FAQs for Cosmopolis, Washington 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?

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?

Cameras reveal cracks, roots, and misalignments invisible from the surface, saving you from guess-and-spend repairs.

Is bleach safe?

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