@SlicerDicer @sun i've actually seen building codes updated over the past couple decades saying that over a certain % of renovation requires fire suppression, but then of course you get people cutting corners to not do it

its an expense but is it really a wild expense in the long run to have a dry cpvc system, i dont think so, but this is the world we live in, and they can easily be installed on existing domestic systems with the proper backflow preventers, but i guess if the infrastructure takes a shit on delivering the water you're still fukt, or if the system is overwhelmed by a massive fire

maybe these events will get people to look at alternative building that works with the land and avoids some destruction, maybe they'll get more into permaculture, but probably not
