Why Is My Pool Filter Bubbling?

As a pool owner, experiencing a bubbling pool filter can be concerning. If you’re wondering why your pool filter is bubbling, there are a few possible causes. In this article, we will explore the reasons why your pool filter may be bubbling and how to troubleshoot the issue.

Possible Causes of a Bubbling Pool Filter

1. Air Leak in the System

One potential cause of a bubbling pool filter is an air leak in the plumbing system. The air can enter the filter through a crack or gap in the pipe, valve, pump, or any other part of the system. When air is present in the pool filter, it bubbles back out as the water is pushed through the filter.

2. Low Water Level in the Pool

Another potential cause of a bubbling pool filter is low water level in the pool. If the water level drops too low, the skimmer and main drains can suck in air, which can cause the pool filter to bubble.

3. Clogged Air Bleeder Valve or Gauge

A clogged air bleeder valve or gauge can also cause a pool filter to bubble. If the air bleeder valve or gauge is clogged, air cannot escape from the system, causing it to build up in the filter and bubble back out.

4. Dirty or Clogged Pool Filter

A dirty or clogged pool filter can also lead to bubbling. When the filter is clogged, the water cannot pass through it properly, which can cause it to bubble back out.

5. High Pressure in the Pool Filter System

High pressure in the pool filter system can also cause bubbling. Excessive pressure can cause air to build up in the system, leading to bubbles in the pool filter.

Troubleshooting Steps

1. Check for Air Leaks

Start by checking for air leaks in the system. Inspect the pump, filter, valves, and connections for any cracks or gaps. If you find any, seal them immediately to prevent air from entering the system.

2. Check Water Level in the Pool

If you suspect that low water levels are the cause of the problem, add water to the pool until the level is back to normal.

3. Clean or Replace the Air Bleeder Valve or Gauge

Clean or replace the air bleeder valve or gauge to ensure that air is able to escape from the system.

4. Clean or Replace the Pool Filter

If the pool filter is dirty or clogged, clean or replace it to ensure proper filtration. This will help prevent bubbles from forming in the system.

5. Check the Pressure in the Filter System

If the pressure in the filter system is too high, you may need to adjust the pump or clean the filter to reduce pressure. This will help prevent bubbles from forming in the pool filter.

Prevention Tips

1. Regularly maintain and clean your pool filter to keep it running properly.

2. Keep your pool water at the proper level to prevent air from entering the system.

3. Periodically inspect and repair any cracks or gaps in the pool plumbing system to prevent air leaks.

4. Keep the air bleeder valve or gauge clean to ensure that air is able to escape from the filter system.

5. Maintain proper pressure in the filter system to prevent air from building up and causing bubbles in the pool filter.

Conclusion

A bubbling pool filter can be a frustrating problem to deal with, but it can be resolved with proper troubleshooting techniques. By identifying the potential causes of a bubbling pool filter and taking the necessary steps to prevent and address these issues, you can keep your pool filter running smoothly and your pool water crystal clear.
