How often should I pump?

Do additives replace pumping?

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.

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