How long must pipe and fittings be cured before installation of sprinkler heads to prevent damage?

Curing the pipe and fittings before installing sprinkler heads is essential to ensure the integrity and durability of the connections. When solvent cement is used on PVC or CPVC pipes and fittings, it requires adequate time to cure and develop the necessary strength.

Curing for 30 minutes is generally recommended because it allows the solvent to evaporate sufficiently, forming a strong bond between the materials. This period helps prevent any potential leaks or failures that can occur if the joints are disturbed too soon. Taking the time to properly cure the joints leads to a reliable and efficient fire protection system that functions effectively when needed.

In contrast, shorter durations such as 5, 10, or 20 minutes do not provide sufficient time for the solvent to fully cure, increasing the risk of joint failure during installation or later use. By allowing the recommended time for curing, you ensure the durability and safety of the sprinkler system.
