Did I read this Pontoon Beach Public Water District letter correctly..? If I have any kind of back-flow preventer such as an in-line on my exterior spigot, fixed air gap, or any other type, I have to allow (and pay for?) some plumber to come in once a year and inspect it? When did this begin? WTF? Whats next? An electrician coming in yearly to inspect my ground fault switches? Tell me we aren't going down this road!
