5 Signs Your Septic Tank Is Full

A septic tank rarely fails without warning. Knowing what to look for lets you schedule pumping on your terms instead of during an emergency.

1. Slow drains

If sinks, tubs and toilets all drain slowly at once, the tank or main line is likely backing up.

2. Gurgling pipes

Air pushed through plumbing as water tries to move is a common early signal.

3. Odors

Sewage smells near the tank or drain field mean gases are escaping where they should not.

4. Wet, lush patches

Unusually green or soggy ground over the drain field can mean effluent is surfacing.

5. Sewage backup

Water in the lowest drain of the house is the last stage. Call right away.
