Help With Sewer Storage Tube

[ole dude]

I used 4" DWV. The 90 degree elbow fit in the tube O K. Had the ends that were added to the pipe so I could put a screw cap on each end. However, I did have to trim a little off the end of the sewer hose that connects to the rigs drain line. Added a second pipe and was able to put a new Rihno hose with fittings in it, again had to do a little trimming. Found that pipe in 10 foot lengths. Take your elbow with you and make sure it will fit. Hope this helps. DWV-drain-waste-vent.
