How long to let PVC Pipe glue set before turning on water main?

It’s actually a solvent and should be okay to use within an hour. As the other poster said, I’m suspecting someone is not prepping the PVC (clean it) or using the right glue.

Also be sure you are holding the lines together for awhile when you insert the fitting because they will sometimes try to push away from each other, while the glue is wet.

I’ve used different glues with different drying times. Some glues might require the fittings to be dry. Be sure to use a solvent cleaner made for cleaning the connections prior to gluing and use on the male and female ends. Look for deep scratches or a hairline crack. Be sure the line is fully inserted into the fittings and again hold them for a minute or so so they don’t push away from each other. Drying time should be printed on the can. Any pvc glues I have used held pressure in less than the 3 1/2 hours you allowed.

How To Glue Pvc Pipe

Sorry for responding to an old thread but nobody has posted the correct answer. PVC glue joint integrity varies based on a number of factors. #1 is the pressure. To what max pressure will the joint be exposed. #2 is the pipe diameter. The larger the diameter, the longer the cure time needed to achieve fixture or working strength. A third is temperature. The glue will set up faster at the ideal temperature. Hotter or colder will create a weaker joint. This is not to say that you can t bend any of the rules…they are just guidelines established by many experimental results that prove the ideal conditions for welding the two pipes together.
