    Can I replace the 4" cast iron floor drain cover myself?
    I have a 4" cast iron floor drain cover that is corroding due to the salty water from when my water softener recycles.

    How can I replace this drain cover? Do I have to replace with another cast iron drain cover? I'm afraid I'm going to have the same issue in a couple of years if I do. Can I use a plastic ABS 4" drain cover? If so, how do I make the transition?

    I have 3 drains "routed" to that floor drain. Please see picture.

    You should be able to chisel out that cover. I'd break most of it out from the center. Then put a strong chisel along the edge and try to drive sideways into the opening to collapse the remaining ring. PVC or CPVC should be as good as ABS

    Agree with Ballengerb. In addition, I would suggest that you take the old cover with you to Home Depot and buy exactly the same size but in plastic. Cast iron is unprotected metal and will corrode rapidly if exposed to salt.

    Thank you for your quick reply.

    Do I need to do anything special with the new plastic drain cover? Or do I just pop it in? The label on the cover says, "may be solvent welded or inserted inside of 4" schedule 40 DWV ABS pip. Pipe can be cut flush with the finished floor."

    So, if the salt water is corroding the drain cover... I'm sure the pipe itself is probably going to be affected the same way. How do I tell if the pipe is cast iron? Will I need to have a professional replace the pipe?
