Air blower is very loud, surges, or spits water from air injectors.

Safety first: Turn off power before working on the blower or air lines.

• Inspect air intake: Ensure the blower's air intake is not blocked by debris or insulation.
• Drain water from lines: If water is present in the blower or air lines, disconnect the blower and allow water to drain. Some systems have drain points on the air manifold.
• Check check valve: Inspect and replace any faulty check valve that should prevent water from backing into the blower.
• Reposition blower (if needed): Ensure the blower is installed above the waterline as specified by Aquavia to minimize water ingress.
