Abstract: A normally open backwater prevention valve for connecting to a sanitary drainpipe. The valve has an inflow end to connect to an upstream part of the drainpipe, and an out-flow end to connect to a downstream part of the drainpipe. There is a main body defining a flow through chamber extending between the inflow and the out-flow ends and a valve seat formed on an upstream side of the main body which faces downstream. A float assembly having opposed floats on opposite sides of the flow through chamber has a check valve assembly including at least a valve member located between the opposed floats. The valve member is sized and shaped to seal on the valve seat, and is operatively connected to the float assembly through a gear box. When the floats are down the valve member is in an open position and when the floats are up the valve member is moved to a closed position on the valve seat. Also provided is an access opening on a top of the flow through chamber, and a removable cover for sealing the access opening.

Abstract: A vent for a building has a cover attached to a base. The base has an aperture permitting gas to pass. A moisture directing means on an underside of the cover directs moisture move under the influence of gravity to fall outside of the aperture. The cover may include a slanted side wall portion, with the aperture positioned with its center displaced from the center of the cover toward the slanted side. The base may include a pair of moisture deflecting features along at least a portion of one of the nonslope sides to prevent moisture flowing along the base from within an area on the base covered by the cover to outside of the covered area at the nonslope sides. The base may also include a water deflecting ridge on its underside positioned between a downslope edge and the aperture to deflect water away.

Abstract: A passive vent for venting a building enclosure having an opening in a roof portion, the vent being adjustable for mounting on roof portions of different slopes. The vent has a base pivotally attached to a vent structure with a pair of pivot joints. The vent structure has a collar attached to a vent body having a cover. At least one gas permeable screen is positioned on the vent body between the cover and the collar. The base comprises a lower attachment structure for attaching the base to the roof portion over the opening. An aperture through the lower attachment structure permits gas to pass in to and out of the opening in the roof portion through the base. A wall including a pair of opposed curvilinear wall sections surrounds the aperture. The pivot joints define a pivot axis about which the vent structure pivots along a range of angles relative to the base. The collar is sized and shaped to overlap portions of the aperture surrounding wall to maintain a continuous wall between the collar and the aperture surrounding wall along the range of angles. At least one securement means secures the vent structure in one of the range of angles relative to the base.

Abstract: A dual function roof vent having a main body having an air passageway extending therethrough and being sized and shaped to fit onto an opening in a roof where the air passageway defines an air to flow path between the interior and the exterior of a building. The air passageway also defines a vent net free flow area. A collar is attached to and extends below the main body, and the collar is sized and shaped to fit through the roof opening. The collar including air inflow gaps, and a fan mount, with an electrically powered fan mounted to said fan mount. The collar air inflow area, including the air inflow gaps, is within about 5% of the vent net free flow area defined by the air passageway.

Abstract: A diffuser baffle for use in an in-line wastewater grease interceptor. The diffuser baffle lies within a grease collecting chamber between the inflow and outflow of a grease interceptor. The diffuser baffle has an open bottom which is sized and shaped respectively to fit into the grease collecting chamber. The diffuser baffle has an end operatively connected to the inflow opening to permit wastewater to flow into the body through the open bottom. The baffle has a downstream end which includes a deflector portion to deflect a wastewater stream in a direction generally into the grease collecting chamber. The body also includes a number of apertures to permit the deflected wastewater stream to pass through the baffle and into the grease collecting chamber, where FOG will separate before waste water exits the chamber through the outlet baffle.

Abstract: An in-line grease interceptor assembly adapted to separate fat, oil, and grease (FOG) out from wastewater mixed with FOG. The assembly has an inlet for receiving wastewater mixed with FOG, an outlet for discharging wastewater after at least some FOG has been separated out from the wastewater, and a chamber hydraulically located between the inlet and the outlet. The chamber has lateral sides, a floor, and an open top, and is adapted to maintain the mixed wastewater in the chamber at a predetermined liquid level located below the open top while accumulating the separated FOG in a layer above the predetermined liquid level. An auxiliary baffle is positioned inside the chamber, extending from a downstream end toward an upstream end of the chamber, between the floor and the open top. The auxiliary baffle has a downstream end, an upstream end, and lateral sides, and defines a first separation section above the auxiliary baffle, and a second separation section below the auxiliary baffle. One or more water directors are also positioned in the chamber to provide a sinuous flow path for the mixed wastewater through the chamber from the inlet to the outlet via the first separation section, and the second separation section. The auxiliary baffle is sized, shaped and positioned in the chamber to substantially block the separated FOG in the first separation section from entering the second separation section. A method of preventing FOG being carried out with wastewater mixed with FOG from a food preparation establishment to a sewer system is also disclosed.

Abstract: An adaptor for a passive roof vent is presented having a base securable to a roof deck and an integrally moulded stepped collar extending from the base on one side for connecting to different air duct sizes which defines a discharge end for an air flow passageway. A central well is defined by the collar adjacent to and below the base and is open towards the other side of the base and has a hinge pin for at least one flapper valve retained in the well below the base. At least one flapper valve, hinged to the hinge pin, pivots about a closed position to which the flapper valve is biased by gravity and an open position in which the flapper valve is opened by air pressure from below within the air flow passageway. The flapper valve remains partially within the well when the flapper valve is open.
