ABSTRACT:
Drain apparatus drains an evaporative cooler housing by siphon action. The siphoning action is started when a pump which pumps water for cooler pads is turned off, and the water in a conduit flows downwardly and a valve is switched, directing the downwardly flowing water into a chamber disposed over the overflow standpipe in the housing. The water level in the chamber is the water level in the housing, and the down flowing water fills the chamber, causing the water to flow down the pipe and lowering the atmospheric pressure in the chamber to begin siphoning action. At the same time, a check valve at the bottom of the chamber opens to allow water from the housing to flow into the chamber to drain the housing. Several embodiments are disclosed, including embodiments in which siphoning action may be commenced by raising and lowering a drain hose connected to the standpipe.
