It looks like you have ABS elbows (black parts at top of photo) with PVC piping. Is this so? I do not think you can glue those 2 together successfully, as the glues for each are different. Can anyone else validate my claim, if this is the case?

You are right. ABS and PVC should generally not be used together however this is a non pressurized line and we used a cement that bonds to both plastics. It is safe in this case. We consulted a plumber friend of ours because our local plumbing supply store was sold out of the PVC fittings we needed and we didn't want to wait the extra 7-10 days to bring in the elbows.
