Septic Symptom Checker
Septic problems rarely announce themselves clearly. Select what you are actually seeing and this will tell you honestly whether it needs attention today, in the next few weeks, or simply documenting.

Why the same symptom has different causes
A slow drain can be a clog between house and tank, a tank so full of solids it has lost working volume, a failed outlet baffle, or a field that has stopped absorbing. Those range from an inexpensive line clearing to a full field replacement, which is exactly why guessing costs money.

No. It sorts symptoms by urgency so you know how fast to act. The same symptom can come from a clogged line, a tank at capacity, failed baffles, or a drainfield that has stopped absorbing — and those have very different costs.
My tank is full to the outlet pipe. Is that a symptom?
No, that is normal operation. A septic tank is designed to hold liquid at the outlet level. What matters is the depth of the solids on the bottom and the scum on top.
Should I pump the tank to make the symptom stop?
If there is an active backup, pumping is a legitimate emergency measure. But repeatedly pumping to manage a recurring symptom is one of the most expensive mistakes in septic ownership, because it treats a drainfield problem on a schedule while the cause continues.
