Improved equipment for supporting a length of flexible drainage hose or piping to extend along a substantially uniform gradient that includes the combination of an open ended flexible tubular element or sleeve for receiving and supporting therein the intermediate segment of a selected drainage hose or piping, with a length of cord or line aligned with and carrying the flexible tubular element or sleeve depending therefrom and therealong. The respective ends of the cord or line extend beyond the respective open ends of the tubular element or sleeve for securing the cord or line in sufficiently taut relation and in an orientation to establish a substantially uniform gradient for the supported length of flexible drainage hose or piping. |
