I contracted Guardian Enclosures to design and build an enclosure to protect our backflow system at my Church. We had very specific needs due regarding placement and installation and Wayne and his team built exactly what we needed at a price that was more than fair. Even after several years, the enclosure looks great.
I highly recommend Guardian Enclosures.

FAQ

Cost?
A Cost? The cost of a backflow prevention device for residential protection can be anywhere from $100-$200.00 dollars plus the cost of having a licensed plumber install it. Backflow devices for other applications may be substantially more expensive.
What are the Potential Hazards of not having a Backflow Prevention Device?
A What are the Potential Hazards of not having a Backflow Prevention Device? Contamination or pollution of a water system is usually brought about by a cross-connection to any systems containing auxiliary water supplies which may be polluted or contaminated; irrigation systems which may be polluted or contaminated with fertilizers, pesticides or other objectionable materials. Thus, using a hose-attached sprayer for application of pesticides, solvents, cleaning products, etc; flushing a car’s cooling system with a garden hose; or filling a swimming pool can all create situations where cross-connection can occur. Without proper protection, devices as useful as your garden hose have the potential to poison your home’s water supply. In fact, over half of the nation’s cross-connections involve unprotected garden hoses!
Why do I need to test my backflow assemblies?
A Why do I need to test my backflow assemblies? The state regulations and/or the Uniform Plumbing Code require testing all assemblies annually. But regulations aside, keeping all of your assemblies in good condition not only reduces your legal liability exposure, it also lowers your actual maintenance costs as well. It’s smart to catch problems while they’re minor, rather than wait until an emergency arises, such as when a device starts to dump hundreds of gallons of water per minute out it’s relief valve into an office or room. Annually testing your devices is the only way to guarantee that all internal components of your device are working.
What are my on-site backflow assemblies for?
A What are my on-site backflow assemblies for? On-site assemblies are devices installed in your facilities at the point of cross connection to prevent on-site backflow occurrences. It is these devices that actually provide protection to your staff and/or customers, rather than the assemblies at the meter, which protect the city main lines. The plumbing code requires that on site assemblies be tested annually also.
What is the impact of the Backflow Codes?
A What is the impact of the Backflow Codes? Water purveyors have started cross-connection control programs, and must mandate the installation and annual testing of backflow devices at the user’s meter for system protection, wherever an actual or a potential backflow hazard exists on site.
