Specifier notes are shown in italics and should be deleted from the final document. Generally, all of the manufacturer’s products in this category are listed and the specifier must take care to delete those products not included in the project.

Depending on the relative complexity of the project, the specifier may choose to combine two or more Plumbing Specialties sections into one. The Section number and title should be adjusted to correspond to the CSI MasterFormat^TM

Edit each Article in this Section to suit project requirements.
