I thought a Watts 9D was designed for an outdoor spikot and if vented to the atmostphere. In doors, if that 9D decided to vent, lots of things would get wet. What am I not understanding? Best Wishes

Backpressure regulator

the Watts 9d says 'vent' on it because it was in the ceiling w/ no floor drain possible i was able to just leave it...inspector ok'd it.....it will leak on the ceiling tiles when it goes bad.

being that it is a coffee maker they will most likely require the relief drain since it is a vacuum break which the ones without the relief do not have - - - - - - - PLUMBERS "Protecting The Health Of The Nation"

It sounds to me like you understand it well. While the inspector may not care, it sounds like a poor install. If it opens up, things get wet.

When you say "vent" do you mean the "relief" port between the 2 checks ? If that is what you are talking about I would highly suggest piping the discharge to a drain or outside. If that backflow where to discharge and get trash in it and get stuck in an open position, very much water damage could be done. They make the backflow preventers without the discharge but you would have to check local authority if is approved for that application. ... ......... X ..... Good Luck .....

Our inspector would require that the "vent/discharge" be piped through the ceiling at least so it would NOT damage the ceiling tile.

All the makers have their own ,that I installed feed lines for, as well as regulators.You could contact the service dept of the maker to verify.I would spend the time to check with the inspector on this one. Edited 1 times.
