Backflow Prevention
Backflow Prevention
(OP)
Are there any codes or standards that require that backflow preventors are installed to ensure that water used for human consumption is separated from water that can potentionally be contaminated by chemical processes in industial applications. Thanks for any help.

Based on what you have said - I would think you should do so - regardless of codes!!!

So just do it!!!
RE: Backflow Prevention
I agree with what you have said. The only reason I am asking for codes is it makes it easier to convince the tight pocket clients when I have them to back me up. Thanks for your respones.

In a process plant, the owner typically wants to isolate his potable water from that used by his process. A secondary backflow preventer is usually installed.
