Ok, I have a question.
This crossed my mind when gathering some fittings to finish assembling my rig. Why does it seem like everybody is avoiding brass and copper like the plague? I understand that some people would be worried about copper toxicity, but would it really reach anywhere near the amounts that would show any signs of illness? I mean, copper is used as a common fungicide for many vegetable plants. Granted overdoing the application would do harm to the plant, but still the concentration of copper in the fungicide would be at least hundreds of times more concentrated than any sort of copper leaching out of fittings (I would imagine).
I mean, prior to coming out of your faucet, the water goes through numerous feet of solid copper pipe water line, past numerous brass valves, and finally exiting out of a normally brass crafted garden hose nozzle.
I'm just curious what the reasoning is behind buying specialty stainless pressure relief valves/gauges/check valves. I mean if you were THAT concerned about that much copper leaching out of the yellow brass, you should be concerned about the lead leaching out too... lol... I can see avoiding making huge long runs using copper pipe as a nute transport between chambers in a large grow room, but couldn't see brass or copper making any difference in a small setup like most of us have.
Like I said, I also avoided brass where I could, but in a few places I had to useo, not trying to argue a point or change anybodys mind. I just want to know the reasonings behind your decisions
