Plumbing Codes

The start of plumbing codes, local enforcement officials determined they would be better off using a “model code” rather than writing their own for every jurisdiction in the country.

Model codes are just that: a comprehensive model. A model code, like a product standard, is not self-existing but must be adopted by a governmental jurisdiction to become “law”. Model codes are usually written, published and maintained by membership organizations comprised of code enforcement officials.

Organizations were formed to write model codes, which were largely “regionalized”:

Plumbing codes are the basis for acceptance of materials for specific plumbing installations and for the methods of installation.

While many jurisdictions adopt model codes as they are published, these jurisdictions also have the power to amend codes when they are adopted. The following organizations and their model plumbing codes accept the use of plastic for piping applications:

NATIONAL PLUMBING CODE
Building Officials and Code Administrators International (BOCA)

UNIFORM PLUMBING CODE
International Association of Plumbing and Mechanical Officials (IAPMO)

INTERNATIONAL PLUMBING CODE (ICC)
International Codes Council

STANDARD PLUMBING CODE
Southern Building Code Congress international (SBCCI)

ONE AND TWO FAMILY DWELLING CODE
Council of American Building Officials

NATIONAL STANDARD PLUMBING CODE
Plumbing, Heating, Cooling Contractors – National Association

ANSI A40, SAFETY REQUIREMENTS FOR PLUMBING
Accredited Standards Committee A40
American National Standards Institute

NFPA 501, STANDARD FOR MANUFACTURED HOUSING
National Fire Protection Association

ICC/ANSI 2.0-1998
(Formerly CABO Manufactured Housing Construction Safety Standard)
International Codes Council

As a professional plumber one must know not only the plumbing codes but the local accepted plumbing codes to pass inspection. The required Continue Education has helped keep licensed plumbers updated but a professional has to continue all year keeping up with the trade.

SAFE-T-SWITCH A/C OVERFLOW SHUT-OFF SWITCHES WITH STATE-OF-THE-ART MICROELECTRONICS

HOUSTON, TX – The RectorSeal Corporation, a Houston-based manufacturer of specialty products and tools for the HVAC industry, has expanded its line of patented  Safe-T-Switch® condensate overflow control switches with two new models, SS103E and 500EP. These electronic switches are reliable, easy to install and are code compliant.

As with all Safe-T-Switches®, the new models are designed for use in new or retrofit applications to protect home and commercial building owners from costly damage due to condensate overflow. The new electronic condensate overflow switch contains a low power consuming, state-of-the-art microelectronics. The A/C units will stop when the probes detect water. They offer A/C specialists an easy way to insure customer satisfaction and reduce potential liability.

The new SS103E switch can be installed horizontally or vertically, inline or on the primary pans auxiliary drain outlet and the secondary overflow pan. The dual sensor control provides added protection with the simplicity of installing a single device. The logic circuit continuously samples the probes for water. Onboard LED’s indicate the condition of the unit at a glance indicating an overflow condition currently or in the past 4 days. The SS103E is listed to UL 508.

The SS500EP is a plenum rated switch for installation on primary or secondary drain pans. The small, easy to use bracket fits perfectly in commercial roof top units. The simple 2-wire design is a state-of-the-art microelectronics that uses less energy. As with the SS103E, the onboard LED indicator removes the guess work on the condition of the unit.
