, we clear blocked bathroom basins same day in most cases. Call Jack direct on 0425 226 636.

We remove and clean the pop-up waste assembly — the most common cause — then remove, clean and refit the P-trap or bottle trap with new washers if needed. If the blockage is further down the line we use micro-augers or a compact jetter on the 32–40mm waste, then retorque every connection, check the seals and run a full flow test before sign-off.

Boiling water can damage plastic waste fittings and silicone seals. It also rarely clears a hair-and-soap blockage. Mechanical clearing is much more reliable.

Almost always just a clean and clear. We only recommend replacement if the trap or pop-up is corroded beyond reasonable repair.

No. We use drop sheets, contain the water and clean down after every job. Most basin jobs leave no trace.

Single-fixture clears like a bathroom basin start from around $300, and we quote a fixed price over the phone before attending — no hourly surprises and no call-out fee during business hours. Typical Melbourne blocked drain work runs $300–$750 depending on the job; see our blocked drain cost guide for the full breakdown.
