ProposalsEdit ProposalItem #: 003UPC 2021 Section: 206.0, 309.6SUBMITTER: Phillip H RibbsPHR ConsultantsRECOMMENDATION:Add new text206.0 - D Dead Leg. A section of pipe which contains water that has no flow, does not circulate, remains stagnant, or is infrequently used.309.0 Workmanship.309.6 Dead Legs. Dead legs shall be made as short as possible and shall contain a means of flushing or located in line withdownstream fixtures.SUBSTANTIATION:Dead legs are currently silent in the code and should be addressed to avoid the growth of bacteria in water supplysystems.COMMITTEE ACTION: ACCEPT AS AMENDED BY THE TCAmend proposal as follows:206.0 - D Dead Leg. A section of pipe which contains water that has no flow, or does not circulate, remains stagnant, or is infrequently used.309.0 Workmanship.309.6 Dead Legs. Dead legs shall be made as short as possible and shall contain a means have a method of flushing or located inline with downstream fixtures.COMMITTEE STATEMENT:The modification will clarify the intent of the section in regards to the definition and provisions pertaining to deadlegs.TOTAL ELIGIBLE TO VOTE: 21VOTING RESULTS:AFFIRMATIVE: 18NEGATIVE: 3EXPLANATION OF NEGATIVE:BALLANCO: There was no technical justification submitted to support the change or the modification. I believe the requirement shouldbe rejected. The provisions are very subjective and difficult to enforce even if technical justification was provided.CUDAHY: I agree with the other negative responders - this is a good idea, but very difficult to get into a useable code. Is a vacationhouse one giant dead leg? What about that extra bathroom not being used?FEEHAN: This will cause confusion and will be trouble in the field. There are many dead legs installed for future fixtures.1

Appended CommentsEdit CommentPUBLIC COMMENT 1Code Year: 2021 UPC Section #: 206.0, 309.6Item #: 003SUBMITTER: Michael CudahyPPFAComment #: 1RECOMMENDATION:Delete text without substitutionRequest to reject the code change proposal by this public comment.SUBSTANTIATION:PPFA recommends disapproval of Item # 003. Limiting potential dead legs is a good idea, but very difficult to getinto a usable code. Is a vacation house one giant dead leg? What about that extra bathroom not being used? It's anenforcement nightmare as well. Having a method of flushing is also a good design idea, but would it ever be used?At some point in time, every pipe has no flow, but is not a dead leg.2

ProposalsEdit ProposalItem #: 004.01UPC 2021 Section: 207.0SUBMITTER: UPC Technical Committee ProposalRECOMMENDATION:Add new text207.0 – E –Expansion Tank. A vessel used to protect closed water heating systems from excessive pressure.SUBSTANTIATION:The term “expansion tank” is used throughout the code and the definition is necessary for the enforcement of thepurposes.COMMITTEE ACTION: ACCEPT AS SUBMITTEDTOTAL ELIGIBLE TO VOTE: 21VOTING RESULTS:AFFIRMATIVE: 8NEGATIVE: 13Note:Item # 004.01 failed to achieve the necessary 2/3 affirmative vote of return ballots. In accordance with Section 43.5.2 of the Regulations Governing Committee Projects, a public comment is requested for this proposal. Thetechnical committee will reconsider this proposal as a public comment.EXPLANATION OF AFFIRMATIVE:ADLER: I am amenable to some appropriate modification to the definition. Remember, it is a definition not a code requirement. I simplynoticed that while we have several mentions of “expansion tank” within the Code, there was, in fact, no definition included in the Code,so I sought to remedy.EXPLANATION OF NEGATIVE:AGUILAR: An expansion tank can be used in other systems besides a hot water system therefore the definition should not berestricted to only hot water systems.BALLANCO: The definition is incorrect. It states that an expansion tank is for closed water heating systems only. Yet, Section 608.2requires an expansion tank on a cold water piping system. Additionally, expansion tank is a common term used in the industry thatdoes not require a special definition.BARBATO: This definition restricts “expansion tanks” to water heating systems. Section 608.2 requires an expansion tank in the coldwater distribution system downstream of a pressure regulator regardless of the presence of a water heating system. If the definitionwould read “A vessel used to protect a closed water system from excessive pressure due to thermal expansion” I would agree with theintroduction of the new definition.CUDAHY: Expansion tanks have other uses, the definition is restrictive.DANIELS: The use of expansion tanks is not limited to heat systems.FEEHAN: “Expansion tank” is a common term used in the industry and does not require a definition.MANN, SEWELL: The definition of an expansion tank should not be restricted only to a hot water system.MORENO: The definition should not have the word “heating.”3

NIELSEN: Expansion tanks are not only for “heating” systems.RIBBS: Expansion tank is a common term used in the industry and does not require a definition.SIGLER: The definition is too restrictive as expansion tanks are used in cold water piping systems as well.SMITH: The proposed definition is too restrictive.Appended CommentsEdit CommentPUBLIC COMMENT 1Code Year: 2021 UPC Section #: 207.0Item #: 004.01SUBMITTER: Bob AdlerSelfComment #: 1RECOMMENDATION:Revise textRequest to replace the code change proposal by this public comment.207.0 – E –Expansion Tank. A vessel used to protect closed water heating or cooling systems from excessive pressure.SUBSTANTIATION:The proposed change will address the TC's concern that expansion tanks are not only used for heating systems.4

ProposalsEdit ProposalItem #: 005UPC 2021 Section: 212.0SUBMITTER: Mark FaselViega LLCRECOMMENDATION:Revise text212.0 - J Joint, Press-Connect. A permanent mechanical joint incorporating an elastomeric seal or an elastomeric seal and corrosionresistant grip or bite ring. The joint is made with a pressing tool and jaw or ring that complies with the manufacturer'sinstallation instructions.SUBSTANTIATION:We have discovered that the mechanical attaching grip "or bite" ring is referred to as a grip ring by somemanufacturers and a bite ring by others. The proposed addition of the words "or bite" is for clarification that a PressConnect joint may incorporate a grip or a bite ring in the design. These terms are usually found in the dimensionaldrawings of the fittings. This revision will provide clarification for the Building Official and Installer so there are nomisunderstandings on what may be considered a Press-Connect Joint.COMMITTEE ACTION: REJECTCOMMITTEE STATEMENT:The proposed change is not necessary as it does not strengthen the code.TOTAL ELIGIBLE TO VOTE: 21VOTING RESULTS:AFFIRMATIVE: 21Appended CommentsEdit CommentPUBLIC COMMENT 1Item #: 005Code Year: 2021 UPC Section #: 212.0Comment #: 1SUBMITTER: Mark FaselViega LLCRECOMMENDATION:Revise textRequest to accept the code change proposal as submitted by this public comment.SUBSTANTIATION:The proposed language is necessary and will strengthen the code since it has been discovered that the mechanicalattaching grip "or bite" ring is referred to as a grip ring by some manufacturers and a bite ring by others.
