Yesterday, I started an effort to clear a blockage from my 60 year old cast iron drainage pipes. Before it was over, the rusty, old pipes were cracked and leaking. So today I am replacing the old iron P-traps with PVC. First order of business is cutting the old pipe. All I have is a sazall and some diamond blades (at Home Depot). I don't have access to a snap cutter. I've never tried this before and not sure what I'm in for. Well, wish me luck.
