I assume that the combo would be in the horizontal section of pipe just before the first long sweep 90 that will take me vertical. Correct?
Is the native soil acceptable to lay the pipe on? If yes, do I need gravel to haunch up to the springline of the pipe or will broken and compacted soil...
Greetings,
Need a sanity check prior to digging the trench this coming weekend. I need to connect our 4" discharge line that is currently going to our septic tank to a newly installed grinder station that is part of the sewers recently installed.
The existing 4" line is approximately 24"...
