Mission Statement: To provide public infrastructure, facilitate development, and deliver services that protect and enhance the lives of the people of Kern County. Different size lines provide dramatically different flow rates. In this example, when we talk about the “whole” plumbing water system design, think that PLUMBER will perform for you: In the video’s example, there are 4 residential units per building’s floor and each building has 4 similar levels.

Specifications of "The American Society for Testing Materials" (ASTM). endstream endobj startxref As an example the DEP sizing table sinks, dishwashers, and washing machines are attributed a fixture count of 4. Therefore an 1 1/4″ line provides almost 77% more gallons per minute than a 1″ line.The gallon per minute calculations on the DEP sizing table are also based upon some other vital assumptions. h�bbd``b`��W��a$�t��D1 �� �J��@D\�H��/Az�&�3N�` ��% 202-2 Number of Customers (See Water Supply Requirement Chart, Plate W-5). C-502 or C-503 2-1/2" and 4” national standard threaded connections as required. In many cases this results in no ill-effects, as the NYC DEP sizing table is very conservative.
