[Plumbing] Drain cover

I am wondering how to replace a drain cover in a cement floor in a garage? The current one in the pic below is all rusted out and crumbling.

chisel it out, just be careful not to cut up the threads in the pipe if possible.

I am sorry, what do you mean how? Just remove it (somehow) and replace it with a plastic one. The new plastic once are easy to install.

It doesn't look that bad, just dirty (note that ALL cast iron floor drains will have a coating of rust). It looks like maybe they got concrete on it when they poured. I have several of these in my house. I just loop a coat hanger or other stiff wire through the holes and pull them up and out. You probably don't need to replace - just clean. If this is a garage, you probably do not want plastic. It will break if it gets driven on.
The cast iron drain covers can literally last longer than you.

NM, My eyes tricked me with an optical illusion. I see that it's cracked. The cast iron replacement is about $10. Measure the diameter to make sure you get one that fits right.

Once you remove and clean the cover you can coat it with navel jelly which contains phosphoric acid or soak it in phosphoric acid, which is a reducing agent that turns iron oxide into iron. Clean the drain and then coat it with navel jelly. Wash the phosphoric acid off with hot water. Wear heavy rubber gloves and eye protection. Phosphoric acid burns skin and corneas. The iron will come out with a nice blackened coating.

I use a large flat blade screwdriver and a hammer to remove the existing rusted lid, then scrape around the base of the drain to clear out any remaining crud.. Dont let any metal fall into the drain, and I recommend to flush the drain with a 5gal bucket of water, as fast as you can pour it. This clears and tests the flow of the drain.

Naval jelly isnt a bad idea on any rusted stuff, but a new lid comes painted. Your lid is toast. Do not buy a plastic lid, they are 2x as thick as iron, and will stick up above the floor, as well as not support any weight. Nunya's link above is a good place to grab the correct diameter lid..

good luck

if it aint broke, tweak it!!
currently on FiOS (kick aZZ!)

What nunya stated, do not get plastic for the garage.

Remove the old one and get a new metal one.

Keep the old one and bring it with you to either a plumbing shop or a hardware store.

Easy as that.
