What is crucial to remember before pressure testing joints?

The emphasis on waiting before pressure testing joints is vital because it allows for the proper curing and stabilization of any adhesives, sealants, or other materials used in the assembly of the joints. Rushing into a pressure test before the materials have adequately set can lead to inaccurate test results or potential failures, as the joints may not yet have achieved their intended strength or integrity.

While waiting for 24 hours or sealing joints with adhesive may seem relevant, the most universally applicable principle is simply to allow for an appropriate waiting period without specifying a fixed time or additional steps. Ensuring joints are in direct sunlight is less relevant since the effectiveness of pressure testing largely depends on the curing process of the materials and environmental conditions, not necessarily direct sunlight exposure.
