Air blower runs but very little air comes from air injectors.

Safety first: Turn off power before accessing blower plumbing.

• Check air intake: Ensure the blower intake is unobstructed.
• Inspect air lines: Look for kinks or low spots where water may collect. Correct routing if necessary.
• Purge water: Run the blower in short bursts with jets on to help clear water from lines.
• Verify check valve orientation: Ensure any air check valves are installed in the correct direction of flow.
