Learn to design real domestic water, DWV, venting, storm drainage, and specialty plumbing systems — fixture units, pipe sizing, hot water systems, backflow prevention, medical gas, and plumbing codes.
21 modules and 5 complete real-project design packages, with worked calculations, field documentation, and a certificate of completion.
Plumbing engineering scope, the project lifecycle, and the codes landscape.
Distribution layout, pressure zones, pipe materials, and water conservation.
WSFU and DFU concepts, Hunter’s Curve, and probability-based sizing.
Velocity limits, friction loss, and sizing for peak demand.
Water heater types, sizing, recirculation design, and Legionella control.
Booster, ejector, sump, and circulator pumps, and pump curve basics.
Cross-connection hazards, backflow preventer types, and testing requirements.
DWV layout, drain sizing, slope requirements, and trap function.
Why venting matters, vent types, sizing, and common code violations.
Roof drainage design, rainfall-based sizing, and overflow requirements.
Grease interceptor sizing, interceptor types, and maintenance.
Medical gas systems, NFPA 99, and specialized certification requirements.
The two dominant model codes, key differences, and jurisdictional adoption.
Drawing set organization, isometric risers, and coordination.
Rough-in vs. trim-out, pressure testing, and trade sequencing.
Pressure testing, backflow field testing, and commissioning documentation.
Real diagnostic scenarios covering common real plumbing problems.
Apartment building fixture takeoff, riser sizing, and DWV stack design.
Domestic plumbing plus a full NFPA 99 medical gas system design.
Multi-floor stacked restroom core with DWV and vent sizing.
Grease interceptor sizing and selection for a commercial kitchen.
Pressure zone breakdown, booster pump sizing, and PRV placement.
12 real project templates — a fixture unit takeoff worksheet, pipe and riser sizing calculation sheet, grease interceptor sizing worksheet, backflow preventer test and certification report, medical gas system verification log, water/DWV pressure test report, riser and pressure-zone diagram checklist, fixture schedule, submittal log, RFI template, punch list, and an as-built and commissioning documentation checklist. Available for download from Module 20 (Documentation & Resource Kit) once you've unlocked the program.
Coming later: sample isometric riser drawing files and video demonstrations. Not included in this release.
