Florida Building Code Advanced04: Plumbing/Fuel Gas (1 hour)The 2004 Florida Building Code has undergone significant changes and it isthe obligation of all Florida licensed contractors to becomeknowledgeable of the changes that affect their ability to construct safeand secure projects. This course is not intended to supply core codetraining but is intended to update the contractor in recent changes. Thiscourse meets the updating needs of those contractors performing workunder the Plumbing and Fuel Gas segments of the FBC.When you have completed this course you will be familiar with the primarychanges of the plumbing and fuel gas sections from the 2001 code toprevious codes including:General regulations Water supply and distribution Sanitary and storm drainage Venting regulations Fuel gas combustion and ventilation Swimming pool requirements Residential plumbing specifications At the conclusion of the presented material you will answer a quiz. Uponsuccessful completion of the quiz you will download your completioncertificate. ATI will report your successful completion to the CILB. Theprogram contains three parts. Each part is timed. You must spend atleast 50 minutes total in the program.22

CHAPTER 3GENERAL REGULATIONS Significant changes 2000 International Plumbing Code significant changes: Added Table of products requiring third-party certification or testing Added requirements for condensate disposal – identical to FloridaBuilding Code, Mechanical 2003 International Plumbing Code significant changes: Added code conflict language Added alteration to trusses Added plenum piping requirement per Florida Building Code,Mechanical Added requirements for piping in flood hazard areas Added requirements for test gauges Changes as a result of previous DEC statement Sleeving is not required for installation of CPVC into concrete orsimilar material. Freeze protection is required where design temperature is less than32º F.6
CHAPTER 3GENERAL REGULATIONSSECTION 303 MATERIALS 303.4 Third-party testing andcertification.All plumbing products and materials have tocomply with the referenced standards. Alternative materials, design and methods ofconstruction and equipment may be allowed(Section 104.11 of Florida Building Code,Building) 7
CHAPTER 3GENERAL REGULATIONS Table 303.4 lists products and materialsrequiring third-parting testing and third-partycertification. 303.4 Third-party testing andcertification. All plumbing products andmaterials shall comply with the referencedstandards, specifications and performancecriteria of this code and shall be identified inaccordance with Section 303.1. Whenrequired by Table 303.4, plumbing productsand materials shall either be tested by anapproved third-party testing agency orcertified by an approved third-partycertification agency.8
Florida Building Code, Building104.11 Alternative materials, design and methods ofconstruction and equipment.The provisions of this code are not intended to prevent theinstallation of any material or to prohibit any design or method ofconstruction not specifically prescribed by this code, providedthat any such alternative has been approved. An alternativematerial, design or method of construction shall be approvedwhere the building official finds that the proposed design issatisfactory and complies with the intent of the provisions of thiscode, and that the material, method or work offered is, for thepurpose intended, at least the equivalent of that prescribed inthis code in quality, strength, effectiveness, fire resistance,durability and safety. When alternate life safety systems aredesigned, the SFPE Engineering Guide to Performance-Based FireProtection Analysis and Design of Buildings or other methodsapproved by the building official may be used. The buildingofficial shall require that sufficient evidence or proof be submittedto substantiate any claim made regarding the alternative.9

CHAPTER 3GENERAL REGULATIONSSECTION 305 PROTECTION OF PIPES ANDPLUMBING SYSTEM COMPONENTS 305.1 Corrosion. Added Exception: Sleeving is not required forinstallation of CPVC into concrete or similarmaterial.11
CHAPTER 3GENERAL REGULATIONSSECTION 305 - PROTECTION OF PIPES ANDPLUMBING SYSTEM COMPONENTS 305.1 Corrosion. Pipes passing through concrete orcinder walls and floors or other corrosive materialshall be protected against external corrosion by aprotective sheathing or wrapping or other means thatwill withstand any reaction from the lime and acid ofconcrete, cinder or other corrosive material. Sheathing or wrapping shall allow for expansion andcontraction of piping to prevent any rubbing action.Minimum wall thickness of material shall be 0.025 inch(0.64 mm). Exception: Sleeving is not required for installation ofCPVC into concrete or similar material.12
CHAPTER 3GENERAL REGULATIONSSECTION 305 PROTECTION OF PIPES AND PLUMBINGSYSTEM COMPONENTS 305.6 Freezing. Where the design temperature is lessthan 32º F (0º C), a water, soil or waste pipe shall notbe installed outside of a building, in attics or crawlspaces, or be concealed in outside walls in any locationsubjected to freezing temperatures unless adequateprovision is made to protect it from freezing byinsulation or heat or both. Water service pipe shall beinstalled not less than 12 inches (305 mm) deep or lessthan 6 inches (152 mm) below the frost line.13
CHAPTER 3GENERAL REGULATIONSSECTION 307 STRUCTURAL SAFETY [B] 307.4 Alteration to trusses. Truss members andcomponents shall not be cut, drilled, notched, spliced orotherwise altered in any way without writtenconcurrence and approval of a registered designprofessional. Alterations resulting in the addition ofloads to any member (e.g. HVAC equipment, waterheater) shall not be permitted without verification thatthe truss is capable of supporting such additionalloading. Since trusses are engineered products any alteration,drilling, notching, change, addition to weight, etc., mayprevent the truss from performing as designed.14
CHAPTER 3GENERAL REGULATIONSSECTION 307STRUCTURAL SAFETY 307.6. Piping materials exposed withinplenums. All piping materials exposed withinplenums shall comply with the provisions of theFlorida Building Code, Mechanical. Typically theplenum space includes the plumbing system aswell as the other building systems (fire,electrical and mechanical). Those materialsexposed within the plenum must be noncombustible or have a flame spreads index of25 or less along with a smoke-developed indexof 50 or less when tested (in accordance withASTM E 84).15
CHAPTER 3GENERAL REGULATIONSSECTION 312 TESTS AND INSPECTIONS 312.1.1 Test gauges. Gauges used for testing shall beas follows: 1. Tests requiring a pressure of 10 pounds per squareinch (psi) (69 kPa) or less shall utilize a testing gaugehaving increments of 0.10 psi (.69 kPa) or less. 2. Test requiring a pressure of greater than 10 psi (69kPa) but less than or equal to 100 psi (689.5 kPa) shallutilize a testing gauge having increments of 1 psi (6.9kPa) or less. 3. Tests requiring a pressure of greater than 100 psi(689.5 kPa) shall utilize a testing gauge havingincrements of 2 psi (13.79 kPa) or less. It's important to select and use the pressure gauge thatfits the range and design of what you are attempting tomeasure.16
CHAPTER 3GENERAL REGULATIONSSECTION 314 CONDENSATE DISPOSAL Added requirements for condensatedisposal—identical to Florida Building Code,Mechanical Section 307 (CondensateDisposal) Condensate piping is notplumbing. However it is covered in thissection because of the possibility ofplumbers installing such piping.17
CHAPTER 3GENERAL REGULATIONSSECTION 316 IRRIGATION Added to this section: 316.1 General. Irrigation/sprinkler systems andrisers for spray heads shall not be installed within1 foot (305 mm) of the building sidewall.This section was originally part of Section 1503.4.4Florida Building Code 2001.The purpose of this section is to limit possible soildisturbances near the foundations of buildings.Liquid soil termiticide applied to these areas duringconstruction can be easily disturbed by subsequentlandscape operations and water input rendering afailed termiticide barrier. Inclusion of droughttolerant plants into landscape plans can aid inachieving this goal.18
