16 Tex. Admin. Code § 9.134
LP-gas piping shall be installed only by a licensee authorized to perform such installation. A licensee shall not connect an LP-gas container or cylinder to a piping installation made by a person who is not licensed to make such installation, except that connection may be made to piping installed by an individual on that individual's single family residential home. A licensee may connect to piping installed by an unlicensed person provided the licensee has performed a pressure test, verified that the piping has been installed according to the LP-Gas Safety Rules, properly tagged the installation, and filed a properly-completed LPG Form 22 with the Safety Division, identifying the unlicensed person who installed the LP-gas piping.
