Perhaps you can help me.
I have a 50 year old home with a septic just as old in Louisville, KY.
I need to replace the lateral lines and leech bed.
My questions are as follows:
How deep should I dig the trench for the lateral lines and fingers?
How much gravel should I use?
Should I use a screen around the flexible perforated pipe?
How long a run do I need with a 4 bedroom house. I intend to follow what is already in place and mal-functioning, with some overkill.
I want to do this myself to save money.
Any suggestions will be greatly appreciated.
