A pipe cleaning vacuum sealing apparatus includes an intra piping sealing frustum. The frustum is generally shaped as a frustum of a circular cone with an interior and exterior surface. The interior surface is adapted to releasably receive a plurality of various vacuum suction sources. The exterior surface of the frustum is adapted to be releasably received by a plurality of configurations of pipe openings. Alternatively, the pipe cleaning vacuum sealing apparatus includes an extra piping system sealing boot. The sealing boot releasably seals at the surface surrounding a pipe and is adapted to releasably receive a plurality of various vacuum suction sources. Embodiments of the pipe cleaning vacuum sealing apparatuses include a plurality of annular engaging rings to enhance sealing, fixed and telescoping suction tubes, and varying embodiments of separation and retainage chambers further including separation and retainage chambers with at least one ingress port.
