I have 2 main lines in my crawl space for sewer drains to spetic system.
One 4" line runs 3 feet east to west and crosses over the South to North line, turns and runs North to South for 25-30 feet. It has all the 2 inch drains and 3 toilet drains( 4 in) connected to it.
Then turns 90 deg and runs 10 feet, turns another 90 degrees and then runs 30 feet South to North to the septic tank with no connections on this 30 foot line.
There are no clean outs on the lines. Last time we had a blockage the plumber ran a snake the whole length from the shower to push and clear the block.
Can I just reconnect all the drains to the South to North run ? Any Issues?
