What is the primary purpose of opening faucets during installation?

Opening faucets during installation serves the primary purpose of draining and depressurizing the system. This step is crucial to remove any air trapped in the water lines and prevent pressure build-up, which can lead to potential issues such as pipe bursts or water hammer. By allowing water to flow out of the faucets, technicians can ensure that the system is completely drained and properly set up before the installation of new equipment. This practice also helps to clear out any debris that may have accumulated in the pipes, providing a cleaner working environment for the installation.

Checking for leaks, facilitating a faster installation, and ensuring proper water flow are valid considerations during installation, but they are secondary to the crucial step of draining and depressurizing the system. The focus on preventing pressure-related problems takes precedence in ensuring the safety and effectiveness of the installation process.
