FAQs for Davenport, Washington Owners

How often should I pump?

Most Davenport, 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?

Choose shallow-rooted plants and avoid trees or heavy beds; compaction and roots are the enemy of percolation.

What if I smell odors?

Smells mean gas movement or saturationfast inspection prevents damage.

Why camera inspections?

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

Is bleach safe?
