While we have been awarded 33 patents, here are our top ten that we own covering ground-breaking solutions for improving below-grade spaces.
The present invention relates to novel oblong, preferably bilobular, sump containers or reservoir housings for containing sump pump stands and two or more sump pumps. Containers are more narrow, side-to-side, than conventional circular, frustroconical larger volume sump containers, and only slightly longer or wider lengthwise than such conventional standard-size containers. This provides a substantially larger interior integrated oblong cross-sectional floor area for the containment of two or more sump pumps without interference with each other.
The present housings preferably have a top oblong reinforcing rim and a reinforcing bridge connecting the reinforcing rim across the width of said container. The present sump pump reservoir housings also have a two-piece oblong or bilobular cross-section cover which is attachable to the reinforcing rim to enclose the housing. It includes ports for the extension of pump discharge conduits from pumps within the housing through the cover to a discharge area.
An elongate drainage conduit section comprises a channel portion having at least one perforated surface allowing liquid to flow into the channel, and at least one lower surface for directing the flow of water in a lengthwise direction. The conduit further comprises an elongate, movable cover for sealing at least a portion of the top of said channel portion.
An alarm system for a storage hot water heater comprising an alarm housing, power supply leads inserted through the top of a hot water heater tank, a fluid collection pan positioned under the tank, and a fluid detection sensor associated with the pan.
The alarm housing is configured to provide prompt owner/operator notification after only a small amount of fluid is collected in the pan under the tank.
Owner/operator notification can be provided via audible, visual, and/or remote means, such as but not limited to a signal transmitted to a home security device that is relayed to a 24-hour security monitoring network.
Since the alarm housing is hard wired, reliance on batteries is avoided and the system's useful life meets or exceeds that of the associated hot water heater. In addition, the leads never have to be removed from the hot water heater tank and can be made tamper-resistant.
A water-escape conduit connector for use in the exterior above-ground vertical section of a water-discharge conduit having an interior vertical conduit segment communicating with a sump pump container or liner 14.
The water-discharge conduit comprises an upstream segment, between the sump pump liner and the water-escape connector, and a downstream segment between the water-escape connector and the discharge or outlet end of the conduit. The novel water-escape device of the present invention is interposed in the water discharge conduit, at an exterior, above-ground location, to provide an emergency water outlet in the event that the downstream conduit segment becomes sealed against the free discharge of water.
A plastic water-conveying elongate enclosure for confining admitted groundwater adjacent the wall-floor joint around the inner periphery of a basement or other subterranean room. The invention relates to a novel undersurface of the enclosure comprising spaced longitudinal dovetailed or flanged ribs and grooves which provide improved receptivity, distribution and retention of bonding adhesive, used to bond the enclosure to the floor.
A system for encapsulating a crawlspace against the entry of sub-soil water vapor and also against the entry of external ground water from the crawlspace walls and for completely isolating the building from water vapor from the earth.
The present system applies over the floor of the crawlspace (generally a dirt floor but sometimes a poured concrete floor) a continuous durable sealed plastic film barrier layer or laminate. The barrier is extended vertically-upwardly to cover and seal the interior peripheral walls enclosing the crawlspace to an elevation at least slightly greater than the elevation of the ground in contact with the exterior surfaces of the peripheral walls and preferably to the tops of the peripheral walls. This encapsulates the dirt surface of the entire crawlspace against the penetration of external ground water or floor water and also sub-soil water and water vapor onto the surface of the plastic barrier film and into the crawlspace atmosphere.
System for preventing the accumulation of water within exterior foundation areas, such as basement window wells, even under conditions of extreme groundwater flow. The system comprises a combination of an upper horizontal conduit section which extends out through a bore in a basement wall and opens into the dry well area within an exterior basement window well. It has an opposed end which opens at the interior surface of the basement wall, and an elongate, vertical stepped wall panel having a central stand-off conduit section. An opposed vertical seat portions which sealingly-engage the interior surface of the basement wall and form there between the central, vertical, raised or stand-off water-conveying conduit section.
The wall panel extends from an upper location, above the interior opening of the horizontal conduit, to a lower water-drainage location, preferably within a horizontal baseboard water drainage system. This permits the free flow of water from the window well, through the basement wall, and down between the raised or standoff vertical water-conveying conduit section and the wall surface into the water drainage system.
Sump container designed to permit gravity flow of flood water from a basement floor through the cover into the sump container and to permit the pumping of water from the container through a discharge conduit passing through an opening in the cover.
The cover has a transverse opening to receive a discharge conduit for water pumped from the container to an outside drain, a dividing line through the transverse opening and separating said cover into two removable cover sections, and an air-sealed water inlet through the cover to permit flood water to flow into the container while retarding the escape of odor, radon, moisture and pump noise from the container.
A sub-floor water control drainage conduit element and system which minimizes installation labor, materials and time. The drainage conduit element comprises an elongate conduit section which is somewhat hemispherical or somewhat-rectangular in cross-section and has a flat base on floor wall, and a roof wall and/or sidewall. The floor wall is designed to be supported on the top surface of a footing at the wall-footing interface or in an excavation at the base of a wall. The conduit section is open to admit groundwater, such as from the wall-footing interface, and the element contains an upper vertical wall portion which is designed to extend above the basement floor surface and is spaced from the basement wall to provide a wall drain gap down to the conduit section.
A drain system for draining water to a ground surface includes an extension pipe and a drain outlet. The extension pipe is capable of being disposed underground below a grade of the ground surface. The drain outlet is communicably coupled to the pipe. The drain outlet has a base and a cover section. The base has a drainage surface, a drainage end and an inlet section. The drainage end forms at least one effluent drainage hole therein. The inlet section is adapted to be coupled to an outlet of the extension pipe. The drainage surface is disposed for guiding effluent from the inlet section to the drainage end. The cover section is coupled to and covers the base. The base is configured for founding the drain outlet to the ground, when the drain outlet is coupled to the pipe disposed underground. The at least one drainage hole is located substantially at or above the grade allowing substantially unimpeded affluent discharge from the inlet section through the at least one drainage hole to the ground surface.
