PVC Leak under pressure

[kkutac001]

I have a question, not being very familiar with pvc. I made a 1/2" pvc "feed" line to my RO/DI. The line is under at least 40 psi. I used the purple primer and then glued all non-threaded parts. I just did my 'pressure test' and one elbow leaks.
My question: can I use the primer then slather a bunch of pvc glue on the leaking elbow joint? Does the glue actually meld/melt the two pieces together? If this 'slather' approach won't work, I'll have to cut out the joint and re-do it.
Just wondering if anyone has experienced this, or knows if I can fix it in-place, or if I need to cut it out and re-do it. Thanks! ...Karl

Cut it and re-do it, it'll leak sooner or later and keep an eye on all other glued connections.

As a pipefitter I can definitely recomend cutting and replacing it. Also you may want to try the blue "hot" glue that works in wet applications if you are in a hurry.

Thanks, guys. Guess that answers that! I'm not in a tremendous hurry, but thanks for the tip. Might be advice I'll need at a future troubled time, or that someone will benefit from if they read this thread. Many thanks! I'll "do it right". ..Karl

Quick follow-up: I cut out the offending elbow and replaced the fitting, with fresh glue, primer, etc... Waited 12 hours; did a pressure test a few mins ago: passed, so far. Thanks again for the good advice. ..Karl
