24/7 Emergency Drain Plumbing — Fast Response, Day or Night
Drain emergencies don't wait for business hours. A toilet overflowing at midnight, sewage backing up through the shower waste, stormwater pooling against the house in the middle of a downpour — these are the calls Water Serpent Plumbing takes 24 hours a day, 7 days a week across Melbourne's outer east.
When you call, you deal directly with Jack — the owner, and the plumber who turns up. Water Serpent is a specialist drainage business based in Kalorama, covering the Yarra Ranges, Knox and Maroondah. Because drains are the whole business, the van carries the right gear on every trip: 5000 PSI hydro jetter, CCTV drain camera and pipe locator.
No call-out fee, no after-hours surprises. There's no call-out fee within the core service area, and every job gets a fixed price quoted upfront before work starts — the number quoted is the number you pay, 2pm or 2am. And the line is genuinely 24/7: Jack answers his own phone, nights, weekends and public holidays included.
Emergency Drain Work, Around the Clock
🚨 Emergency blocked drains
Sewer or stormwater lines blocked solid, cleared with a 5000 PSI hydro jetter — see the dedicated emergency blocked drain page for what to expect.
🚽 Overflowing or blocked toilets
The most common night and weekend call, cleared same visit.
⚠️ Sewer backups
Sewage rising in showers, floor wastes or the gully gets priority response — including blocked sewer drain clearing at any hour.
🌧️ Stormwater flooding
Blocked pits and downpipe drains sending water toward the house during heavy rain.
📷 Urgent CCTV diagnosis
When a drain keeps failing, the camera finds out why on the spot — no second callout needed.
💦 Hydro jetting
Tree roots, grease and compacted debris cut out properly, not just poked through.
What Water Serpent doesn't do: hot water systems, gas fitting or roof plumbing. If your emergency is one of those, Jack will tell you straight away on the phone so you're not waiting on the wrong tradie.
What Counts as a Drain Emergency?
Not sure whether it can wait until morning? These situations shouldn't:
🚽 An overflowing toilet in a one-bathroom home
With no second toilet to fall back on, this can't wait until Monday.
🚿 Sewage backing up into the shower, bath or gully
Wastewater rising through the lowest fixtures means the sewer line is blocked — and every flush makes it worse.
🌊 Stormwater flooding toward the house
If water is banking up against walls, doors or subfloor vents in heavy rain, the stormwater system needs clearing now.
🔊 Gurgling drains and sewage smells before a storm
That's a partial blockage giving you a warning. Clearing it before the rain arrives is far cheaper than cleaning up after it.
If it genuinely can wait, Jack will say so on the phone and book a same-day or next-morning visit instead — the over-the-phone diagnosis is free either way.

1️⃣ Stop using water
Every sink, shower, washing-machine cycle and flush adds to what's already backing up.
2️⃣ Lift the overflow relief gully grate
It's the low, grated drain outside, usually near a wall. Clearing pot plants or debris off it gives sewage a safe escape point outside instead of inside your home.
3️⃣ Don't pour caustic chemicals down the drain
They rarely shift a real blockage, and they turn the pipe into a hazard for whoever works on it an hour later.
4️⃣ Keep people and pets away from any sewage
Shut the door on the affected room and leave the cleanup until the drain is cleared.
Drain Specialist vs General Plumber After Hours
Most after-hours plumbers are generalists. Called to a blocked sewer at night, they typically arrive with a plunger and a small electric eel — enough to poke a hole through the blockage and charge for the visit, with the real fix left for another day. You end up paying twice for one problem.
A drain specialist arrives with the finishing gear on the first visit. The hydro jetter cuts tree roots and scale out of the pipe rather than punching through them, and the CCTV camera confirms the line is clear and shows what caused the blockage — a one-off, or a cracked pipe that needs permanent repair. One visit, one bill, and a recorded diagnosis you keep.

| Visits & bills | You end up paying twice for one problem | One visit, one bill, recorded diagnosis you keep |
