If you are replacing an existing bath tub pump, you should replace it with the same or similar
horsepower and amp rating as your existing pump, if you are happy with current forcefulness
of the water coming out of your jets. Check the markings on the pump you are replacing. In
general bathtub pump motors should have 1 HP for every 4 to 6 standard size jets. More
horsepower is not better. Overpowering your jets with too much horsepower could
damage your plumbing, your equipment, or even you! So, it is important to get the
right sized motor for your bath tub. We offer the following horsepower levels:
For retrofitting, you have the option to add screw-on pump unions which glue directly onto 1.5 inch
plumbing. After the unions are glued onto your bath tub’s existing plumbing, the unions screw
directly onto the pump’s suction and return fittings. The included o-rings provide a tight seal.
