Air: Lock Plumbing

This uses gravity and pressure to naturally bleed air:

At its core, an air lock is governed by the principles of fluid dynamics. Plumbing systems are designed to be "closed" environments where water moves under pressure. However, when a pocket of air enters a pipe—often at a high point or a bend—it can create a physical barrier. Because air is compressible and less dense than water, the standard pressure from a header tank or a local water main may not be strong enough to push the air bubble through the system. This trapped air essentially acts as a plug, resisting the force of the water behind it and causing the system to fail. Common Causes air lock plumbing

Unlike water, air is highly . In a plumbing system, air naturally rises to high points or bends in the pipework. When a large enough air bubble forms, it can create a pocket of resistance that the system's pressure is unable to overcome, especially in low-pressure, gravity-fed systems.
