That’s wild about the insurance—never even thought about them flagging “nonstandard” plumbing. I’ve been looking into rainwater setups for a while, but the backflow thing keeps coming up in code books. Did you end up using a double check valve or something fancier? I’ve heard some inspectors want a full RPZ, which seems like overkill for a toilet flush line. Wonder if the city’s just extra cautious with anything not off-the-shelf.
Yeah, the insurance angle threw me too—never thought they’d care about backflow devices, but here we are. For rainwater-toilet setups, I’ve usually seen double check valves pass inspection, but it really depends on the inspector’s mood (and sometimes what they had for breakfast). Some cities are just hardcore about RPZs, especially if there’s any chance of cross-connection. Honestly, for a toilet line it does feel like overkill... but once you mention “rainwater” or “greywater,” everyone gets jumpy. Ever tried explaining to an inspector that a flush tank isn’t exactly potable? That’s a fun conversation.

Man, I’ve been there—tried walking one through my setup and he just looked at me like I was nuts. Honestly, sometimes it feels like they’re more worried about paperwork than actual risk. I get the need for caution, but for a closed toilet line? Seems a bit much... but if insurance wants it, what can you do.
I get where you’re coming from, but honestly, I kind of appreciate the extra scrutiny. Maybe it’s overkill for a closed toilet line, but I’d rather have someone double-checking than risk a mix-up down the road. I’ve read stories about backflow issues causing real headaches, even if it’s rare. The paperwork is a pain, sure, but I’d rather be safe than sorry—especially with something as basic as water safety.
I totally get the caution, especially with backflow—nobody wants that mess. When I set up my rainwater system, the inspector was super thorough, which slowed things down but gave me peace of mind. Did you have to install a specific type of backflow preventer, or did the city specify what to use?
