FAQs for O'Fallon, Illinois Owners

How often should I pump?

Most O'Fallon, Illinois households benefit from 2-4 year intervals, adjusted for occupancy, fixtures, and garbage disposal use.

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?

Small amounts are fine; heavy, repeated bleach shocks harm microbes and slow treatment. We guide dosage and safer options.
