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

Question

PVC pipes are leaking at the Water Main line. Fixed it once myself and it still had a drip leak. Had a Plumber friend come out and fix my work. Still had a drip leak and small steady stream leak. Had him come fix it AGAIN yesterday and all seemed well, until my neighbor woke me up this morning and told me the water main box was flooded. I thought the guy who is a plumber would be able to get this resolved but things aren’t working out that way it seems. Are we not letting the glue set long enough? I mean this is the Water Main so it is very high pressure. I let the glue set for 3 1/2 hours last night before turning the water back on. When I turned it on I did it very slowly. My Plumber friend said he “likes” to let the glue set for 24 hours, but didn’t think it would be a problem after 2 or so. I am at a loss. Any advice would be appreciated. Thank you!!! Last night we even used the “grey” industrial strength glue/cement…

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

Mr. Durward Cummerata · Answer

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.

Mr. Durward Cummerata · Answer

Glue will set hard for use in 30mins or less. Sounds to me your using the wrong glue or your not using the right cleaner or not getting the pipe totally clean before you glue it. PVC is white. CPVC is a yellowish color. Makes a big difference in what glue you use.
