    But the system might still be under a guarantee. No question, there will be some marginal systems that will lose their effective lawn coverage when the RPZ goes in.

    I wholeheartedly agree with you on the pressure issue. However, an original system would be warranteed with the original backflow device. If that device has to be changed in the future then the original warranteed configuration is null and void. Probably a moot point anyway since most changes in ordinances like this would also contain a grandfathering clause.

    Heck, we still have hundres (maybe thousands) of systems in the area that still have AVBs trying to act as PVBs. Not sure when the change was enacted in our building codes here (probably 30 years ago), but nobody makes them change them out either. Hardly any policing of that in Colorado.

    No grandfathering around here, that I'm aware of. Given how the local and state governments hold the hammer on an issue regarding the safety of the public water supply, they're under zero obligation to cut anyone any slack.

    Its been a VERY long time ago (well, actually only about eleven years), but I had a PI in Dallas, TX approve replacing a swing check on a very old system. It all depends on attitudes, legislation, and the pocketbooks that are provided to enforcement. All the pretty code you can write doesn't amount to squat if you won't put teeth in them with fundable enforcement.
