Good morning:
Have a 50' run to city riser, according to my calculations I need to hook up to the riser appx. 12.5" down the riser from ground level to give the run 1/4" per Ft. . What fittings do I need to hook up to a 4"riser? I assume it's a sweep surely not a 90 degrees.
Thanks in advance
Mike

When we run a sewer out to the street raiser we use a 45 degree/ eighth bend fitting to angle down and connect to the city. Good luck, Tom

Thanks Speedball, We are just about to turn on the town, OFF THE SEPTIC at last. It's been raining all month in Coastal N.C. and you know what that means on a 50 yo system
Thanks again
Mike

Did you know that the rain run off from your SC mountains replenishes a under ground river that feeds the Florida Aquifer? Next month I might just be drinking your rain water.
Good luck on your sewer hookup, Tom
