Does every service connection need some type of backflow preventer?
The answer is, not necessarily. DHH requires protection of the water system from high health hazard locations as a minimum. If your program is established only on state minimum standards, then it is probable that not every service connection will require backflow prevention. High health hazard locations include businesses such as, but not limited to, hospitals, nursing homes, mortuaries, car washes, beauty shops, etc. Non-high health locations typically include businesses such as, but not limited to, CPA firms, attorneys, engineering/architecture offices (without laboratories), etc. Residential properties usually are not required to have backflow preventers at the meter; however, it the Louisiana Building code requires hose bib vacuum breakers at all hose bib connections.
