FAQ

Common questions

Is septic repair an emergency?

Backups into the home, sewage on the ground, and alarms on pump or aerobic systems should be treated as urgent.

Can pumping fix a septic repair problem?

Pumping can stop an immediate backup and allow inspection, but it will not repair a failed drain field, crushed pipe, or damaged tank.

Who repairs septic systems?

Use a licensed septic installer, pumper, plumber with septic experience, or excavation contractor allowed by your local rules.
