Causing Air Bubbles in My Pool?

Having a pool in your backyard is a luxury many dream of. The shimmering water, the joyous splashes, and the cool respite on hot days—it’s an oasis right at home. But what happens when unexpected air bubbles start to appear, disturbing your pool and the serene environment?

What Might Cause Air Bubbles in Your Pool

When envisioning the serene ambience of a pool, one typically imagines calm waters reflecting the sun, not aggressive bubbles shooting from the pool’s returns. So, when these bubbles appear, it’s understandable to question their origin.

How Your Pump and Filter System Operate:

  1. Water Intake: Your pump draws water from the pool’s skimmers and main drains.
  2. Initial Filtration: Water first encounters the strainer pot which filters out major debris.
  3. Impeller Push: The water, post strainer pot, is driven towards the filter by an impeller.
  4. Main Filtration: Depending on your setup (sand, cartridge, or D.E. filter), the water is cleansed of dirt, debris, and potentially harmful bacteria.
  5. Final Flow: After filtering, the water might pass through heaters or salt chlorine generators, finally re-entering the pool via return jets.

Causing Air Bubbles in My Pool?

Bubbles in your pool typically indicate that air is being drawn into the suction side of the pump. This often arises during the initial pool setup or after maintenance activities.

Pinpointing the Culprits Behind Air Bubbles

Air being introduced into your pool system can stem from various factors. Let’s delve into the most common culprits:

  • Pool Water Level

If the pool’s water level drops too low, the skimmer might introduce air into the pump/filter system. The recommended water level is halfway to three-quarters up the skimmer. And a special note for fiberglass pool owners: it’s crucial never to drain your pool completely, as it can void warranties and potentially damage the pool structure.

  • Strainer Pot Lid Issues

An improperly secured strainer pot lid can become an unintended entry point for air. Ensure the following:

  1. The lid is securely fastened.
  2. The O-ring beneath the lid is present, undamaged, and correctly seated.
  3. No obstructions like dirt or grit hinder the lid from sealing.
  • Pump-Valve Union Alignment

The fitting between the pool pump and the valves, known as the union, is often where issues arise. Regular maintenance can lead to misalignments or disruptions. Always ensure:

  1. The O-ring within the union is present, undamaged, and correctly seated.
  2. No obstructions prevent the union from achieving a full seal.

Do you still see air bubbles in your pool?

If you’ve examined the aforementioned factors and the problem persists, it might point towards more significant issues like a leak in the plumbing on the suction side. Such issues, especially if they involve the main drain or skimmer line, might require professional intervention. Remember, regular maintenance and vigilance can prevent such problems, ensuring your pool remains your backyard’s sparkling gem.
