Tiny cracks, loose tees, or clogged filters can shorten a systems life; our checklists catch them early.

Bio-augmentation is not one-size-fits-all; we dose enzymes based on load, temperature, and soil so you get gains without waste.

Our reports translate science into actions: pump frequency, landscaping dos and donts, and water-use habits that keep every shower smooth.

FAQs for Seneca, IL Owners

How often should I pump?

Interval planning depends on tank size, guest count, and water habits; we set a schedule after inspecting your system.

Do additives replace pumping?

No. Enzymes assist biology but cannot remove solids; pumping is non-negotiable for system longevity.

Can I landscape over the field?

Choose shallow-rooted plants and avoid trees or heavy beds; compaction and roots are the enemy of percolation.

What if I smell odors?

Odors signal vent, filter, or overload issues; call us for diagnostics before odors become overflows.

Why camera inspections?

Video gives proof, context, and confidenceno digging until we know what is happening inside.

Is bleach safe?

Use septic-friendly cleaners and keep harsh chemicals minimal to protect your tank biology.
