The Elite Software DPIPE DOS based program quickly calculates optimal pipe and vent sizes for sanitary building drain systems with up to 400 pipe sections. Existing drainage systems can also be analyzed because DPIPE allows the designer to fix the size of any and all pipe sections. Besides sizing reports, DPIPE can also print a complete bill of materials showing both labor and material costs. Branch, sewer, and stack pipes along with branch and stack vents are automatically sized in accordance with the BOCA code.

DPIPE also has provision for sizing pipes using codes different from BOCA. In fact, you can define and maintain as many sizing code files as necessary. DPIPE is very easy to use as it contains built-in data concerning fixtures, pipe materials, and pipe fittings. DPIPE does allow the user to maintain various material files, and each material file can contain up to 96 different fixtures, 72 pipe fittings, and 16 material types.

PROGRAM INPUT
The DPIPE program uses full screen editing features that provide a simple "fill in the blank" input procedure. All input data is checked at the time of entry so that no improper data can be entered. If you have a question about what the program is requesting, you can press the "?" key which allows the program to offer additional explanations about the input data being requested. Upon completion of the input process, all data is saved to disk and can be reviewed and edited whenever desired. Two types of data are requested: general project data and pipe segment data.

The general project data includes the project name and location, building drain and main sewer elevations, the maximum and minimum allowable pipe sizes, and the default pipe material. The pipe data requires that each pipe section be defined as having beginning and ending node numbers along with a type specifier such as branch, stack, sewer, branch vent, or stack vent. In addition, the length, material type (cast iron, copper, steel, PVC, etc.), fitting quantities and types, and connected fixtures must be specified for each pipe section. For designers who do not want to specify detailed fixture information, there is an option for entering a direct drainage fixture unit (DFU) value for each pipe section. Options are provided to quickly view, edit, add, or delete pipe sections. Input sheets are provided for the easy organization of your data.

PROGRAM OUTPUT
The DPIPE Program provides the following four basic output reports: general project data, pipe size data, vent size data, and a bill of materials with complete cost data. In addition to these reports the built-in pipe data, fitting data, and drainage fixture data can be printed. The user can specify exactly what reports are to be printed. All reports can be printed to the screen, printer, or to a disk file. Options are provided for specifying the starting page number, and the desired left hand margin.

CALCULATION METHOD
The DPIPE Program follows the methodology described in the American Society of Plumbing Engineers (ASPE) Data book and the Basic/National Plumbing Code/1988 published by the Building Officials & Code Administrators (BOCA) Corporation. As new codes emerge, DPIPE allows you to easily change the sizing tables. All results computed by the program can be easily verified by hand to be in accordance with ASPE and BOCA code requirements.
