How do I drain the spa and how often should I do this?
All PDC Spas come with drain valves that are located in the base of the spa or as a hose bib on the AdvantagePack. Simply remove the service panel or end cabinet and attach a garden hose to the valve, turn it to flow and release the water from the spa. You must first reduce the temperature setting to the lowest point and disconnect power to the spa at the GFCI breaker before draining. Most manufacturers recommend draining and cleaning your spa no more than 3 or 4 times per year, depending on how frequently you use it and how well you maintain your water. In most cases, this simple process will only take about an hour to accomplish. Details on this procedure can be found in your owners manual. Remember to open the head screw on the filter lid and open the hose bibs to release any trapped air that could “lock” your system’s flow.
