Fixed whirlpool split union

This made a easy fix for my whirlpool bath tub. Top discharge Union nut was cracked. Perfect solution! Just slid old cracked one up out of the way and installed new split one under it.

I am now able to attach a standard hot tub thread pump and eliminate my old custom Hayward pump union that was threaded to just their product.

The folks at Olympia Spa recommended we buy this part because our new Sundance spa failed and this part fixed our leak at the pump. Simple install.
