A 2 1/2- to 8-inch pipe with up to 160 psi requires a 90-minute wait time in 60- to 100-degree temperatures and 24 hours for pipes with a psi of 160 to 315. That time increases to four hours when you're working in temperatures of 40 to 60 degrees and up to three days for pipes with up to 160 psi.

How long after gluing CPVC can you turn water on?

The CPVC glue instructions say 15 minutes to handle and 12-24 hours to cure if you're above 60 degrees F.

How long does CPVC take to cure?

Allow 15 minutes for good handling strength and 2 hours cure time at temperatures above 60°F before pressure testing up to 180 psi. Longer cure times may be required at temperatures below 60°F or with pipe above 3".
