Installing new sewer/septic line....question
I am installing a new four inch pvc line to my septic system.
The line will be three feet in the ground, initially.
What is the best way to establish the new line with correct fall or 1/4 inch per foot and keep it from
settling off correct fall as dirt is returned, over the
I am thinking of putting a few four inch blocks under the new line.
Please suggest ways to prevent this new line from settling.
