I have an dolder house with iron pipes. The tub connects to the sink with 1 1/2 iron pipe then connects to the toilet. The toilet elbow was leaking which connected to an outside drain pipe 4". I'm going to do the toilet and drain in pvc, how do I connect the pvs to the old iron tub drain so it won't leak and so I don't have to replace all the old inron in the house? Is there a way to do it to code? How do you connect 2 pieces of iron pipe together that broke in the middle so it is code and won't leak? Thank u
