Abstract
A silt and debris catching apparatus comprises a housing component and a catchment component. The housing component is adapted to fit within a valve box assembly at a depth below a freeze line. The housing component has a field-installable second handle. The catchment component is coupled to the housing component and includes a filter. The filter retains material that enters the valve box assembly.
Claims25
An apparatus for maintaining valve accessibility in a valve box assembly comprising:
- a housing component configured to pass through a first valve body riser and rest on an annular portion of a second valve body riser of the valve box assembly;
- a catchment component comprising a top portion and a mesh portion, wherein the catchment component is adapted to, in the mesh portion, retain material that enters the valve box assembly, wherein the catchment component is adapted to, in the top portion, attach to the housing component;
- and
- wherein the adapted to attach comprises the housing component configured to slidably receive the top portion of the catchment component.
A method for configuring an apparatus for maintaining valve accessibility in a valve box assembly comprising:
- locating a valve box assembly that comprises a first valve body riser, a second valve body riser and a valve box cover;
- removing the valve box cover from the first valve body riser;
- placing a top portion of a catchment component of an apparatus into a slidably receiving portion of a housing component that is configured to provide a path through rigid members;
- dropping the apparatus into the valve box assembly;
- and
- reengaging the valve box cover with the first valve body riser.
