Standpipe
Each section contains twenty-four 1" holes per foot and is used in standard conditions with 4", 5", and sometimes 6" tile where the flow of a 6" inlet is not needed.
Riser
This is a 5" x 5/16" holed orange section used underground from the tee as a riser extension. It can be cut at different locations (as marked on section) to adjust the height of inlet.
Tee
This part is a 6" x 5" New Style Tee to be used to connect directly to 6" corrugated or dual wall tile and has a 5" inlet bell so that a 5" inlet can be snapped directly into the tee without the use of an adapter.
Restrictor
This is a 5" restrictor used to adjust the flow of water from the inlet to the main line.
SiltSock
Reducer Coupler
This is a reducer that connects 5" or 4" corrugated tile to a New Style Tee.

The capacity charts are based on the following assumptions:
- 50% of the holes in the inlet are plugged.
- There is no flow through the top of the inlet. The top of the inlet i either capped or the top of the inlet extends above the water elevation.
- The perforations in the inlet extend as high as teh water depth.
- The flow in the inlet is not restrited by any other component of the system. For example, flow is not restricted due to an orifice plate, and offset pipe that limits flow, or full pipe lfow in the mainline that could create a tailwater effect in the inlet.
