(A) General. Every supplied plumbing fixture, piece of plumbing equipment, all piping, and fittings required under this subchapter shall be installed in accordance with the requirements of the Plumbing Code of the city and shall be maintained in a safe and sanitary working condition, free of cross-connections and siphonage between fixtures. Unaltered existing plumbing which conformed to the applicable laws in effect at the time of installation may continue in use, provided that it is maintained in a safe and sanitary working condition, is free of cross-connections and siphonage between fixtures, complies with § 151.031, and is not dangerous to life, health, safety, or public welfare.
(B) Application. This subchapter shall apply to existing plumbing systems as described in this section.
(C) Alteration or repairs. Alterations or repairs may be made to any plumbing system without requiring the existing plumbing to comply with all the requirements of this chapter, provided such alteration or repair work conforms to that required for a new plumbing system. Alterations or repairs shall not cause an existing plumbing system to become unsafe or adversely affect the performance of the plumbing.
(D) Additional loads. Where additions or alterations subject parts of existing system to loads exceeding those permitted herein, such parts shall be made to comply with the current requirements in the Plumbing Code of the city for new structures and systems. This is not meant to imply that the remaining portions, left unaltered, shall be made to be upgraded due to such partial upgrading of deficient portions.
