4. Corrosive Water -- Means potable water with pH levels below 7.0 or water whose physical and chemical properties cause it to dissolve pipe, fixtures, and accessories thereby shortening their ordinary life or causing the water to violate drinking water standards.
5. Plate or Board Support – A plate or wood backing that is nailed or screwed to the stud or studs to provide a rigid support for the pipe or tubing.
6. Potable Water – Potable water is water that is satisfactory for drinking, culinary and domestic purposes, and meets the requirements of the State Department of Health.

9. State Administrative Authority -- Means the State Health Officer or his/her designee that administers and enforces the provisions of the State Plumbing Code as adopted or amended.
10. Water Service Pipe – The water service pipe is the pipe from the water main or other source of water supply to the building served.
11. Water System – The water supply system of a building or premises consists of the water service pipe, the water distributing pipes and the necessary connecting pipes, fittings, control valves and all appurtenances in or adjacent to building or premises.

1. CPVC water pipe shall not be installed within 6" of any gas appliance vents or within 12" of any recessed light fixtures.
2. This regulation does not allow (CPVC) to be installed for temperature & pressure relief line discharge on water heaters.
3. CPVC is approved for above concrete installation only. However, CPVC may be installed under the slab or concrete of a residential building plumbing system when the State Administrative Authority has determined that corrosive water will have an adverse effect on metallic piping. It shall be the responsibility of the person(s) requesting to use CPVC to provide proof that the public or private water source supplying the plumbing system is corrosive before the State Administrative Authority can approve CPVC pipe for underslab installation.
4. This regulation applies to residential living units having four (4) units or less whether under a single roof or separate buildings and share common property boundaries. CPVC water pipe is expressly prohibited in commercial buildings.

1. Piping systems components shall be constructed entirely of new and unused parts and materials.
2. Piping systems components and materials shall have been evaluated and found to be suitable for their intended usage by a testing agency recognized by the authority having jurisdiction.
3. When requested, the manufacturer shall furnish evidence acceptable to the authority having jurisdiction concerning the composition of the materials used in all components of the piping system.
4. The construction of parts not specifically covered by this regulation shall be in accordance with reasonable concepts of safety, substantially and durability.
5. Cutting and joining of tubing shall be done in compliance with the manufacturer’s recommendation.

The manufacturer shall provide complete detailed instructions, including appropriate illustrations, necessary for proper installation and use of the piping system. Included in the instructions shall be statements to the effect that:

1. Piping systems components shall be constructed entirely of new and unused parts and materials.
2. The installation must be in accordance with the manufacturer’s recommendations and the applicable state/local plumbing codes and regulations.
3. Precautions must be taken by the installer to ensure any exposed tubing is not damaged or abused during building construction or reconstruction by using approved protectors.
4. Only the components provided or specified by the manufacturer as part of the piping system are to be used in the installation.
5. Installation clearance holes for routing the tubing through studs, joists, plates, etc., shall have a diameter ½ inch greater than the outside diameter of the tubing.
6. Each branch run of tubing intended to serve plumbing fixtures and equipment shall be securely fastened in place and included as part of the pressure test.
7. Horizontal runs shall be supported with a minimum distance of 36".
8. Vertical runs shall be supported with a minimum distance of 5’.
9. Provisions shall be made to allow adequate clearance between tubing and the structure (bores holes or sleeves) to allow freedom of movement due to thermal expansion and contraction.

This regulation applies to piping system for use with potable water system with pressure/ temperature ratings of not less than 160 psi at 73.4 º F, 100 psi at 180º F.

1. Each component of a piping system (tubing and fitting and manifold shall bear a permanent marking of the following):

1. Manufacturer’s name, trade-mark
2. Symbol of the organization making the test for compliance with the regulation

B. Tubing shall bear a permanent marking of the following:

1. All (CPVC) tubing shall be marked with its appropriate classification as described in the definitions Section III.
2. ASTM & SDR number.
3. Temperature & pressure rating.
4. The words potable or initials NSF-PW.
5. The markings specified in Section VIII paragraphs A and B shall appear on the tubing at not more than 5’intervals.

If any provision of these regulations, or the application thereof to any person is held invalid, such invalidity shall not affect other provisions or application of these regulations which can give effect without the invalid provisions or applications, and to this end the provisions hereto are declared to be severable.
