Before they arrive
- Know your tank location and lid access; clear obstacles for the truck.
- List any symptoms: gurgling, slow drains, odors, or soggy ground.
- Gather past service records: last pump date, previous findings.
Questions to ask
- Will you measure and report sludge/scum levels?
- Can you check inlet/outlet baffles and clean the effluent filter?
- Do you recommend any repairs, and what’s the urgency?
- What maintenance changes would reduce odor or gurgling?
How to choose a provider
- Licensed and insured; ask about experience with your system type.
- Transparent pricing by tank size, access difficulty, and distance.
- Willing to provide a written report with measurements and findings.
What a good report includes
- Sludge and scum thickness; remaining working volume.
- Condition of inlet/outlet baffles and the effluent filter.
- Any suspected inflow/infiltration or evidence of backflow.
- Recommended next service window and maintenance tips.
Cost factors
- Tank size, distance to road, and lid depth (digging adds cost).
- Extra time for filter cleaning, inspections, or difficult access.
- Disposal fees in your region.
Typical costs and timing
Costs vary by tank size and region, but expect a pumping visit every 3–5 years for average households. Older systems, heavy occupancy, or frequent garbage disposal use may require shorter intervals.
Keep odors away after cleaning
- Spread showers and laundry through the week to avoid surges.
- Don’t flush wipes or pour antibacterial chemicals down drains.
- Use septic treatment tablets monthly to neutralize odor compounds.
