PROPOSED AMENDMENTS TO 1979 UNIFORM PLUMBING CODE . . Section ·20.3 -ts a completion of the section. in the Uniform Plumbing Code en.titled "Violation and Penalties." The Plumbing Code has blanks where the actual penalty provision would be contained and we have merely filled in the blanks with: 11a fine not to exceed $200 per day for each day that the violation of this code occurs.11 Secondly, the third paragraph the Uniform Plumbing Code, as.adopted, Indicates that if work is not commenced within 120 days, the permit shall become void. We have changed this in our amendment.to read 180 days, due to the fact that some people are not able to start the construction project within four months after being issued a permit due to the fact that there may be budget problems, weather problems, or design problems. Therefore, extending it for another 60 days would give the permit holder a more equitable chance to start the work. Section 20.9 -of the Uniform Plumbing Code states that: "Not i fl cat I on sha 11 be given to the Bui 1 ding Inspector not less than 24 hours prior to the work to be inspected.st However, we have established as a goal for this department, to respond within four hours of the time we receive the inspection request. Subsequently, we changed the code from 24 hours to four hours~ I think this is in the best interest of the construction community inasmuch as an inspection can be made In the same day that the plumbing work is finished. Section 104(a} -ts the definition of cesspool. cesspool has been deleted throughout the Uniform Code because the state does not allow cesspools. allusions to cesspools are contradictory to state The term Plumbing Subsequenfl y, law. Section 117(i) -was rewritten to define a s~pt•c tank and to delete the terminology seepage pit. Seepage pit and cesspool are considered to be the same thing and once again, are contrary to state 1aw. Section 120(b) -is the definition for seepage pit and it has been deleted from the code since it is in conflict with state law. Section 204 -was rewritten to be less restrictive; i.e., 4 pound original requirements--2¼ pounds per square foot is revised requirement. --... . . ._) . ' .. Proposed Amendments to 1979 Uniform Plumbing Code October 19, 1981 Page 2 ~- Section 318 -entitled "Inspection and Testing," Section 1,. Sub-section(b) "Advance Notice,.11 was rewritten to reduce the time necessary.for notification from 24 hours to four hours; once again providing more service to the community. Section 401(a) -was written essentially to drop the restriction of ABS or PVC drainage piping to residential construction not mor~ than two stories in height. 1 Section 503(a) -was es·sentially the same as the preceding comment where ABS or PVC installations being limited to residential con- struction not more than two stories in height were deleted. The thought of the board on this issue was that if PVC is an acceptable usage in residential occupancies of two stories or fess, then we should be able to allow it for drainage_ and vent systems in all occupancies in excess of two stories as well. Section 604(a) -has to do with Indirect waste receptors. The original code stated that no trap for any clothes washer stand- pipe receptor shall be installed below the floor. It shall be roughed in not less than six inches and not more than eighteen Inches above the floor. That was changed to read: "It shall be roughed in not more than six inches above the floor." Section 614 -ts entitled "Special Venting for Island Fixtures." The last sentence was added, which states, "A mechnical vent system may be used." - Section 70l(b) -"Traps Required." The section was deleted which stated that "Three lavatories immediately adjacent to each other in the same room could have the same trap."· ·Also, the last sentence was added once again to provide for ease of cleanout when necessary. Section 70l(d) -The last two sentences were added: "Measuring from top of floor to inner edge of vent, the horizontal branch ts not to exceed three feet." This was added for._clarification. Numerous plumbers were having difficulty wtt·h~the actual measurement, and the board felt that this addition would clarify that for the plumbers. Section 706 -The last sentence was added and states: 11 ••• need not be vented if within fifteen feet and if a branch enters the vented 1 ine above the floor 1 ine at the vented l ine.11 -· . ••'f '\ • . *"' ...... ' . ' ' Proposed Amendments to 1979 Uniform Plumbing Code October 19, 1981 Page 3 Section 708 -originally stated: "Interceptors, including grease, oi.l, and sand interceptors, etc., st,al 1 ·be provided when, in the. judgment of the admin.istrative authority, they are necessary for the proper handling of liquid waste containing grease, flammable wastes, sand, solids, etc. This was rewritten to say: 11 1t shall be provided for the proper handling.11 The board felt that the administrative authority should not have to hea~ every case, because it was their consensus that interceptors should be provided. Section 711, Sub-section(a) -The portion regarding grease interceptors was rewritten in its entirety that it might more closely correspond with the last Plumbing Code which was adopted by the City of Lubbock. This also addresses (b), (c), (d), (e), as we 11 as the minimum rate of flow for design, and (f). It was the board's feeling that the design criteria that was in the original City of Lubbock Plumbing Code was the best design criteria currently available for the City. Subsequently, they opted to adopt the previously- existing system in design criteria. Section 713 -was added to the Code in order to provide for a · design that would be acceptable with Section 712. Section 714 -also was added to the Code in order to clarify the instances during which this type of interceptor or trap was required, and who had approval authority. Section 802{i) -deletes reference to the use of bituminized fiber pipe Joints. Bitumlnized piping is no longer allowed under the Uniform Plumbing Code. Section 1002{b) -adds a sentence at the end of the paragrapn stating: 11 lf an on-the-premise inspection cannot be made, then "· a reduced pressure backfill prevention assembly shall be provided which is equa 1 to or better than a Watts 900 •• -~Watts is a brand name supplied for comparison purposes, only.}'- Section 1003{h & t) -Both of these sections have the same sentences added in order to preclude cross-connections with non-potable water distribution points to the City's potable water system. ·-· Proposed Amendments to 1979 Uniform Plumbing Code October 19, 1981 Page 4 Section 1004(d) -was rewritten to exclude any prev·lously used pipe from being allowed for potable wat~r system. Previous to this amendment, water pipe which had been used previously in a potable water system could be used once again in a potable system. It was the consensus of the board that there is no way to tell whether or not a pipe has been used for potable or unpotable, water, and that, it would be better just to eliminate the option. r'I' Section 1007(e) -was rewritten to delete the use of hard- drawn copper piping which is not available and not in production at this time. Section 1008 (b), (c), & (d) -were rewritten•-(b) to a11ow water surface pipes to be laid in the same trench with twelve inches of separation; (c) to eliminate the useab11ity of ferrous piping under slab; (d) t~ require any portion subsequent to (c) above would requi-re a test inspection and approval. In most cases a test is not required for under- slab piping; but where there is a Joint, the board felt it was necessary to ensure that the system is water tight. Sect ion 1101 (d) -was changed from 200 1 . to 100' to allow for the occupant/owner of the property to apply for a septic system from the Health Department; whereas before, the 200' was substantia11y more restrictive. Section 1104 -was deleted because it pertains to private sewage systems and the City of Lubbock does not-control private sewage systems. Section 1107(a) -The last sentence of the second paragraph was added to more clearly identify placement of the cleanout· after final grading and lawn installation and landscaping was weeded. ..·- Section 1108 -was deleted because Section 1008 covers this information. Table 11-1 -deletes references to seepage pits and cesspools which are not allowed. They are also part of private sewage systems and the City does not regulate them. -..,,.~ . " .. . , • • Proposed Amendments to 1979 Uniform.Plumbing Code October 19, 1981 Page 5 Section 1206(c)(2) -the second paragraph was changed to require fifteen ln.ches of mercury to be· used for tes.ting, rather than only ten Inches. The thought of the board was the ten inches of mercury could not supply a sufficient amount of pressure to adequately test the Joints. Section 1213(9) -"lnstal lation of Gas Pipi,ng,11 was modified with the ~dditlon of "On single structures, a union shall be installed at each penetration." Section 1213(n) -This section was deleted as it was the requirement for a number of fifteen copper tracer wire to be installed with an attached two nonmetallic underground gas piping. The board felt this requirement was not reasonable, seeing that we know the point at which the plastic.pipe entered the ground from. the gas meter in the street, and there always is a direct line from the meter to the house. Section 1214(a)(5) -was modified to exclude the use of aluminum alloy connectors. Secdon 1218(a) -Deleted the sentence referring to undiluted liquified petroleum gas piping which may be sized for 2500 BTU 1s per cubit foot. This is not applicable to the Lubbock area. Appendix 1 -refers to the same gas piping sizing for undiluted liquified petroleum. Section 2 -states that ·all IAPMO Standards contained within the Uniform Plumbing Code, 1979 Edition, be and are adopted. We be.1 ieve that it is a specific requirement in order that we .adopt the installation standards of this document. ..-.
