Talked with a septic system installer. Here is how he told me to check the system.
1) Dig and expose a section of pipe going from the home to the tank (if you don't have a cleanout).
2)Drill a 1" hole in the pipe, and start running water from the house.
3) See if any water shoots up out of hole, if it does then you have a stopped up or damaged drain line to the tank.
If no water comes out,then drain line should be OK.
Now to next step.
4) Dig and expose septic tank lid.
5) If water is coming out, then you have, either a tank that needs pumped, OR, your leetchfield is damaged or collapsed causing water to back fill the tank to where it is too full of water, that the water has nowhere else to go. So it will either come thru the ground at the top of the tank, OR, fill your drain line going to the home.
So, tomorrow i'm sure it will be raining like it has for the past 7 months, i'm going to try this.
The installer also said, if the water can relieve itself on the ground
, and you are able to flush the toilet and run water without it gurgling, then the problem is more than likely the leechfield or equivelant to what you have.
At this point i will try anything. I'll keep everyone interested in to what i find out.
