Backflow prevention is a critical part of protecting your water supply from contamination. Businesses and commercial properties in Ocala and Marion County are required to have backflow prevention devices tested regularly to comply with local water authority regulations. Miller and Sons Plumbing provides certified backflow testing, installation, and repair services for commercial properties throughout the area.
Backflow occurs when contaminated water flows backward into the clean water supply, usually due to a drop in water pressure or a cross connection in your plumbing system. Without proper backflow prevention, harmful chemicals, bacteria, and other contaminants can enter your drinking water.
Our licensed technicians are certified to test, install, and repair backflow prevention assemblies. We help businesses stay compliant, protect their water supply, and avoid costly fines or shutdowns.
