Didn't want to highjack a thread either with a discussion about the differences between SCH 80 nipples and male adapters for connecting valves. Here's a picture (hopefully sized appropriately) on a main line repair we did this week that clearly shows the angle configuration and TOE nipples we use. The valve originally ran with the main line but we decided to set it this way and reconnect using 2" 90s (pressure loss not a problem) because a 110v conduit to a parking lot light was placed in the same trench. This conduit was putting too much strain on the original valve location as it butted right against the valve body originally. This is a new school site (1 year old) that I didn't have inspection responsibilities for because it was total new site construction.
