Spa pumps are essential pieces of equipment used for hot tubs or spas. They are used to draw water into the filtration system of the spa where the water is pushed through a heater, filter, as well as spa jets before it's allowed into the spa again. Although spa pumps are designed to last for several years with regular use, the gadget may start experiencing frequent operation issues or breakdowns, and you will be required to repair or replace it depending on the problem.
