Spa makes a gurgling or sucking noise at the skimmer, especially when jets are on high.

Safety: Avoid running the pump with air being drawn into the system; it can cause cavitation and heater issues.

• Raise water level: Fill the spa so that the water is at least halfway up the skimmer opening on your QCA Spas shell.
• Clean skimmer basket: Remove any debris from the skimmer basket and weir door area.
• Reduce pump speed: If equipped with variable speeds, run the pump on low or medium until water level is corrected.
