Transparency in Water Regulations and Updates

Annual Backflow Testing

Backflow prevention devices are essential to stop contaminants from entering the public water supply. Regular annual testing ensures these devices function correctly, maintaining water safety for all users.

Protecting Community Water

Testing backflow devices prevents harmful substances from reversing into the water system, safeguarding the health of the entire Marvin Estates community and surrounding areas.

Compliance and Safety

Priest Lake Water LLC follows state and federal regulations requiring annual backflow testing to uphold water quality standards and prevent contamination risks.

Homeowner Responsibility

Homeowners with backflow prevention devices must schedule annual tests to confirm proper operation, helping protect both their property and the shared water supply. Within ground watering devices, such as sprinklers, yard hydrant with multiple hoses attached, hoses filling travel trailers and RVs, kid pools etc., need to have a anti siphon vacuum breaker.
