If a valve is installed in the reverse orientation, what is the effect on water delivery?

• A. Water flows to adjacent zone
• B. Water remains in pipe
• C. No water to the zone
• D. Pressure increases

Answer: (C)

Valves are designed to allow flow in a specific direction. The inlet and outlet are aligned with internal parts (like the diaphragm or seat) so water can pass from supply to the zone when the valve is energized. If the valve is installed in reverse, that exact flow path is misaligned, and the valve cannot open properly to let water through. The result is that no water reaches the irrigation zone, even though the system may be pressurized. To fix it, reinstall the valve with the correct orientation, making sure the supply side feeds the inlet and the outlet goes toward the zone (look for the flow arrow on the body).
