💡 Quick answer: A blocked stormwater drain shows up as pooling water, overflowing gutters or a flooded garage when it rains. We jet stormwater lines clear with a 5000 PSI jetter, remove silt, leaf and root build-up, then camera-check the pipe — same day across Melbourne's east, with the price agreed upfront before work starts. Garden hoses and hardware-store rods rarely shift compacted silt and roots. Call 0425 226 636.

Blocked Stormwater Drain Specialists Protect Your Property from Flooding

A blocked stormwater drain in a Melbourne winter is a fast path to flooded yards, undermined slabs, water damage to garages and saturated subfloors. Water Serpent Plumbing clears blocked stormwater systems, repairs collapsed pits, replaces broken aggie lines and installs new stormwater pits and grates across the eastern suburbs.

Whether your problem is silted pits, leaf-clogged downpipes, tree roots in the underground line, or stormwater discharging where it should not — we diagnose, document and fix it properly the first time.

🍂 Why Stormwater Drains Block in Melbourne's East

The same things that make the eastern suburbs and Dandenong Ranges beautiful are what block their stormwater systems. Autumn drops a huge leaf load into gutters and pits, heavy clay soil washes silt into pipes with every storm, and thirsty roots from established gums chase the water inside stormwater lines. Add the older homes still running undersized or original agricultural-pipe systems, and one summer downpour is all it takes to find the weak point.

The pattern we see every year: a line that coped fine in light rain suddenly overflows in a storm. That line was already partially blocked — the storm just exposed it. Booking a clear before winter (or a stormwater health check) is far cheaper than dealing with a flooded garage. Our guide to preparing stormwater drains for winter covers what you can do yourself.

Common Warning Signs

💧 Water pooling in the yard after rain

A blocked or broken stormwater line is the most common cause.

🌧️ Downpipes overflowing during a storm

The underground pipe cannot keep up — usually a partial blockage.

🧱 Wet patches near the slab

Subsurface leakage from a broken stormwater line, often from tree roots or ground movement.

🪨 Silted or rusted pits

Old steel grates and concrete pits collapse over time and slow flow dramatically.

🏠 Water entering the garage or under the house

Stormwater discharging in the wrong place — a serious risk to footings.

Our Diagnostic & Repair Process

1️⃣ Site survey

We trace your stormwater layout from downpipes, surface pits, drain points and the legal point of discharge.

2️⃣ Pit & grate inspection

Silted pits are cleaned out and inspected for cracks or collapse.

3️⃣ CCTV survey of the underground line

We film and locate any defects, with depth and distance recorded — see our CCTV drain inspection service.

4️⃣ Clear, repair or reline

Mechanical clearing for silt, jetting for roots, excavation or relining for breaks.

5️⃣ Discharge check

We confirm legal point of discharge and compliance with council requirements.

Frequently Asked Questions — Stormwater Drains

Yes — we clear blocked stormwater pits, grates and aggie lines across Melbourne's outer east, the Dandenong Ranges and the Yarra Valley. Demand spikes after summer storms, so if heavy rain is forecast, call Jack early on 0425 226 636.

Clearing blocked stormwater drains properly is a four-step job. First we find where the system is failing — overflowing pits, surcharging downpipes or pooling water tell us which line is blocked. Second, we clear the pits and grates of leaves, silt and debris by hand or vacuum. Third, we jet the underground line with the 5000 PSI water jetter, cutting out roots and flushing compacted silt back to the pit. Finally we run the CCTV camera through to confirm the line is clear end-to-end and check for cracks or collapsed sections that would block it again. Garden-hose flushing and hardware-store rods rarely shift a real stormwater blockage — compacted silt and roots need jetting.

Sudden damage from storm events is often covered. We provide written reports and CCTV footage that meet insurer requirements.

Yes. A CCTV survey of the stormwater line plus a check of pits, falls and the discharge point will identify the cause. We then quote a fix in writing.

Yes — we install pits and grates, replace collapsed sections, and connect to legal discharge points in full compliance with council and AS/NZS 3500.3.

Yes. All works comply with current Victorian plumbing standards and we lodge required certifications.

A stormwater line that only overflows in heavy rain is already partially blocked — leaves, silt or tree roots have narrowed the pipe so it can't carry storm flow. It will keep getting worse with every wet week. Jetting the line clear and camera-checking it restores full capacity and shows whether roots or pipe damage caused the build-up.

Everything on your property out to the legal point of discharge — pits, downpipes and private stormwater lines — is the owner's responsibility. Street drains, kerb and channel, and easement mains belong to the council. If it's unclear which side the blockage is on, a CCTV inspection pinpoints it and gives you proof to hand the council if it's theirs.

Yes — stormwater lines are a favourite target because they hold moisture year-round. Roots enter through joints and hairline cracks, then trap leaves and silt behind them until the line blocks completely. We cut the roots out with a jetter, then show you the entry point on camera so you can decide between ongoing maintenance and a permanent repair.
