What actually happens

When you call, tell us what you are seeing: slow drains, gurgling, sewage coming up in the lowest drain, a smell outside, or a wet patch in the yard. On site, the first step is usually opening the tank. The level inside shows whether the trouble is the line into the tank, the tank itself, or the drain field beyond it. You get the price for the fix before any work starts.

Common repairs

Broken or missing inlet and outlet baffles.
Cracked or unsafe lids, and risers to bring the lid to ground level.
Blocked or broken lines between the house and the tank.
