When are backflow prevention devices required in fumigation?

Backflow prevention devices are essential in fumigation practices to maintain the integrity of water sources and prevent contamination. When fumigation is connected to a well, installing backflow prevention devices is critical. This is especially vital as the fumigation process can involve potentially hazardous chemicals that, if backflow occurs, might enter the well and pollute the water supply.

This requirement is part of regulatory measures aimed at protecting public health and the environment. While backflow prevention may also be relevant in other scenarios, the direct link to well-connected fumigation setups underscores the necessity in those situations. Fumigation connected to a well poses a higher risk of chemical intrusion into potable water, highlighting why backflow prevention devices are mandated specifically in such cases.
