I just replaced rusted-out 300 gallon steel septic tank with a code compliant norwesco 1000 gallon tank. Because of size of tank and slope of property the inlet on tank is about 12” lower than on previous unit. Would it meet code to increase drop of inlet pipe to 45 degrees for last 3-4 feet of run? I could maintain 1/4” per foot for the first 20’ but would use 22-1/2 degree fittings to increase drop to get waste pipe into tank. Otherwise, I would have to excavate new trench from house to tank.
Thanks!
