This obviously for a drain line. Drains are never under pressure, so I think your OK. Just a tip that maybe you haven't picked up on. When connecting ABS or PVC just apply the solvent to one joint at a time. A good swab around the inside of the fitting and a good swipe around the outside of the pipe end. Then insert the pipe into the fitting with a twisting motion as well as pushing. Then hold the joint together for a few seconds so the pipe won't push away from the bottom of the fitting. All that said, I'd bet there are lots of joints that are working just fine that did not get all of the above done to them.
