I've tried Drano, a plunger, and a Drain Snake. My Melbourne Drain Is Still Blocked. What's Actually Going On?
If you have tried Drano, a plunger and a drain snake and your drain is still blocked, stop. You have already done everything the internet told you to do. The drain is still not moving. That is not bad luck, and it is not a user error. What you are dealing with is beyond what any DIY tool can fix, and every extra attempt from here is either wasting time or making the actual cause harder for a plumber to sort out.
Here is what three failed DIY attempts actually tell us about what is going on inside your pipe, why the standard tools could not touch it, and what happens next.
Why Drano, Plungers and Drain Snakes Failed
Each of these tools does one specific thing. When all three fail, that combination of failures actually narrows down the cause significantly:
What You Tried | What It Actually Does | What Its Failure Tells You |
Drano (or any chemical drain cleaner) | Dissolves organic material: hair, soap scum, grease, food residue. That is the full list. | If Drano did nothing, the blockage is NOT organic. You are dealing with something solid: tree roots, a foreign object, scale, or a collapsed pipe. |
Plunger | Creates pressure to push or pull a blockage that is close to the drain opening (within 30 to 50 cm). | If the plunger moves nothing, the blockage is deeper in the line than a plunger can reach. Usually 1 metre or more down the pipe. |
Drain snake (hand-crank or hardware-store model) | Punches a small hole through a soft blockage within the first 3 to 8 metres of the pipe. | If the snake hits resistance and cannot break through, there is a solid obstruction: root mass, a collapsed pipe section, or a foreign object that the snake cannot grab. |
In short, the blockage is solid, it is deep in the line, and no hardware-store tool is going to reach it. That is not a judgment on your effort. It is a physical limit of the tools.

What Your Drain Is Probably Telling You
Read the failure pattern, and you can usually narrow the cause down to one of four things:
If Drano dissolved nothing → it is not grease or hair
Chemical drain cleaners only work on organic material. If the Drano did not budge a thing, the blockage is inorganic. That rules out the two most common causes (hair in a bathroom drain, grease in a kitchen drain) and leaves you looking at tree roots, a foreign object, scale buildup, or pipe damage.
If the plunger moved nothing → the blockage is deep
A plunger can only move a blockage it can reach. If you got zero movement, you are dealing with something at least 1 metre down the line, possibly much further. At that depth, a professional electric eel or hydrojet is the only tool that makes physical contact with the blockage.
If the drain snake hits a hard stop → it is a solid obstruction
This is the most diagnostic failure of the three. A snake getting stuck or hitting unmovable resistance tells you the blockage is not a soft mass you can push through. It is one of the following: a tree root intrusion, a collapsed section of pipe, a foreign object the snake cannot grab, or heavy mineral scale.
If all three failed → the cause is almost always one of four things
Based on the Melbourne blocked drain callouts we attend every week after homeowners have exhausted DIY, the cause is almost always:
- Tree roots inside the pipe (most common in Brunswick, Fitzroy, Richmond, Hawthorn, Northcote, and any inner-suburb home with clay pipes)
- A cracked or collapsed pipe section (common in 1970s homes across Preston, Reservoir, Bundoora, and Coburg)
- A foreign object (wet wipes, sanitary products, kids’ toys, dental floss buildup)
- Mineral scale (older galvanised waste pipes, and sometimes hot water systems, are leaking scale into the line)
Why Continuing to DIY Now Will Make It Cost More
A blockage that has already resisted three DIY attempts will not resolve on attempt four. What it will do is one of these three things:
- Damage the pipe further. A hardware-store drain snake, hitting a collapsed pipe section, keeps pushing on the damaged area. Every attempt enlarges the crack and moves it closer to a full collapse, which converts a $1,500 relining job into a $4,000+ excavation.
- Push the blockage further downstream. A half-shifted root mass or a softened wet-wipe clog that has been shoved deeper into the main line turns a simple clear into a multi-point job. What would have been $250 at the access point becomes $500+ because the plumber now has to reach further.
- Break the DIY tool off inside the pipe. This is more common than you think. Consumer-grade drain snakes snap or get stuck, and retrieval becomes its own job. We have pulled snapped snakes out of Melbourne drains more than once.
Every extra DIY attempt from the point you are at right now has a real chance of making the eventual professional fix more expensive, not cheaper.
What a Plumber Does That You Can't: The CCTV Camera Comes First
Here is the important bit that most homeowners do not realise: a professional plumber does not start with a bigger drain snake. They start with a camera.
A CCTV drain camera is a waterproof camera on a flexible cable that runs the full length of your pipe. It sends live video to a screen on the plumber’s van. You can watch it happen in real time. Within 30 minutes, you will see exactly:
- What the blockage is (roots, a crack, a foreign object, scale)
- Exactly where it is (distance from the access point, and therefore which part of the pipe)
- The condition of the rest of the line (any other damage coming in the next 6 to 12 months)
Once you know what you are dealing with, the fix is a specific tool, not a guess. A root mass gets a hydrojet. A collapsed section gets relined. A foreign object gets retrieved. Scale gets a different nozzle again. The CCTV step is what separates a plumber from someone who owns better tools than you do.
The True Cost Behind This Issue
Honest Melbourne prices for the path forward from where you are right now:
Step | Melbourne Price Range |
CCTV camera inspection (find the cause) | $250 to $450 |
Standard electric eel clear (professional drain snake) | $180 to $320 |
Hydrojetting (root mass, compacted blockage, scale) | $350 to $650 |
Pipe relining (permanent fix for cracked or collapsed pipe) | $500 to $3,000+ |
Typical total for “tried DIY, drain still blocked” in Melbourne | $400 to $750 (inspection + clear) |
A typical “I tried DIY and the drain is still blocked” job in Melbourne ends up between $400 and $750 all-in: a CCTV inspection to confirm the cause, plus either a professional electric eel clear or a hydrojet, depending on what the camera finds.
Key point: You should always get a fixed price before work starts. Ask for the inspection fee, the clear fee, and what happens if the blockage needs to be escalated to a hydrojet. All three numbers upfront.
Frequently Asked Questions
Why didn't Drano work on my blocked drain?
Drano and other chemical drain cleaners only dissolve organic material: hair, soap scum, grease, and food residue. If Drano had no effect, the blockage is not organic. That usually means tree roots, a foreign object, a collapsed pipe section, or mineral scale, and none of those can be dissolved chemically.
Why didn't a drain snake work either?
A consumer-grade drain snake is designed to punch through soft blockages within the first 3 to 8 metres of pipe. If the snake hits resistance and cannot break through, the obstruction is solid (roots, a collapsed pipe, or a wedged object), or the blockage is deeper than the snake can reach. A professional electric eel is longer, thicker, and powered, which is why it works when hand snakes fail.
Should I try a bigger drain snake from a hardware store?
Strongly recommend against it. A larger hardware-store snake can catch on a cracked pipe section and make the damage worse. It can also break off inside the pipe. The problem is not tool size; it is that you do not know what is causing the blockage. A CCTV inspection tells you that in 30 minutes, and it costs less than escalating your DIY.
Is a CCTV drain inspection really necessary?
If you have already tried three DIY methods and the drain is still blocked, yes. Without a CCTV inspection, the next attempt is still a guess. The inspection costs $250 to $450 and gives you recorded footage of the exact cause, the exact location, and the exact fix. It also becomes evidence for any insurance claim, landlord dispute, or builder warranty issue.
How much does a blocked drain cost to fix in Melbourne if DIY has failed?
Most Melbourne jobs in this category come in between $400 and $750 total: a CCTV inspection plus a professional clear (electric eel or hydrojet). If the inspection reveals a cracked or collapsed pipe, relining starts around $1,500 for a short section. A good plumber will give you all of these prices upfront after the CCTV footage, so you can decide before work starts.
Could pouring more Drano damage my Melbourne pipes?
Yes. Repeated Drano use on older galvanised or PVC pipes can corrode joints and accelerate existing damage. It is also dangerous: concentrated Drano sitting in a blocked pipe can splash back when the blockage is finally mechanically cleared. If three DIY attempts have failed, do not add a fourth. Get a plumber.
