A pump-out empties the tank, but a septic tank service checks that everything inside and around it still works. A technician looks at the lids, the inlet and outlet tees, the baffles, the vent pipe and any effluent filter, measures the sludge and scum, and tells you what is worn. Request quotes for a once-off inspection, a repair or a yearly maintenance plan, and local specialists respond directly.
What an inspection covers
A proper inspection starts at the surface and ends in the soakaway. The technician opens every lid, measures the depth of sludge and scum with a sludge judge or pole, checks the liquid level and looks at the tees and baffles that stop solids leaving the tank. They then check the outlet, the effluent filter if one is fitted, and the area over the drainage field for wet patches or roots.
Expect a short written report with photos. It helps if you also show the technician your house plan or earlier invoices.
Common repairs
- Lids: cracked or sunken lids are a safety hazard and let in water. Replacement lids and risers bring the opening back to ground level.
- Tees and baffles: a broken inlet or outlet tee lets sludge flow out to the drainage field and clog it.
- Vent pipe: a blocked or missing vent causes gurgling drains and smells in the house.
- Effluent filter: it traps fine solids before the outlet and needs rinsing once or twice a year.
- Cracks and leaks: small cracks in concrete can be sealed, but a badly leaking tank needs replacing.
If an inspection shows the tank is fine but the ground stays soggy, the cause is likely downstream. See septic tank drainage.
Maintenance plans
A maintenance plan spreads the work across the year. A typical plan includes one or two inspections, filter cleaning, a sludge reading and a reminder when a pump-out is due. Estates and body corporates often bundle a pump-out into the contract so costs are known in advance. A plan suits lodges and businesses most, because a failure in the busy season costs far more than the plan.
When the sludge reading shows the tank is more than a third full, the technician will recommend septic tank cleaning on the same visit if a truck is available.
Looking after the system between visits
Spread laundry across the week instead of washing everything in one day. Keep cooking fat, wet wipes, nappies and paint out of the drains, and use bleach and drain cleaners sparingly. Do not drive over the tank or the drainage area, and do not plant trees nearby, because roots follow water into pipes. Keep a record of every service with dates, so the next technician sees what was done.
What to include in your request
- Age and size of the tank, and the number of chambers if known
- What you have noticed: smells, slow drains or wet ground
- When the tank was last pumped or inspected
- Whether the lids are broken, buried or hard to lift
- Whether you want a once-off check or a yearly plan
