I bought and installed a system back in 2000 from Heatway and as far as I know there has been no maintenance done. I would like to know how to check to see if there is or was ever any additive added for corrosion (CP-3) that is alluded to in the manual. I can not find any information on this product??
What other maintenance should be done?
In the FAQ sections that question is there, but no answer is provided.??
