I have a drum trap below the bathtub that's leaking. I have complete access to it in the basement. It looks like the bottom of the trap, where you would crank on it with a wrench, is corroded and that's where the water is leaking from. Does any place sell replacement parts for these or am I stuck having to replace the entire thing with PVC? I checked Home Depot and Lowe's and neither of those places sell what I need. Any suggestions?

Thanks so much!
