Signs of Septic System Failure

They say the grass is always greener over the septic system but sometimes this is not a good sign. When your system starts to fail you will see the following signs:

Occasionally the distribution box will fail (D-Box). The D-Box is usually a cement box with an inlet from the septic tank and several outlets that evenly distributes the liquid septic into your leach field. Salt or other chemicals can cause the D-Box to disintegrate. We remove the old D-Box and replace it with a plastic D-Box (See Pictures Below).
