If you go to the big box store for 4-inch S&D pipe, be sure to look at the
markings. If it is ASTM-D2729 or SDR-35, it is not a so-called "IPS"
compatible pipe. Make sure you get compatible fittings! You'll want large
radius sweeps for 90-degree bends.
All IPS pipe sizes have the same actual outside diameter for a given trade
size. Schedule 40 and schedule 80 are IPS sizes. So fittings might be
easier to find. You can find IPS pipe in thinner wall than Schedule 40.
Pipes maked SDR-xx (except for the SDR-35) are IPS sizes. The larger the
number, the thinner the wall. Check with a local plumbing or irrigation
supply for SDR-41 or SDR-61 (the later having almost the same wall
thickness as 2729 pipe).
All electrical conduit is IPS sized, so you can use conduit sweeps with
white IPS pipe, and this might actually be the easiest, though not
necessarily cheapest, way to acquire large radius sweeps.

Your local big box stores should be your best source. I use 4" PVC
sewer/drain pipe which is less expensive. It has a thinner wall and flared
ends so no fittings are needed.
