Drain Smoke Testing Melbourne

Drain Smoke Testing Find the Smell at the Source

Mystery sewer smells, illegal cross-connections, breached stack vents and unseen pipe defects are exactly what drain smoke testing is built to expose. Water Serpent Plumbing uses non-toxic, odourless professional smoke machines to pressurise your sewer or stormwater system and show — visually — exactly where it is leaking, venting or cross-connected.

Smoke testing is invaluable for owners corporations, real estate vendors, councils and homeowners chasing problems that CCTV alone cannot solve.

Common Warning Signs

• Persistent sewer smell with no visible cause: a cracked stack, missing trap or breached vent is leaking sewer gas.
• Stormwater cross-connected to sewer: a major compliance issue often hidden under decades of renovations.
• Owners-corp odour complaints: multi-storey buildings need smoke testing to isolate the failing unit.
• Suspected unauthorised connections: pool overflows, downpipes or laundry tubs incorrectly connected to sewer.
• Pre-purchase peace of mind: pair with CCTV for a complete picture of drainage health.

Our Diagnostic & Repair Process

1. System isolation: we cap any open vents that should not see smoke and identify the entry inspection point.
2. Smoke introduction: professional electric smoke generators pressurise the system with safe, non-toxic vapour.
3. Visual survey: we walk the property and roof line documenting every point where smoke emerges, photographing each finding.
4. Report & recommendations: a written report shows each defect, its location and our recommended repair approach.

Equipment We Use

• Professional electric smoke machines: safe for occupied buildings, fully odourless and non-irritant.
• Inflatable plugs: to isolate sections of the system for targeted testing.
• Thermal & visual cameras: pick up faint emissions in poorly lit or external locations.

Frequently Asked Questions

Is the smoke safe for my family and pets?

Yes. We use a non-toxic, food-grade smoke that is odourless and leaves no residue. The home can be occupied during testing if necessary.

How long does a smoke test take?

A residential test usually takes 1–2 hours including setup and reporting. Multi-unit buildings can take a full day.

Will smoke testing damage my home?

No. The system is gently pressurised and there is no risk of damage to fittings, paintwork or carpets.

Do I really need a smoke test — can't a CCTV camera see everything?

CCTV sees the inside of pipework. Smoke testing reveals everything the system is connected to and any leaks above ground — the two are complementary, not alternatives.
