My daughters tub has a lego toy stuck past the clean out pipe. We can't get the pipes apart at any of the joints. The house was built around 1947 and has the original galvanized pipes. My questions is, without replumbing the whole thing, how do you attach PVC pipe to galvanized pipe without it leaking? I thought we might be able to cut the pipe, get the lego out and attach a length of PVC pipe in it's place. Any thoughts? Or do we call a plumber? She has a limited income. Thanks!
