My understanding is flyash is the service and they wanted to use 12" .406 wall but we received standard wall material instead. My question with little wall thickness diffrence what are the pros and cons of using standard wall piping instead of schedule 40 (.406). I do not even have a line...
Fly Ash service line any reason why you can't use standard wall verses schedule true 40. There's only thousands wall thickness difference.
Thanks in Advance !
