The local 'big box' has 6' white IPS PVC DWV with cellular core. I've
done a little research and it is unclear if I can use the white PVC for
an outside replacement of the 6" Clay pipe. The codes on the DWV pipe
indicate it is F-891-00, schedule 40, NSF, and JM 30/35. The building
department for the city has told me I can use schedule 40. But is the
white OK for US outside applications? I know green is usually used.
Any advise is appreciated.

Correction that's 6" white IPS PVC. What I am doing is replacing clay
pipes that have developed a leak. The whole thing is complicated by
the number of exits from the house on this run and a chipmunk that has
created a cavity under part of the pipe. . There are 3 cast iron
exits within 12 feet. It is a septic conversion. Would also like to
ask about fitting all the connections together. I bought rubber donuts
that will convert the 2" and 3" cast iron to 4" plastic. And I have a
4" to 4" rubber ring for the 4" cast iron. It seems like the only way
to make this work is to make one connection at a time starting from the
clay to PVC connection. Plan is to:
Dry fit and mark the pipe to the first connection to make sure it will
fit.
Disconnect and install the donut on the first connection so that it is
back far enough to not interfere with the putting the last PVC piece
in place.
Then connect the PV to clay (rubber boot) and glue my way to the first
connection off a PVC T connector.
Finally pounding the donut into the PVC. Then repeat to the next
connection.
Having difficulty imagining how to make sure it all fits correctly.
Using cross marks at the connectors will help on the PVC. But the clay
to pvc connection will be harder to mark and get correct. Any
corrections to the above or other ideas would be helplful.
