US Patent 12110674 Self-supporting vacuum plumbing assembly

A vacuum plumbing assembly includes a premanufactured, self-supporting accumulator assembly having an accumulator, a wastewater outlet conduit rigidly attached to the accumulator, an air intake conduit rigidly attached to the accumulator, and a sensor conduit rigidly attached to the accumulator. The wastewater outlet conduit, the air intake conduit, and the sensor conduit extend substantially parallel to one another from their respective first ends to their respective second ends, and are configured with the accumulator as a unit that is pre-manufactured, the unit being substantially rigid and sufficiently self-supporting to be transportable in a peripherally frameless configuration.
