Rinsing your bathing suits, and showering without soap, prior to entering your spa will increase the life of your spa water. Depending upon usage, the spa water will need to be changed every 4-6 months or when the water chemical levels become difficult to manage. When changing spa water, if your spa is fitted with JetPaks™. remove all JetPaks™. Clean the JetPod™ areas with a spa surface cleaner. See Spa Shell Care. Clean the plumbing areas on the back of the JetPaks with a spa surface cleaner and a long, soft bristle brush.
