§ 15.08.190. Additions, modifications and amendments to the Uniform Plumbing Code.

A.

The sections of the Uniform Plumbing Code designated below are modified to read as follows:

 604.1 Materials[:] Water pipe and fittings shall be of brass, copper, CPVC or PVC manufactured to recognized standards, subject to the following restrictions: (A) Only copper or CPVC may be used for hot and cold water distribution systems within a residence. Such installation of CPVC pipe must maintain not less than an 18-inch horizontal separation from any heating appliance. (B) PVC or CPVC underground services must include a Type K copper connection extending from shut-off valve, through basement wall or foundation and eighteen (18) inches beyond undisturbed soil, and eighteen (18) inches past undisturbed soil from a meter housing. SDR9 CTS, 200 PSI, ASTM D2737 Flexible polyethylene pipe and tubing (natural virgin core with blue Virgin Exterior) may be used at the meter instead of K Copper. PEX underground pipe may be used when sleeved going through the foundation or basement wall in the same manner as K Copper sleeved eighteen (18) inches beyond undisturbed soil. K Copper may still be used if a plumber so chooses.

 605.2 Valves and Fittings: Valves up to and including two inches (50.8mm) inside diameter shall be of brass or other approved material and all fittings used to carry water shall be copper, brass or other approved material except non-galvanized cast iron fittings with inside diameters over two inches (5.8 mm) may be used for water.

 701.1 (a) Drainage piping shall be cast iron, Schedule 40 ABS, Schedule 40 PVC, extra strength vitrified clay pipe, or other approved materials having a smooth and uniform bore, except that:

701.1.1 No galvanized wrought iron or galvanized steel pipe shall be used.

701.1.2 ABS and PVC DWV piping installations shall be limited to those structures where combustible construction is allowed.

701.1.3 No vitrified clay pipe or fitting shall be used above ground or where pressurized by a pump or ejector. Such pipe or fitting shall be installed at least twelve (12) inches (.3m) below ground surface.

 701.2 Drainage fittings shall be of cast iron, Schedule 40 ABS, PVC, or other approved materials having a smooth interior waterway of the same diameter as the piping served and all such fittings shall conform to the type of pipe used.

701.2.1 Fittings on screwed pipe shall be of the recessed drainage type.

Burred ends shall be reamed to the full bore of the pipe.

701.2.2 The threads of drainage fittings shall be tapped so as to allow one-fourth (¼) inch per foot (20.9mm/m) grade.

 707.1 Each cleanout fitting for cast iron pipe shall consist of a cast iron or brass body and an approved plug. Each cleanout for other types of pipe shall consist of a brass plug as specified in Tables 7-6, or a standard weight brass cap, or an approved ABS or PVC plastic plug. Plugs shall have raised square heads or approved counter-sunk rectangular slots.

 707.4 An approved type of two way cleanout shall be extended not less than three (3) feet nor more than five (5) feet outside of buildings or dwellings and extended to grade.

 710.6 Backwater valves, gate valves, motors, compressors, air tanks and other mechanical devices required by this section shall be located where they will be accessible for inspection and repair at all times.

 719.1 Additional building sewer cleanouts shall be installed at intervals not to exceed one hundred (100) feet (30.4m) in straight runs and for each aggregate change in direction exceeding one hundred and thirty-five (135) degrees.

 902.2 Traps servicing sinks which are part of the equipment of bars, soda fountains and island counters, need not be vented when the location and construction of such bars, soda fountains and island counters is such as to make it impossible to do so. When such conditions exist, said sinks shall be vented with an approved auto air vent or by means of indirect waster pipes into a floor sink or other approved type receptor.

 903.1 Vent pipe shall be cast iron, Schedule 40 ABS, PVC or other approved materials, except that:

903.1.1 No galvanized wrought ion or galvanized steel pipe shall be used.

903.1.2 ABS and PVC DMV piping installations shall be limited to those structures where combustible construction is allowed.

B.

The following sections are added to Chapter 12 Fuel Piping:

 1201.1 All pipe used for installation, extension, alteration or repair of any gas piping shall be standard weight black steel, except that flex gas piping may be used as an approved material upon issuance of a permit by the City Building Inspector as provided by Section 15.08.140 and provided that the installer is licensed by the manufacturer of the flex gas piping to install such flex gas piping, and the City has on file certification of the installers current license and license number.

 1201.2 All fittings used for installation, extension, alteration or repair of gas piping shall be of black steel.

 1211.5 Ferrous gas piping installed underground in exterior locations shall be protected from corrosion by approved coating or wrapping materials. All horizontal metallic piping shall have at least Twelve (12) inches (.3m) of earth cover or other equivalent protection. Risers shall be metallic and shall be wrapped to a point at least Six (6) inches (152.4mm) above grade.

 1216.1 The following regulations as set forth in this section and in section 1217.0, Required Gas Piping Size, shall be the standard for the installation of gas piping. All natural gas regulations and tables are based on the use of gas having a specific gravity of sixty-five hundredths (.65), supplied at six (6) to eight (8) inches (154.4-203.2mm) water column pressure at the outlet of the meter. For undiluted liquefied petroleum gas, gas piping may be sized for 2500 BTU per cubic foot (23.SW/L) at eleven (11) inches (279.4mm) water column and specific gravity of one and fifty-two hundredths (1.52). Such installation piping, however, from a gas supply line to the first opening inside a structure served shall in no event be less than one and one-fourth (1.25) inches of inside diameter.
