Ok, if I did it right, I have attached a couple of pictures. The first shows the flared ends of two of the pipes, the one on the left being the one I cut the flared part off of. The 2nd picture shows an 90 degree elbow attached to the cut end of the first pipe,while the 2nd pipe has another pipe inserted into the flared end. If I attach the elbow (or any other fitting) to the end where I cut the flared part off, it is way too loose. If I attach the same fitting to the other end, which was not flared to begin with, it fits perfectly.
I would have thought the pipe was of uniform diameter along its entire length, until it got to the flared part, which of course is bigger so you can fit another pipe into it. It appears however, that the pipe may taper down to a slightly smaller diameter just before the point at which it flares out, or maybe I got a weird pipe? I was just curious if it was supposed to be that way. It would seem to limit the usefulness of the pipe if you wanted to attach fittings to both ends. One thing I guess I could do is cut off a short length of pipe from the non-flared end, and insert it into the flared end. At the cost of an extra joint, I should be able to get two pipe ends of the same diameter.
I was going to solvent-weld these drain pipes in the hopes of keeping roots out. If the fit is loose, will the PVC glue be able to form a bond? Being a drain pipe, it won't be under pressure, I just need to keep it from leaking and keep root fibers out.
Thanks,
