Section 6-77-114 - Service lines: general requirements for connections to main piping(a) Location. Each service-line connection to a main must be located at the top of the main or, if that is not practical, at the side of the main, unless a suitable protective device is installed to minimize the possibility of dust and moisture being carried from the main into the service line.(b) Compression-type connection to main. Each compression-type service line to main connection must: (1) Be designed and installed to effectively sustain the longitudinal pull-out or thrust forces caused by contraction or expansion of the piping, or by anticipated external or internal loading; and(2) If gaskets are used in connecting the service line to the main connection fitting, have gaskets that are compatible with the kind of gas in the system.[Eff ] (Auth: HRS § 269-6) (Imp: 49 C.F.R. §192.367, OCT 1, 1990)
