FAQs for San Marcos, TX Owners

How often should I pump?

Most San Marcos, TX households benefit from 2-4 year intervals, adjusted for occupancy, fixtures, and garbage disposal use.

Do additives replace pumping?

Bio-boosts help flow, but only mechanical pumping removes sludge and scum.

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?

Odors signal vent, filter, or overload issues; call us for diagnostics before odors become overflows.

Why camera inspections?

Video gives proof, context, and confidenceno digging until we know what is happening inside.

Is bleach safe?

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