OK, you engineer types. I forgot to mention that I had also installed a copper threaded double male union between the aluminum hot water heater outlet & the braided stainless steel hose. Now I have 3 different metals in play. Will I still have a galvanic corrosion problem or would I be better off with an aluminum to cpvc to stainless combo or should I just place the old plastic plug in service again or, is this 'much ado about nothing?'
