I recently bought this tub used from a private party and the Moto massage doesnt work. It appears that the small tube that runs to the moto massage has been disconnected in the equipment compartment and someone stuck a screw in the end of it. This same person has installed a circulation pump that is not a Watkins pump. Is there a port for this to connect to on the factory pump which is not on the circulation pump installed in my spa?

Post photos - overall views of the stuff in question... eg NO close ups of the end of a hose with a screw.

Cant determine anything with verbal description of this.

The tube is normally connected to a nipple that sticks out of the 3/4" 90 degree elbow between the circ pump and the heater, but that is not your problem...that tube does not connect to the blue tube on the moto.

You probably just need to replace the moto-massage jet. If you take it out, hold it by the jet end and see if the 'vertibrae' pieces hang down straight and are loose. If it has a bend to it then it won't work.

You also might try removing the filters. These jets demand good head and bad filters will cause them not to work properly.

I cleaned the filters and replaced the Moto jet and it works!
