| 04/18/2016 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | 1. The design currently shows one storage-type water heater and two future tankless water heaters. Clarify how the hot water will be provided to the building at the conclusion of this activity (i.e. when does "future" occur?). Reference: Section 107.2.1, IBC 2012. [Second comment: The currently specified water heater does have a maximum gas input of 180 MBH but it also has a maximum flow rate of 4.5 GPM at a 77-degree Fahrenheit temperature rise. Also, what is the source of the fixture units used to determine the water demand? Based on the 2012 UPC, 15 fixture units would have an 11-GPM demand, not 8-GPM.] [Initial comment: The specified water heater has a maximum flow rate of 9.8 GPM. Show that the hot water demand for the proposed fixtures can be accommodated by the water heater. Reference: Sections 303.2 and 607.1, IPC 2012.] 2. Show how the effective distance from the hot water source to the furthest hot water outlet is to be addressed. The maximum distance shall be no further than 50 feet; see Section 607.2, IPC 2012. [Second comment: The horizontal distance from the water heater to each of the restroom lavatories is approximately 45-feet; include the vertical pipe sections when determining if the developed length of the hot water piping is greater than 50-feet.] [Initial comment: Verify that the developed length of hot water piping from the water heater to the furthest load is no greater than 50-feet. Reference: Section 607.2, IPC 2012.] 3. Comment not addressed. [Second comment: Placing a copy of the initial comment on the drawing does not resolve the issue. Specify the type of backflow prevention device required for each directly-connected appliance that does not have a listed, integral backflow preventer or an integral air gap. See sheet P-4.] [Initial comment: Appliances (e.g. chemical dispensing systems, ovens, etc) to be directly connected to the water supply system that do not have listed, integral backflow preventers or integral air gaps conforming to Section 608.13.1, IPC require backflow prevention. Specify the type of backflow prevention device required for each water connection. (Note that water supply connections to beverage dispensers shall be protected with backflow preventers conforming to ASSE 1022.) Reference: Sections 608.1, 608.3, and 608.16.1, IPC 2012.] 4. Comment not addressed. [Second comment: Comment not resolved. Revise the waste and vent isometric to show the five floor sinks with traps.] [Initial comment: Clarify the installation of the floor sinks as shown on the sewer isometric (i.e. traps?) and coordinate the isometric with the plumbing plan to clearly show which fixtures are connected to the grease waste or to the sanitary waste and to include all of the fixtures shown on the plumbing plan. Reference: Section 107.2.1, IBC 2012.] 5. Comment not addressed. [Second comment: Specify how the contractor is to provide protection for the trap seals.] [Initial comment: Provide protection of the trap seals for all floor drains subject to infrequent use. Reference: Section 1002.4, IPC 2012.] 6. Provide written responses to each comment. Reference: Section 107.2.1, IBC 2012. |
