  • Patent number: 12060702
    Abstract: An accumulator assembly having a wastewater retention tank defining an interior chamber. A fluid level sensor is coupled to the waste retention tank and configured to sense a level of liquid in the chamber. An extraction pipe extends into the chamber and is coupled to an extraction valve. Coupled to the fluid sensor is a controller that is also coupled to the fluid level sensor and to the extraction valve. The controller is configured to open the extraction valve upon receipt of a signal from the sensor. The accumulator assembly also includes an odor mitigation subassembly in fluid communication with the chamber. The odor mitigation subassembly further includes an air displacement port, an odor filter and an overflow prevention device, the overflow prevention device being in fluid communication with the chamber and located downstream of the air displacement port and upstream of the filter.

  • Patent number: 11976736
    Abstract: A backflow prevention device includes a main pipe body extending along a first center longitudinal axis, at least one check valve disposed within the main pipe body, an inlet pipe connected to an inlet side of the main pipe body, and an outlet pipe connected to an outlet side of the main pipe body. The inlet pipe and the outlet pipe extend along a second center longitudinal axis. The first center longitudinal axis is offset with respect to the second center longitudinal axis in a direction perpendicular to the first and second center longitudinal axes. A center of the valve seat of the at least one check valve is offset with respect to the second center longitudinal axis in the direction perpendicular to the first and second longitudinal axes.

  • Patent number: 10837571
    Abstract: A pilot valve controlled mechanical shut-down valve. The mechanical shut-down valve includes a thermostatic motor that effectuates closing of the pilot valve when the temperature of fluid flowing through the shut-down valve is one of greater than a predetermined value, less than a predetermined value, or within a range of predetermined values. As a result thereof, flow through the shut-down valve is stopped.
