Pool Overflow Drain Heightener

Abstract

The present specification discloses a pool overflow drain heightener that prevents pool water from draining through the pool overflow drain during normal usage, yet permits draining during an emergency overflow event. The pool overflow drain heightener includes a dam basin having an upper rim that defines a mouth configured to be positioned above the desired water level and above the lowest point of the pool overflow drain, such that the water level can temporarily or permanently rise above the lowest point, yet not drain from the pool. Excessive water levels will still be able drain through the mouth, and out the overflow drain, thereby preventing overflow of the pool.

1 . A single piece pool overflow drain heightener comprising:
 a dam basin having at least one wall defining an upper rim and a rear portion and a drainpipe attachment plate mounting portion;   wherein the drainpipe attachment plate mounting portion is located on the rear portion of the dam basin and configured to directly attach to a pool overflow drain of a pool wall;   wherein the at least one wall of the dam basin at least partially define an interior volume with a mouth defined at least partially by the upper rim, the mouth configured to be in fluid communication with the interior volume; and   wherein the pool overflow drain heightener lacks a drainpipe component.   
     
     
         2 . The pool overflow drain heightener of  claim 1 , wherein the at least one wall comprises a front wall, a first sidewall adjacent to and extending from the front wall, a second sidewall adjacent to and extending from the front wall and opposing the first sidewall,
 wherein the front wall, the first sidewall, and the second sidewall define the upper rim and the rear portion.   
     
     
         3 . The pool overflow drain heightener of  claim 1 , wherein the rear portion of the dam basin comprises a dam basin flange that extends laterally outward from and surrounds the periphery of the at least one side. 
     
     
         4 . The pool overflow drain heightener of  claim 1 , wherein the dam basin flange comprises one or more attachment points that facilitate and/or enable securement of the pool overflow drain heightener to a pool overflow drain. 
     
     
         5 . The pool overflow drain heightener of  claim 1 , wherein the one or more attachment points comprise through holes configured to receive a screw or pegs located on the drainpipe attachment plate mounting portion and configured to be pressure-fit inserted into receiving holes located on a pool overflow drain. 
     
     
         6 . The pool overflow drain heightener of  claim 1 , wherein the mouth is configured to be positioned at or above the desired water level and above the lowest point of the pool overflow drain. 
     
     
         7 . The pool overflow drain heightener of  claim 1 , wherein the mouth is configured to be positioned above the highest point of the pool overflow drain. 
     
     
         8 . The pool overflow drain heightener of  claim 1 , wherein the height of the at least one wall is at least 3 inches. 
     
     
         9 . The pool overflow drain heightener of  claim 1 , wherein the at least one wall is a curved surface. 
     
     
         10 . The pool overflow drain heightener of  claim 2 , wherein the front wall, the first sidewall, and the second sidewall for a wedge-shaped surface or a rectangular box shaped surface. 
     
     
         11 . A single piece pool overflow drain heightener comprising:
 a dam basin having a front wall, a first sidewall adjacent to and extending from the front wall, a second sidewall adjacent to and extending from the front wall and opposing the first sidewall, a drainpipe attachment plate, and a dam basin mouth at least partially defined by the front wall, the first sidewall, and the second sidewall, and an interior volume at least partially defined by the front wall, the first sidewall, and the second sidewall,   wherein the drainpipe attachment plate is located on the rear portion of the dam basin and configured to directly attach to a pool overflow drain of a pool wall; and   wherein the dam basin mouth is configured to be in fluid communication with the interior volume, and the interior volume is configured to be in fluid communication with a pool drainpipe when installed, and   wherein the pool overflow drain heightener lacks a drainpipe component.   
     
     
         12 . The pool overflow drain heightener of  claim 11 , further comprising a dam basin flange that extends laterally outward from and surrounds the periphery of each of the first sidewall and the second sidewall. 
     
     
         13 . The pool overflow drain heightener of  claim 11 , wherein the dam basin flange comprises one or more attachment points that facilitate and/or enable securement of the pool overflow drain heightener to a pool overflow drain. 
     
     
         14 . The pool overflow drain heightener of  claim 11 , wherein the one or more attachment points comprise through holes configured to receive a screw or pegs located on the drainpipe attachment plate mounting portion and configured to be pressure-fit inserted into receiving holes located on a pool overflow drain. 
     
     
         15 . The pool overflow drain heightener of  claim 11 , wherein the mouth is configured to be positioned at or above the desired water level and above the lowest point of the pool overflow drain. 
     
     
         16 . The pool overflow drain heightener of  claim 11 , wherein the mouth is configured to be positioned above the highest point of the pool overflow drain. 
     
     
         17 . The pool overflow drain heightener of  claim 11 , wherein the height of the at least one wall is at least 3 inches. 
     
     
         18 . The pool overflow drain heightener of  claim 11 , wherein the front wall, the first sidewall, and the second sidewall for a wedge-shaped surface or a rectangular box shaped surface.
