If the city's building code doesn't specifically require a backflow preventer, what should you do?

Choosing to install a backflow preventer, even if the city's building code does not specifically mandate it, is the most prudent course of action due to several reasons related to public health and safety. A backflow preventer is a crucial device that helps prevent contaminated water from flowing back into the clean water supply, thus protecting against potential health hazards.

Installing a backflow preventer demonstrates a commitment to responsible environmental practices and ensures compliance with best practices in plumbing and landscape irrigation. This proactive measure can avert potential contamination issues, which can arise from various factors such as changes in water pressure or cross-connections.

Furthermore, even though the local code may not require a backflow preventer, it is essential to consider any state regulations, health department guidelines, or industry standards that might recommend or require such a device to safeguard the quality of the water supply in the area.

While informing the owner of the regulations is important and necessary, taking immediate action by installing the device shows an advanced understanding of the importance of water safety, potentially preventing future problems. Ignoring the requirement or waiting for a request can lead to severe consequences, including health risks, liability issues, and violations of broader safety standards that could exist beyond the city code.
