If the inlet port is blocked in a sprinkler valve, water cannot flow into which component?

Explanation:
The key idea is how a diaphragm sprinkler valve uses pressure in the upper chamber to control opening and closing. When water is able to reach the valve, the pressure in the upper chamber pushes the diaphragm toward the valve seat to close the passage. If the inlet port is blocked, the upper chamber cannot become pressurized, so there’s no force driving the diaphragm to seal. Without that closing pressure, the valve stays in the open position. So water cannot flow into the upper chamber, and the valve would remain open.
