Noise from PEX/PVC drain pipes
We are at the stage of starting the framing for the new construction home in Pittsburgh. It is also a Passive House duplex. Our architect specified cast iron for domestic water drainage pipes (from shower and toilet, etc.), mostly on the account that these result in most quiet interior. For delivery of the water within the house, PEX is planned. Then we heard that iron pipes are more susceptible to clogging. Is some compromise, where pipes close to dining/living room are cast iron, and PEX elsewhere an OK option?
At GBA, I did read on environmental life cycle comparison already between PEX and iron, lean towards PEX on this account, but would like to minimize these kind of noises. What would be recommended and what else should we consider..?
