FAQs for Sequim, Washington Owners

How often should I pump?

Most Sequim, Washington 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?

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?

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