Abstract
Cleanout conduit valve assemblies for a cleanout conduit may include a vertically oriented valve housing. The valve housing may include a valve inlet end configured to be disposed in fluid communication with the cleanout conduit and a valve discharge end opposite to and generally above the valve inlet end. The valve discharge end may be oriented within a valve discharge plane disposed at a discharge angle of greater than 0 degrees with respect to a horizontal plane. The valve discharge end may have an upper discharge opening side and a lower discharge opening side sloped downwardly from the upper discharge opening side. A valve body may be pivotally carried by the valve housing at the upper discharge opening side of the valve discharge end. Methods of preventing precipitation and runoff on a ground surface from entering a cleanout conduit connected to a sewer service line are also disclosed.
