Cooling tower overflow drain cap
BACKGROUND OF THE INVENTION 
     1. Field of Invention 
     The invention relates generally to a device that allows overflowing condenser water down the overflow drain, but does not allow carryover of condenser water or makeup water spray to go down the overflow drain. 
     2. Description of the Prior Art 
     Cooling tower overflow drains are left open. The problem with this is that condenser water carryover and makeup water spray go down the overflow drain. This loss of condenser water is costly. This invention eliminates this problem. 
     SUMMARY OF THE INVENTION 
     The invention is a cooling tower overflow drain cap which allows any overflowing condenser water down the overflow drain, but does not let any carryover or makeup spray down the overflow drain. It is the object of this invention to provide an inexpensive device which will allow more efficient use of a cooling tower. That will save on costly water treatment and makeup water.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1 and 2, an embodiment of the cooling tower overflow drain cap is shown. In this embodiment, the cap 1 comprises a stop member 2 and retention leg members 3. The retention leg members 3 must be compressed to be installed into the overflow drain. Installation is complete when stop member 2 is flush to the overflow drain. This invention can be made to fit any size overflow drain. This invention may be constructed of any non-corrosive material. The embodiment of this invention would function to keep a proper level of condenser water in the cooling tower in the on or off modes.
