[TowerTalk] Sourcing PVC

[Art Greenberg]

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.
