Well the pipe just showed up and there was a mistake. The 8" came straight and not belled. I could use couplers but the pipe only pushes in about 4" on them compared to 6" on the belled stuff. Back it goes. I also ordered a trash guard, 10ft of 4" pipe and broke down and bought the 10" cleanout. It's almost $300.00 just for the cleanout!!! Thats crazy
