Sarge Posted October 26, 2019 Share Posted October 26, 2019 Hey plumbers. I just ran some CPVC lines and used the orange cement made for CPVC. Just read the label and it says leave water off 12-24 hours! I kind of need to get the water back on LOL. Does it really need to cure that long?

GrumpyOne Posted October 26, 2019 Share Posted October 26, 2019 It shouldn't. The reason they want you to leave it off is to cure and so you won't taste it. It really only takes about 2 hours to completely cure. Per Oatey Hold pipe and fitting together for 30 seconds to prevent pipe push-out - longer at low temperatures. Wipe off excess. 10. Allow 15 minutes for good handling strength and 2 hours cure time at temperatures above 60°F before pressure testing up to 180 psi. Link to comment Share on other sites More sharing options...

I checked the website and found what you posted but the label on the can says 12-24 hours. That’s what threw me. I have always just glued PVC and turned the water back on but this orange CPVC glue seems different. For the night I turned the water on and no leaks. But I had to come home so I turned the water back off since nobody is home there tonight. Link to comment Share on other sites More sharing options...
GrumpyOne Posted October 27, 2019 Share Posted October 27, 2019 It'll be fine. Most water systems only have about 60psi, and full cure time is for 180psi. Link to comment Share on other sites More sharing options...
toothandnail Posted October 27, 2019 Share Posted October 27, 2019 Clean , glue, turn on water, maybe wait 5 minutes at most. i will shut off water every night for the first 2 days if it's new construction or remodel and no one around at night.
