Answer 2

It appears your super has no clue in what he is doing if your talking PVC it should cure for atleast 16hrs before the water can be turned back on for the glue to cure.  It appears he should of hired a professional,  maybe you should and send him the bill or take it off the rent.  Really this is a total inconvience to you your paying rent to live in this place repairs should be done properly.
