    Default CPVC glue on PVC pipe

    Had a little mishap awhile ago. A couple of years ago, I re-plumed my whole house with PVC for cold and CPVC for hot water lines. A couple of weeks ago, I was going to shut off the water to a toilet when the PVC adapter to the shut off valve popped off. http://advice.thisoldhouse.com/images/smilies/mad.gif After getting the water shut off, I could see that the fitting had been primed, but could not see any evidence of glue, don't know how it held for over two years like that and never leaked.

    In my haste to get glued back in place, I accidently used CPVC glue instead of PVC glue. http://advice.thisoldhouse.com/images/smilies/eek.gif Can I expect this to hold or do I need to cut out and replace that section of the pipe and use PVC glue? Is there that much difference?

    Double check the small print on the can of glue. The "CPVC" glue I use also has PVC listed in the smaller print. You may be covered.

    Thanks, I used Oatay Medium Orange CPVC glue. I tried to read the fine print on the can and it said for use on CPVC, fittings and Schedule 40. Due to my age, its getting harder to read the fine print anymore.
