20140109988 | DRAIN LINE ACCESS DEVICE - A drain line access device is provided for flushing HVACR drain lines. The device includes a main body having input and outlet connection ports on opposite ends for inline installation to a drain line, a flapper assembly sized and configured for seated placement in an interior cavity of the main body, and a removable top cover. The flapper assembly includes a flapper holder, a flapper, a flapper seat, and a spring hinge for rotatably urging the flapper into the normally raised position. An injection port is provided on the top cover for delivering a flow of pressurized gas or liquid for flushing out a clog in the drain line. In operation, delivery of pressurized gas or fluid into the drain line forces the flapper against the flapper seat, thereby sealing off one of the respective ends of the main body and directing the pressurized gas into the drain line. | 04-24-2014 |
20140338758 | DRAIN LINE ACCESS DEVICE - A drain line valve device is provided for flushing HVACR drain lines. The device includes a main valve body having inlet and outlet connection ports on opposite ends for inline installation to a drain line (between the condensation producing source and drain discharge). The device includes a removable top cover and an adapter that is sized and configured for insertion into the interior cavity of the main body and fitted receipt within the inside of one of the input or outlet ports. The adapter allows for connection of a pressurized gas or liquid flow source for clearing clogs in the drain line, or a vacuum source, as well as pouring of a liquid clog-cleaning product into the drain line. One embodiment of the device includes a main valve body having one connection port for connection with an auxiliary outlet of a drain pan. An overflow safety switch is supported by the top cover in the interior cavity of the main valve body for detecting a clog in the drain line. | 11-20-2014 |
20150059868 | HOSE ATTACHMENT DEVICE FOR CLEARING DRAIN LINES - A hose attachment device for use in combination with a source of pressurized gas or liquid for clearing HVACR drain lines. The device includes a cap having an interior cavity extending from an open bottom end that is sized for engaged receipt of an open-ended drain line extension. One embodiment of the device includes a hose extending through the top of the cap and having a fitting at the proximal end of the hose (extending from the top of the cap) that is sized for attachment to the pressurized source. A valve fitting at the distal end of the hose is sized for engaged receipt of a male valve stem, such as a Schrader valve. Another embodiment of the invention includes a valve fitting extending through top of the cap. A further embodiment of the invention includes an upper component and a lower component forming the cap, wherein the upper component is securable to a nozzle of a garden hose and the bottom component is securable to an open-ended drain line extension. | 03-05-2015 |
