A few days late but wanted to review the alert; proposed TIA's and comments in addition to the Literature Review and Research Plan from CCI (some consulting firm) :D and the FPRF before posting. It is worthwhile information to review and get familiar with while being prepared for a TIA (Tentative Interim Amendment) to come out in August or September after the NFPA Standards Council’s review of the requested UL research and testing:

FM,

Thanks for sharing this information with us.

I could list a volume of examples of backflow preventers failing; and antifreeze poisioning; but, it would just fall on deaf ears; or I suppose I should say seen by blind eyes.

When the best backflow prevention devices are installed properly; and, yes even when they are tested and serviced in accordance with the manufacturer's instructions and/or State laws; they fail with amazing regularity!

Antifreeze is an extremely dangerous poison; that kills people, animals, fish, and plants. And, we allow it to be put into a system, that is connected to our public water supply.

But.... you can't have a dry system that complies with NFPA 13-D, either.. .right?

AS I RECALL.. there's no maintenance required on a 13-D, since it comes off the domestic system .. and as I recall.. all the proponents of the code change lined up and said "YES.. vote for it"

Just askin'
