Water supply safety and contamination are the responsibility of property owners. One way to achieve this is by installing a backflow prevention system. However, simply having a backflow protection cage or enclosure installed is not enough. It needs to be the right size for your property. Choosing the right size backflow enclosure can be overwhelming, but it doesn’t have to be. What is a backflow enclosure? A backflow enclosure or backflow protection cage is an enclosure that houses a backflow prevention system. This system prevents contaminated water from flowing back into the main water supply lines. A backflow prevention system usually consists of several components such as check valves and air gaps that work together to protect against contamination. Why do you need a backflow enclosure? In commercial and industrial properties, backflow prevention systems must be installed by law. Fines and legal actions can result from noncompliance with regulations. Even if you do not fall under these requirements, you should still install one since it protects your property from potential health hazards caused by contaminated water.

 Right Size Backflow Enclosure

Selecting the right size enclosure begins with determining what kind of backflow prevention system you need. There are two types: Reduced Pressure Zone (RPZ) and Double Check Valve Assembly (DCVA). RPZ systems are usually used in high-risk areas where contamination is high. DCVA systems operate in low-risk places with less contamination likelihood.

Measure the area where you plan to install the covering to ensure it’s large enough to accommodate the system and any necessary maintenance.

Whether your area has any regulations or specific requirements regarding backflow prevention measures. Municipalities may require a particular enclosure size or installation guidelines. Consider future growth when selecting an enclosure size. If you plan on expanding your property or adding new equipment that requires additional water usage, you may need a larger backflow prevention system in the future. Follow manufacturer recommendations for selecting the appropriately sized enclosure for your specific backflow prevention system model. They’ll guide you on what size enclosure is needed based on their product specifications. Climate and weather conditions in your area when selecting an enclosure.
