WORTH, TI X. Members of the City Council City of F.vrt Worth Mrs. McKnight and Gentlemen: the Soperviiing Board of Plumbers in regblar meeting February 24, 1960 reviewed proposed amendments to the Plumbing Ordinance of the City of Fort Worth and, after considerable study and discussion, proposes the attached.amendments to Ordinance #2978, which is the Plumbing Ordinance of the City of Fort Worth. It Is the recommendation of the Board that the Plumbing Ordinance be amended In accordance with these proposed amendments summarized as follows PP 7-5: Permitting only Type K soft copper tubing to be used under con- crete slabs. The ordinance now permits galvanized pipe and Type L copper tubing which has proven very unsatisfactory from the home owners stand- point in that considerable maintenance due to leaks and breaks has been necessary within a short period of time after installation. This amend- ment to this section is recommended by the Home Builders Association, the Associated Mechanical Contractors and Associated Plumbing Contractors. PP 7-10: Permitting the use of plastic tape coating on gas piping and stating specifications for both coal tar coating and plastic tape coating. PP 8-4: Permitting installation of water pipe under concrete slabs by the system known as looping and specifying the method of installation. PP 10-5: Washing machine waste permitted to be recessed in petition walls by one of two methods: (1) the recess for the waste and water connection for. the washing machine shall be open from the floor to the top of the recess not to exceed 4 feet; .or (2) by using a non-corrosive metal recep- tacle whith flanged sides and with waterproof connections, the recess may be enclosed. Also, permitting the installation of dishwashing machines by one of the two following methods: (1) the waste from the machine may be connected by manufacturers' special fitting between the sink outlet and trap of the sink; or (2) the waste may connect to the opening in the garbage disposal , and the connection shall comply with the manufacturers' recommendations. LW DRSECRETARY M&C GO- 43 ORTH, TEX• April 8, 1960 Page 2 PP 12-2: Permits for P-Traps to be used on the installation of bath tubs and allows the use of twin drainage fittings when 2, 3 or 4 bath rooms are installed back to back or in line with each other. PP 12-3: In lieu of lead shower pans, laminated materials are permitted to be used in the installation of shower baths for the lining of the base of the shower stall provided they are manufactured under Federal Specificatbns UU-P-31b or CC-T-191b. PP 14-4: Requiring that temperature and pressure relief valves on hot water heaters be constructed so that they will automatically open when either 1259 per square inch of pressure is reached or the temperature exceeds 210° and the BTU capacity of the temperature relief valve must be equal or greater than the BTU input to the water heater on which it is installed. Attached in the form of an ordinance are the amendments to the present ordinance recommended by the Supervising Board of Plumbers. Under the rules of the Council , this ordinance should not be finally acted upon until the next Council meeting, unless advanced for action by two-thirds of the Council .
