What is the purpose of running the system with an open faucet during installation?

Running the system with an open faucet during installation serves primarily to clear air from the system. When installing water treatment systems, such as water softeners or reverse osmosis units, air can become trapped within the plumbing. This air can lead to undesirable operational issues, such as inconsistent water flow or system malfunctions. By running the system with an open faucet, water flows continuously, displacing any trapped air and helping to ensure that the system operates efficiently and effectively from the outset.

This step is a crucial part of installation as it promotes optimal functioning of the water treatment system and reduces the chances of air-related problems later on. Ensuring that air is vented out before closing the system is an essential practice for maintaining the longevity and performance of the system.
