A seacock may be installed instead of a siphon break to prevent discharge and back siphoning. True or False?

A seacock can indeed be used instead of a siphon break to prevent discharge and back siphoning in certain plumbing systems. A seacock is a valve that, when closed, prevents the passage of water into or out of the vessel through the hull. By closing the seacock when not in use, it effectively eliminates the risk of back siphoning, since there would be no open water path to draw from.

It's important to note that while seacocks can serve this function, they must be installed and maintained correctly to ensure they work properly and provide a reliable means of preventing back siphoning. Safety protocols and best practices should always be followed to ensure that the seacock is accessible and operable when needed.

In contrast, siphon breaks serve a different function, often allowing water to flow while creating a break in the water column to stop back siphoning. Using a seacock as an alternative requires a full understanding of the system's design and intended use to avoid potential issues.
