Aircraft nozzles must be equipped with a(n) ____________.

Explanation:
Aircraft nozzles must be equipped with an antisiphon or nondrip check valve. This device prevents backflow of the spray solution into the tank or into water sources when pressure changes or the system is shut off, protecting drinking water supplies and reducing the chance of contamination or unwanted drift. Other valve types don’t specifically provide this anti-backflow and nondrip protection, which is why the antisiphon or nondrip check valve is required.
