applicable plumbing code requirements.
PLBG 103 Drainage, Bathroom, Kitchen and Laundry –
Plumbing Rough
This course provides students with the technical knowledge
and practical skills required to perform above-ground drain,
waste, and vent (DWV) rough-in installations for residential
and commercial buildings. Students develop competencies in
the layout, sizing, and installation of drainage stacks,
branch drains, vent systems, fixture drain connections,
traps, cleanouts, and roof drainage components serving
bathrooms, kitchens, and laundry areas. Emphasis is placed
on drainage system design, venting methods, drainage fixture
unit (DFU) calculations, blueprint and isometric interpretation,
and the coordination of rough-in installations prior to
fixture setting. Students also develop the skills necessary
to evaluate system performance, verify proper drainage flow
and vent protection, and prepare complete DWV rough-in
systems for successful code inspection and subsequent
fixture installation.
PLBG 104 Fixture Setting, Toilets, Sinks, Water Heaters and Trims
This course provides students with hands-on training in
plumbing fixture installation, water heater installation,
trim-out procedures, and final plumbing system completion.
Students will learn installation techniques for toilets,
lavatories, sinks, faucets, shower trims, water heaters,
and related plumbing accessories. Emphasis is placed on
plumbing code compliance, leak prevention, customer service,
troubleshooting, and professional installation practices.
PLBG 105 Plumbing Estimation, Professionalism and
Customer Relationships
This course prepares students for professional plumbing field
operations by emphasizing estimating procedures, customer
service, professionalism, communication skills, plumbing
business practices, work orders, and field documentation.
Students will develop practical business and interpersonal
skills necessary for successful employment in residential
and commercial plumbing environments.
PLBG 106 Troubleshooting and Repair
This course develops the advanced diagnostic, troubleshooting,
and repair skills required to service existing residential
and commercial plumbing systems. Students learn to
systematically evaluate plumbing system performance,
identify the root causes of water distribution, drainage,
venting, fixture, water heater, pump, and plumbing equipment
failures, and implement appropriate repair and preventive
maintenance procedures. Emphasis is placed on diagnostic
techniques, hydraulic and basic electrical principles,
service documentation, customer communication, and professional
decision-making while restoring plumbing systems to safe,
efficient, and code-compliant operation through hands-on
service and repair activities.
PLBG 107 Water Treatment and Filtration, Septic Tanks
and Grease Traps
This course introduces students to water treatment systems,
filtration technologies, septic tank systems, grease traps,
and wastewater management procedures used in residential
and commercial plumbing applications. Students will learn
installation methods, maintenance procedures, troubleshooting
techniques, and applicable plumbing and environmental
regulations.
PLBG 108 Advanced Backflow Prevention and
Cross-Connection Control
This course introduces students to advanced concepts related
to backflow prevention, cross-connection control, and potable
water protection. Students will learn installation,
maintenance, inspection, and troubleshooting procedures for
backflow prevention assemblies used in residential and
commercial plumbing systems. Emphasis is placed on public
health protection, plumbing code compliance, contamination
prevention, and practical applications.
PLBG 109 Fuel Gas Systems
This course provides students with the knowledge and practical
skills required to install, inspect, test, and evaluate
residential and commercial fuel gas systems in accordance
with applicable plumbing and fuel gas codes. Students learn
the properties of natural gas and liquefied petroleum (LP)
gas, fuel gas piping materials, pipe sizing methods,
corrosion protection, combustion principles, gas appliances,
regulators, meters, venting systems, combustion air
requirements, and pressure testing procedures. The course
also covers fuel gas system design, isometric drawings,
material take-offs, leak detection, bonding and grounding
requirements, system inspection, commissioning, and code
compliance. Emphasis is placed on safety, proper installation
techniques, regulatory compliance, and the application of
industry standards to ensure the safe and efficient
operation of fuel gas systems.
PLBG 110 Comprehensive Laboratory Hours
This course provides students with comprehensive review
activities and integrated practical applications covering
the entire Maintenance Plumbing Technician Program. Through
assignments delivered on the institution's Interactive
Distance Learning (IDL) platform, virtual simulations,
troubleshooting exercises, case studies, quizzes, blueprint
interpretation, code review activities, and scenario-based
laboratory projects, students reinforce the theoretical
knowledge and practical skills acquired throughout the
program. Emphasis is placed on plumbing system integration,
code compliance, troubleshooting procedures, customer service
scenarios, safety practices, and preparation for employment
in residential and commercial plumbing environments. The
course is designed to strengthen students' competency,
confidence, and readiness for field operations through
asynchronous online learning activities. This course is
completed entirely through the institution's Interactive
Distance Learning platform and does not require on-campus
laboratory attendance. Note: Although scheduled on-campus
laboratory attendance is not required during this course,
the instructor remains available to provide academic support
and answer students' questions as needed.
