Signs Your Septic Tank Is Full or Failing

Plain answers for Ocala and Marion County homeowners.

Short answer

Slow drains, gurgling pipes, and sewage odor usually mean the tank is full and needs pumping, which commonly costs about $275 to $500 in Ocala. If backups return within days of a pump-out, or the ground over the drainfield stays soggy, the drainfield is usually failing, and that is a bigger job.

Signs the tank is full

Sinks, tubs, and toilets drain slowly, especially more than one at once.
Gurgling sounds in the pipes.
Sewage odor near the tank or inside the house.
It has been 3 to 5 years or more since the last pump-out.

Signs the system is failing

Backups that come back soon after pumping.
Soggy or spongy ground over the drainfield when it has not rained.
Grass over the drainfield that is much greener than the rest of the yard.
Sewage surfacing in the yard.

What to do now

If sewage is backing up, stop using water and mark your request urgent.
Keep people and pets away from wet areas.
Note when the tank was last pumped. It helps the contractor diagnose it.

Backups that return within days of a pump-out, soggy ground or sewage surfacing over the drainfield, and grass over the drainfield that is greener than the rest of the yard. These usually point to the drainfield, not the tank.
