i would not use it... especially if the system would see glycol. The zinc in it can react w/ the other metals and give you issues. kpc

    galvanized black pipe

    I have some left over galvanized pipe. Can I use this on a hot water heating system? Or will I creat corrosion problems. I know its not allowed on steam for inspection purposes but what about hot water? Thankyou in advance.
