My first question is does flux go bad? I bought some flux about 8 years ago to do a repair job and was about to use it again. It doesn't look separated or anything. Just curious if the chemical composition degrades over time.
Also, in doing some recent research, I've found that 'water soluble' flux is required for all potable water systems. Can anyone tell me if the flux I have is water soluble? It doesn't say as such on the container so I'm guessing it probably isn't.
Rectorseal C-flux, Product Code 74026, Lead Free, Acid Free
It was a plumber working at a big box retailer that initially sold me the flux for my repair project and, as it was lead free, I had assumed it was the correct stuff to use. If not water soluble, can someone recommend a good water soluble flux to use?
Thanks for any help.
