Question

If you intend to draw water from surface waters of a stream, ditch, pond, lake, river, or from a public water supply to fill your pesticide application equipment, what device is required by Ohio law to prevent backflow?

a. A stainless steel valve before tank and at inlet
b. An in-line strainer to prevent dirt, algae, and other contaminants from entering the spray tanks
c. An anti-siphon device
d. A roller pump, plus the steel valves with a strainer

Answer 1

An anti-siphon device is required by Ohio law to prevent backflow when drawing water to fill pesticide application equipment from surface waters or public supplies.

Step-by-step explanation:

When drawing water from surface waters such as a stream, ditch, pond, lake, river, or from a public water supply to fill pesticide application equipment in Ohio, it is required by law to use an anti-siphon device.

This device is designed to prevent backflow, which could potentially contaminate the water source with pesticides. The anti-siphon device ensures that if there is any change in pressure, contaminated water from the pesticide application equipment does not siphon back into the water supply.
