IRC-Plumbing Code Change No.	IRC-Plumbing Section	Change Summary b/t 2015 IRC-P and 2018 IRC-P	Change Summary b/t 2017 FRC-P and 2018 IRC-P	Staff comments	
RP8-15	P2902.5.4, P2904.1.	Modifies Section P2902.5.4 “Connections to automatic fire sprinkler systems,” P2904.1 “General.” The proposed revision clarifies the code by coordinating the requirements in Sections P2902.5.4 with P2904.1. The allowance to omit backflow protection for certain stand-alone systems currently permitted by Section P2904.1 was not previously correlated with Section P2902.5.4, which has caused confusion in applying the code.

Cost Impact: Will not increase the cost of construction.
The proposal will reduce the cost of construction in cases where a backflow preventer would otherwise have been provided because of a misunderstanding of the current code provisions.

RP15-15	P2906.9.1.4
(error)	Renumbers and modifies text of Sections P2906.10 “Cross-linked polyethylene plastic (PEX).” P2906.10.1 “Flared joints.” P2906.10.2 “Mechanical joints.” The Section for "PEX Plastic"
(P2906.9.1.5) should never have been subcategorized under "Solvent cementing" Section P2906.9.1. Like other specific piping material types, "PEX plastic" should have had it's own section like that of Polypropylene (PP), PEX/AL/PEX, Stainless Steel, Press-connect, and PE-RT to name a few.

Cost Impact: Will not increase the cost of construction.

This proposal will have no effect on the cost of construction and only seeks to correct an oversight of organizational numbering.

P166-15, Part II	P2602.1
(IRC)	Modifies Section P2602.1 “General.” Adds Exception to 2602.1. Some jurisdictions do not have state and local laws for private sewage disposal systems. Therefore in those cases, the IPSDC provides regulations for waste disposal. The section language (existing or revised) presents a roadblock for utilizing gray water systems. The exception was added to allow for gray water to be diverted from the sewer or private sewage disposal system so that it can be processed by systems in accordance with Chapters P2910 or P2911.

Cost Impact: Will not increase the cost of construction.
This proposal will increase the cost of construction because additional labor, materials, equipment, appliances or devices are mandated beyond what is currently required by the code. Specifically, where private sewage disposal is not regulated by state and local laws, builders could do anything with sewage. They might not provide a large enough private sewage disposal system or one made of materials having long life. In those situations, there will be the extra cost for properly sized systems and better materials. Possibly there would be some additional labor for a larger installation.

Added text is in conflict with DOH waste deposal regulation Rule 64E-6.  The IPSDC is not part of the FBC

P194-15, Part II	P3007.3.2
(IRC)	Modifies section P3007.3.2 “Sump pit.”  The purpose of this code change is to make the IPC consistent with the IRC where the sump cover is installed not more than 2 inches below grade.

Cost Impact: Will not increase the cost of construction
There is no change to the requirements of this section. This proposal is for correlation purposes only.
