Don't think it will work but 1 way to find out. Get a can of primer and glue. Most probably the purple stuff you see is the primer and the glue is clear. Prime it up and seal it up with glue and see if it works. Otherwise see if possibly it wasn't glued properly and you can split it apart and redo the seal. If neither of the above work you will have to cut it out and redo with new pvc pipes.
