Backflow prevention devices are an essential part of protecting your home’s drinking water from contamination. If you’re a homeowner in Marin County, you may be required to install a backflow prevention device on your water service—whether it’s for your domestic water supply, fire sprinkler system, or irrigation. But when is it necessary, and what are the requirements for Marin Water customers? At Local Plumbing, we specialize in backflow prevention installations, testing, and repairs. Here’s what you need to know about keeping your water safe and in compliance with local regulations. What Is a Backflow Prevention Device? A backflow prevention device is a specialized valve designed to stop water from flowing backward into the public water supply. Backflow can occur when there’s a sudden drop in water pressure—like during a firefighting event or a major pipe break—causing contaminated water from private plumbing systems to siphon back into the municipal supply. Common contaminants include: Fertilizers and pesticides from irrigation systems Household cleaning chemicals Bacteria and debris from stagnant or non-potable water sources To prevent this, Marin Water requires certain properties to have backflow prevention assemblies installed and tested annually. When Do You Need a Backflow Prevention Device? Marin Water’s regulations specify that backflow prevention is required in situations where there is a potential risk of contamination. You may be required to install one if: 1. You Have a Fire Sprinkler System Fire sprinkler systems are often connected to the municipal water supply but contain standing water, which can stagnate over time. If backflow occurs, this water could re-enter the drinking supply. To prevent this, Marin Water requires all homes with fire sprinkler systems to have an approved backflow prevention assembly. 2. You Have an Irrigation System Irrigation systems can introduce contaminants like fertilizers, pesticides, and bacteria into your home’s plumbing. If your property has an irrigation system connected to Marin Water’s supply, a backflow prevention device is likely required. 3. Your Home Has an Alternate Water Source If you use a well, rainwater harvesting system, or any other alternative water supply, you are required to install a backflow prevention device to prevent cross-contamination between these sources and the public water system. 4. You Own a Multi-Unit Property or Commercial Building Certain commercial and multi-residential buildings are required to have backflow prevention in place to ensure the safety of all occupants and the broader community. How to Stay in Compliance with Marin Water’s Backflow Regulations Marin Water requires: Initial installation: If you are adding a fire sprinkler, irrigation system, or another potential backflow hazard, a backflow device must be installed by a licensed professional. Annual testing: Once installed, backflow devices must be tested annually by a certified backflow tester to ensure they are functioning properly. Repairs and replacements: If your backflow prevention device fails a test, repairs or replacement may be required to remain compliant. Why Backflow Prevention Matters for Your Home Besides meeting local regulations, installing a backflow prevention device helps: ✅ Protect your drinking water from potential contaminants ✅ Prevent costly plumbing issues caused by backflow contamination ✅ Ensure your home is in compliance with Marin Water’s requirements ✅ Avoid fines or water service interruptions due to non-compliance Need a Backflow Prevention Device Installed or Tested?
