FAQs for Darien, IL Owners

How often should I pump?

Most Darien, IL households benefit from 2-4 year intervals, adjusted for occupancy, fixtures, and garbage disposal use.

Do additives replace pumping?

Bio-boosts help flow, but only mechanical pumping removes sludge and scum.

Can I landscape over the field?

Light native grasses are fine, but vehicles, sheds, and deep roots will choke your drainfield.

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.
