Anti-drain valves are found on which hose condition?

Anti-drain valves are used to keep water in a hose once the system is shut down. They function when the hose is wet and under pressure, so that after you close the nozzle or release pump pressure, water doesn’t drain out of the hose. This keeps the hose primed and ready for quick re-pressurization. If the hose is dry, there’s nothing to drain, and the valve isn’t doing anything; dry-hose conditions don’t require this feature. So the best fit is wet hose under pressure, where preventing water loss is most needed.
