Galvanized Steel Pipe in contact with Cast Iron Pipe
Posted by Bob D. on June 19, 19100 at 14:25:32:
Is there a potential corrosion problem with galvanized steel pipe that is connected to cast iron pipe without any dielectric union or sacrificial anode? Also, what do you think is the best type of material to use for drain pipes. I would like to use a plastic such as polypropylene or CPVC because corrosion shouldn't be much of a problem. Thanks for your advice.
