Drain Assembly

Abstract

A drain assembly includes an outer housing and an inner housing. The outer housing includes a base and a first plurality of sidewalls extending from the base. The inner housing is configured for connection with the outer housing and includes a second plurality of sidewalls, a center hub disposed inward relative to the second plurality of sidewalls, and a plurality of inner portions connected to the second plurality of sidewalls and the center hub. In an assembled configuration, the inner housing is connected with the outer housing such that (i) the inner portions and portions of the base define a plurality of fluid conduits and (ii) the second plurality of sidewalls are offset from the first plurality of sidewalls defining a void, the fluid conduits are arranged in a vortex-shaped configuration, and the void is in fluid communication with the fluid conduits and the center hub.

 fluid is permitted to flow through the hydrostatic valve and out of valve stake when a fluid pressure in the fluid conduits exceeds a pressure threshold; and 
 fluid is inhibited from flowing through the hydrostatic valve when the fluid pressure in the fluid conduits is less than the pressure threshold. 
 
     
     
         8 . The drain assembly of  claim 6  wherein the hydrostatic valve is accessible via the center hub. 
     
     
         9 . The drain assembly of  claim 1  wherein:
 the base includes an outlet that is in fluid communication with a fluid conduit of the plurality of fluid conduits; and 
 a plug is removably disposed in the outlet such that an outer surface of the plug is aligned flush with an inner surface of the base. 
 
     
     
         10 . The drain assembly of  claim 1  further comprising a cover,
 wherein the cover is configured (i) for connection with the inner housing and (ii) to rotate relative to the inner housing. 
 
     
     
         11 . A drain assembly comprising:
 an outer housing including a base; and   an inner housing configured for connection with the outer housing and including a plurality of inner portions,   wherein, in an assembled configuration:
 the inner housing is connected with the outer housing such that the inner portions and portions of the base define a plurality of fluid conduits, and 
 the fluid conduits are arranged in a vortex-shaped configuration. 
   
     
     
         12 . The drain assembly of  claim 11  wherein at least one of the inner portions includes a rib. 
     
     
         13 . The drain assembly of  claim 11  wherein the outer housing includes a plurality of sidewalls that are arranged in a polygonal-shaped configuration. 
     
     
         14 . The drain assembly of  claim 11  further comprising an insert removably disposed in a center hub of the inner housing. 
     
     
         15 . The drain assembly of  claim 14  wherein:
 the insert includes a cone-shaped fluid diverter; 
 the base includes an outlet; and 
 the fluid diverter is configured to guide fluid flowing through the fluid conducts into the outlet. 
 
     
     
         16 . The drain assembly of  claim 11  further comprising a hydrostatic valve and a valve stake, wherein:
