What must piping embedded in concrete undergo before the concrete is poured?

Piping that is to be embedded in concrete must undergo pressure testing before the concrete is poured. This testing is crucial as it ensures that the piping system is free from leaks and can withstand the anticipated pressure that will be exerted on it once it is encased in concrete.

Conducting a pressure test involves filling the piping with water or air and allowing it to hold the pressure for a specified duration. Any drops in pressure would indicate potential leaks or weaknesses in the piping that must be addressed prior to being encased, as once the concrete is poured, accessing the piping for repairs becomes significantly more challenging and costly. This testing is an important quality control measure to ensure the integrity and reliability of the piping system in its final location.

Utilizing other types of tests, such as heat testing, leak testing, or insulation testing, would not specifically confirm the integrity and safety of the piping under pressure in the context of being embedded in concrete prior to the concrete pour.
