We’re debating the need to replace our 100 year old toilet stack with PVC. We need some professional opinions: what are the downsides to working with either material?
Thanks! -
There are both easy to work with if you know how. cast iron is heavy, need cutter to cut it are sawzall, clamps and torck wrench. Pvc is light, need saw cleaner, glue and gloves and eye protection. Best to have Plumber do it.

Thanks for the reply-
Are there downsides to having it replaced with PVC? Will it be as durable or last as long? Which do you think is the better alternative?
Also, we have a section of the stack in the basement that was spliced with about a 12 inch section of PVC. (we don’t know when or why). Structurally, is this a problem? It’s at the bottom of the stack and it’s sitting in there kinda crooked. Should we replace that section with cast iron if we don’t convert it all to PVC? Does it matter? -
The downside to PVC is that it is noisier, you can hear water draining thru it. With the repair that was made it sounds like the pipe may have not been properly supported and will continue to settle from the weight of the cast iron.
