Galvanic Reation...Exit Points
Galvanic Reation...Exit Points
(OP)
Someone please explain how I would determine if and how
bad a galvanic reaction may occur in a water distribution
system...
Also, what are some modeling techniques to show a
reaction in a water line if all the toilets were
flushed at the same time? Just a little humor, but
I really need to know this...thanks.

RE: Galvanic Reation...Exit Points
I don't know of specific modeling techniques for your flushing problems, although you may be able to simply estimate the peak flow by timing the flush cycle, calculating your gpm based on the gallonage of your toilet divided by the seconds to cycle, multiplying your number of toilets, and model based on this flow. You are right that you could have a real problem, especially if you are using flush valves. Even a 1.6 gallon low-flush valve pulls that amout of water in 2-3 seconds, giving you a brief spike flow of about 30 gpm. If you had 4 flush valves get punched simultaneously that's 120 gpm. That could be a bit more than your piping can handle. I saw this exact situation once and its was causing water hammer that was traveling several miles through a 4" water main, and that was with only two toilets flushing simultaneously.
