What must be ensured for piping during the pouring of concrete?

When pouring concrete, it is essential to ensure that the piping is under pressure. This is to confirm that there are no leaks in the system, which could result in problems after the concrete has set. Pressurizing the pipes allows for the detection of any potential issues before they become sealed within the concrete. If any leaks are present and the pipes are not pressurized, they may go unnoticed, leading to significant complications, like water damage or structural issues, once the concrete hardens.

Additionally, maintaining pressure on the pipes during this process helps prevent them from becoming crushed or deformed by the weight of the wet concrete, which can occur if the pipes remain unpressurized. Therefore, ensuring that the piping is under pressure during the concrete pouring is a critical step in safeguarding the integrity of the plumbing system.
