Lowe's website says that houses built since 1985 have backflow preventer built into the water meters. Googling seems to say that only houses with sprinker systems have them. Which is true?
Before I put an expansion tank on today my pressure would go from 50 (where the PRV was set) up to 90 (which is the feed pressure); so I presume my 2006 house doesn't have one; but I could be wrong.
