"No DI/DW will not stop corrosion, but it will help to minimize it. High resistivity electrolyte will slow the e-chem process."
this is true, and a stupid recommendation for WCing systems; such water in the presence of mixed metals is ionic in minutes
-> why make ineffective recommendations ?
(distilled water is worthwhile, but to minimize the contaminants in the system)
"Galvanic or disimiler (sp) metal corrosion (al rad and CU block) may be a problem within some peoples WC systems. In most cases there won't be a metallic path so their will be no need for concern."
so you are commenting on something that is not an issue ?
-> show me a SINGLE instance of such please
"A piece of thin zinc ribbon submerged in part of the WC loop (say the res or T line) then connected to the object that is to be protected (the Al rad) would likely provide enough Cathodic Protection to reduce the corrosion rate to a crawl."
wrong, and this is a DUMB error
you persist in your efforts to demonstrate what ?
zinc won't do shit with alu and cu
-> what is this "would likely" wording ?
if you do not know, shut the lower jaw and stop posting speculation dressed up as fact
and the corrosion product of your sacrificial anode ?
is that not contamination ?
do you think your pump will like it ?
-> then don't put it in the system to begin with
your resistance to comprehension exceeds my interest, I am abandoning the field
