No problem. And Au Contrair, I absolutely can explain "it. And with pleasure, I assure you. The trend in this thread is interesting in that we have user "JoshH" politely speaking nothing but the truth, when forum member "Engloid" became aggressive and insecure at the revelation that his plumbing method of the Beananimal system was proven to be inferior. Youll notice that "JoshH" was nothing but polite and a true gentleman during the entire discussion and was understandably perplexed as to how said aformentioned forum member "Engloid" couldnt wrap his head around the fact that what he ended up with is nothing even close to a Beananimal standpipe system. But as requested; Sure! Ill delve further into why plumbing all of your standpipes into a single header, or in effect, a common manifold, renders the flood failsafe capabilities of a Bean obsolete. Quite simply, you have created a single point of failure by plumbing all of your standpipes into one header. Those in risk management would designate your system as a 100% fail risk. You may, possibly, enjoy the flow capabilities of the open channel and full siphon from this system, but as JoshH mentioned, you absolutely are not covered by the systems flood failsafe capabilities. Its very simple physics. Your argument of "I wont hold my breath waiting on 1.5" pipe to clog up. Its been running about five years so far," is far from a credible one. (All it takes is a stray plastic bag to empty your entire tank onto the floor of your house. 1.5'" is not a cozy, worry free pipe diameter)
As reefers we prepare for Murphy's Law. The worst case scenario. Just because no ill effects have been suffered thus far is not indicative of the integrity of a system or even close to a relevant rebuttal. Your argument, lacking any sort of substance to bolster your take, has simply been, and I quote" It works." Copy that. Congratulations. Of course it "works". Its a few holes in a tank with the aid of gravity. I could drill a few holes in my tank with a 3/16" drill bit and plumb it with some Capri Sun straws draining into my sump and it would "work." That doesnt mean its a good idea. This topic transcends the lines of any personal disagreement in this particular thread and thats why i chose to engage. This is a discussion forum. Sometimes there will be differences of opinion. If you want to run a system with a single point of failure risk, thats your prerogative, but others should be advised as to the proper way to plumb an overflow so as to potentially avoid a devastating flood.Carry on.
