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?

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?

Smells mean gas movement or saturationfast inspection prevents damage.

Why camera inspections?
