I did search the forum (good search is "book" in titles only), but didn't find what I'm looking for. I'd love a good book a step back from "how-to" - about the fundamentals of plumbing. The terminology, the physics of water flows and vacuums created, the mechanics of washers, gaskets, pipes, slip vs compression vs threads... A whole chapter on washers would be nice - plastic, brass, rubber, reducing, flat, tapered, flanged, thin, thick - a book explaining *why* things work and what general problem fittings/etc. are trying to address, rather than a case-by-case how-to. I understand this is the kind of thing you only TRULY learn via experience, but the same can be said for philosophy and I really benefit from reading Kierkegaard
I've been trying to fashion my own low-algae, low maintenance, low cost chicken watering system and have iterated because of leaks / low flow / algae (too much light goes right through 5 gallon bucket HDPE). I'd love to have a better feel for materials and fittings and when and why they're applied, such that I'd be able to design, say, my own bulkhead by choosing from among a few appropriate materials and components. Thank you for this forum, it's a wonderful place! I'd like to get to the point where I could offer help as well as ask for it ... So, any recommendations for deep books on fundamentals?
