If you live in Boronia, Pakenham, Drouin, Warragul, Gippsland, the Yarra Ranges or the Mornington Peninsula, your septic system plays a crucial role in keeping your household wastewater flowing safely. But when it’s time for a septic tank pump out, many homeowners are tempted to try a DIY approach without realising how dangerous and costly it can be.
Before we dive deeper, here’s a quick overview of what you’ll learn.

What Exactly Is a Septic Tank Pump Out?
A septic tank pump out removes all accumulated sludge, scum and wastewater that has built up inside your tank. Over time:
- Heavy solids settle at the bottom
- Fats, oils and grease rise to the top
- The usable capacity between these layers becomes smaller
When this space becomes limited, your system struggles to treat wastewater properly.
Most Victorian homes need a pump out every 3–5 years, but properties in Gippsland, Pakenham and the Dandenong Ranges often require more frequent service due to clay soil, high rainfall or ageing systems.
Without regular pump outs, you may notice:
- Slow or gurgling drains
- Strong sewage odours
- Wet patches over the drain field
- Sewage pooling in the yard
- Backups inside the home
A proper pump out restores capacity, protects your drain field and keeps your system compliant.

Why DIY Septic Pump Outs Are Unsafe (and Illegal in Most Cases)
Many homeowners turn to online tutorials hoping to save money, but septic systems are not designed for DIY work. The risks are serious and often life-threatening.
Below are the most important reasons why DIY is never worth it.
1. Septic Tanks Contain Deadly Gases
Inside every septic tank are toxic and explosive gases, such as:
- Methane — highly flammable and suffocating
- Hydrogen sulphide — can cause instant unconsciousness
- Ammonia — triggers severe respiratory distress
These gases are invisible and, in high concentrations, may not smell at all. Opening a tank without proper ventilation or detection equipment is extremely dangerous.
Professionals use:
- Gas monitors
- Ventilation systems
- Sealed vacuum trucks
- PPE and breathing equipment
These are not tools available to the average homeowner.
2. Collapse Risks Are High in Older Victorian Tanks
Many homes across Gippsland, Warburton, Drouin and Pakenham have older concrete or steel tanks. These tanks may have:
- Rusting or cracked lids
- Weak access points
- Soil movement damage
Standing on or opening a compromised tank can cause a sudden collapse. Licensed technicians know how to locate, expose and open tanks safely without risk of injury.
3. DIY Waste Disposal Is Illegal in Victoria
EPA Victoria requires that septic waste must be:
- Pumped by a licensed liquid waste operator
- Transported in compliant vehicles
- Disposed of legally at an approved facility
Dumping or transporting waste yourself is illegal and can contaminate soil and waterways. It also carries heavy fines.
E & J Septics is fully licensed for all liquid waste transport and disposal.
4. DIY Pump Outs Commonly Cause Expensive Damage
Even if you manage to remove some wastewater, DIY attempts often result in:
- Broken baffles and filters
- Damaged inlet/outlet pipes
- Sludge is being forced into the drain field
- Tank flooding
- Soil contamination
A single mistake can cost thousands in repairs. Professionals prevent these issues entirely.
5. DIY Misses Critical Inspections
A pump out isn’t simply “sucking out water.”
Professionals inspect:
- Tank walls
- Baffles
- Sludge and scum levels
- Root intrusion
- Filter condition
- Drain field saturation
- Water levels and flow
DIY methods skip all of this, allowing hidden problems to worsen until the system fails.

Gippsland
High rainfall + water tables
→ Tanks fill and drain fields saturate faster.
Pakenham & Drouin
Clay soil
→ Slower drainage; more frequent pump outs needed.
Boronia & Yarra Ranges
Older homes + tree roots
→ Structural monitoring essential.
Mornington Peninsula
Coastal corrosion
→ Metal components fail sooner.
