| AWWA used to NOT recommend BPA upstream of fire hydrants. Haven’t checked in a few years now. And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them an heart of flesh Eze 11:19 Backflow preventers are actually not always required. NFPA standards do not require them – but where the water purveyor does, NFPA provides installation requirements. When a back flow is required, the type and location are the purview of the water district.
If arranged to allow full forward flow, a hydrant or even the annual fire pump test or standpipe flow testing could qualify as the means to perform a forward flow test

FYI,
A question from an AHJ. In many cases, we receive a dedicated underground fire line to serve fire hydrants and the building fire sprinkler system. (Domestic if provided through a separate line)
When this occurs, the local water authorities always require a backflow (in an underground vault) to separate the public water supply from the private water system.
With this approach, we do not require a backflow on the riser and use the yard hydrant system for the forward flow testing of the backflow.
Does anyone see an issue with this approach? If so, please advise we can revise our procedure.
