SpaGuts P/N: 40-200-1060
A small number of spas have been built with mismatched plumbing. Usually the water intake and outlet sizes are the same, either 1.5 or 2 inches but in a small number of spas, one is 1.5 inches and the other is 2 inches.
Also, sometimes people need to adapt a spa component (pump,
controller, blower) to fit a different size of plumbing.
