Check with your city, town or municipality or whatever it is called in your
area, they will have specifications that you need to work with. Here on the
internet, we don't even know the country you are in, so how can we help?

I'm going to have to replace my ancient (61 year old) 4" Orangeburg with
PVC. I'll be burying the new line unbedded decomposed granite, about three
feet deep. Should I use 3034 or Schedule 40 PVC?

TIA
