Red light on your septic air pump? Don’t let the problem go unchecked. Learn how to diagnose and fix the issue. A septic air pump is an important component of a septic system. It is responsible for adding oxygen to the system to help break down and treat wastewater. Some of the common causes of red lights on a septic air pump include:

  1. Clogs in the chlorinator.
  2. Clogged Septic Diffuser.
  3. Malfunctioning Septic Air Pump.
  4. Low air pressure.
  5. The septic air pump is powered by electricity. Any problems with the electrical system can cause the pump to malfunction and the red light to come on.
  6. The motor is responsible for driving the pump. If it is not functioning properly, the pump will not be able to operate and the red light may come on.
  7. Make sure that the sprinkler pump is functioning properly.
  8. Check the air pressure sensing tube to ensure that it is clear and not obstructed.
  9. Ensure that the effluent distribution piping is not clogged.
  10. A high water level in the aeration tank can also cause the red light on a septic air pump to come on.

If the red light on your septic air pump is illuminated, it is important to address the problem as soon as possible to prevent further issues with your septic system.

Septic Air Pump Red Light: What to Do

Switch off the alarm to stop it from sounding. If your septic alarm goes off, it is important to address the issue as soon as possible to avoid any potential damage to your septic system or property. Here are some steps you can take:

  1. Determine the cause of the alarm. If the alarm is sounding continuously, it may indicate that the septic tank is full or there is a blockage in the system. If the alarm is sounding intermittently, it may indicate a malfunction in the alarm itself.
  2. Inspect the area around the septic tank and pump. Look for any signs of water or sewage on the ground. This may indicate a problem with the tank or the pump.
  3. Check the float switch in the septic tank. The float switch is a device that activates the pump when the water level in the tank reaches a certain point. If the float switch is stuck or malfunctioning, it may trigger the alarm.
  4. If the alarm goes off repeatedly or you are unable to fix the problem, it is best to call a professional septic tank service to diagnose and resolve the issue.
