Connecting a Sink to Fire Water Line
Connecting a Sink to Fire Water Line
(OP)
I'm working on a small 500 SF pump station on an airport, and the owner wants a service sink the building. The civil engineers want to tap into the fire hydrant loop just outside the building for the sink and label everything non-potable.
I've never seen this done before, but I can't find anything in the code the strictly prohibits it. It just sounds like a bad idea. Any input would be appreciated. Thanks.

Typically, in non residential applications, a reduced pressure zone (RPZ) will be required to protect the municipal source from anything. Typically, a second backflow preventer (usually another RPZ) would be downstream to use the water as non potable. In this case, since there are no other water uses, only one RPZ would likely be required.
Service sinks (and hose bibs) are a historic (and notorious) culprit for back siphonage and or backflow contaminating municipal services.
In the IPC areas, 602.2 indicates that potable water shall be supplied to all plumbing fixtures.

as LCREP said if the line is a dedicated fire loop you might be in for a surprise if you plumb this sink.
