Even if you have to cut PVC to change it out and use a coupler with new piece of PVC to connect back should take no more then 10 mins to do and you can turn the system back on after another 10-20mins of drying time.
I try to stay away from any sealants or glue to fix problems like this as it is more of a patch then a true fix to the problem and could likely return in the future. Better to fix the issue the right way the first time around.
