F’ing Septic Tanks

Even if water is running into the septic tank (not sure it is), it should be able to flow out again down out though the Drainfield if it is not saturated or plugged off.

If it can't get out the drainfield it is going to come back into the house up through the basement floor drain, etc.

Simple plumbing rule: water and debris all runs down hill.

Just have to figure out what is stopping it.
