Flood control valve assembly

A flood control assembly disposed in fluid communication with a drain pipe, said assembly comprising:

• a) a housing connected to the drain pipe and comprising a substantially elongated hollow interior terminating at oppositely disposed, open, outer and inner ends,
• b) a head assembly removably secured within said outer end of said housing and including a hollow interior and open proximal and distal ends,
• c) said head assembly including a valve seat fixedly mounted thereon and removable therewith relative to said housing, said head assembly, said valve seat and said outer end collectively defining at least a portion of a flow path through said housing,
• d) a chamber connected to said housing and including an open interior disposed in fluid communication with said hollow interior and in spaced relation to said flow path,
• e) a valve member formed of buoyant material movably contained within either said housing along said flow path or within said open interior of said chamber, substantially removed from said flow path,
• f) a retainer assembly connected to said housing in at least partially supporting relation to said valve member, said retainer assembly disposed to retain said valve member out of said flow path during normal flow conditions,
• g) said valve member disposable into and out of sealing engagement with said valve seat dependent upon direction of liquid flow along said flow path,
• h) said chamber being at least partially structured to facilitate travel of said valve element from said open interior into said hollow interior of said housing,
• i) said chamber including at least one interior surface extending from said open interior of said chamber to said hollow interior of said housing and oriented to direct said valve member from said open interior into said flow path, and
• j) said chamber disposed laterally outward from said housing and including an open face contiguous to both said open interior of said chamber and said hollow interior of said housing, said open face being vertically oriented in substantially parallel relation to the length of said housing and sufficiently dimensioned to allow passage of said valve member and liquid flow therethrough and between said open interior and said path.
