Abstract: A flash pan is adapted for collecting and distributing water infiltrating a building at an access opening. The flash pan includes a low-profile base designed to reside beneath the access opening. The base has opposing longitudinal inside and outside edges, opposing lateral end edges, and top and bottom major surfaces. A plurality of feeder channels are formed with the top major surface of the base, and extend from the inside edge towards the outside edge. A longitudinal collection channel is formed between the inside and outside edges of the base. The collection channel communicates with the plurality of feeder channels for receiving water collected by the feeder channels. A drain channel communicates with the collection channel, and extends outwardly towards the outside edge of the base. Water collecting in the feeder channels flows to the collection channel, and is distributed away from the base through the drain channel.
