The Pool Valet Nozzle is manufactured by Paramount Pool Systems. Each hole on the Pool Valet is either 1/4 inch or 3/8 inch. The nozzle comes with 4 partial holes in it. Only one or two are drilled out all the way. The nozzle can be ordered as a blank and it is left to the installer to drill out the proper holes.
Note: Blank nozzles will cause the pump to dead head out if you do not drill out the hole in the nozzle.
