Why Does My Pool Filter Spit Out Dirt?

If you’re a pool owner, then you know that keeping your pool clean is an absolute must. However, what do you do when your pool filter starts spitting out dirt instead of cleaning the water? It can be frustrating and confusing, but luckily there are a few reasons why this may be happening.

In this article, we will discuss the five main reasons why your pool filter may be spitting out dirt and how you can fix it.

1. Backwashing

The first reason why your pool filter may be spitting out dirt is due to backwashing. Backwashing is when you reverse the water flow through your filter to remove any debris or dirt that has been collected. However, if you backwash too frequently or for too long, you may end up pushing the dirt back into your pool.

Solution: To fix this issue, make sure that you are only backwashing your pool filter when necessary and do not exceed the manufacturer's recommended time frame. You can also add a clarifier to your pool water to help gather any debris that may have been pushed back in.

2. The Wrong Size Filter

The size of your pool filter is crucial to ensuring that it can handle the amount of water in your pool. If your filter is too small or the wrong type for your pool, then it may not be able to effectively clean your water, which can result in dirt being spit back out.

Solution: Make sure that you have the right size and type of filter for your pool. You can consult with a professional pool technician to help determine the appropriate size and type of filter for your pool.

3. Dirty or Clogged Filter

A dirty or clogged filter can also cause dirt to be spit back out into your pool. When your filter is dirty, it can’t effectively clean your pool water, which can result in dirt and debris being pushed back into your pool.

Solution: To fix this issue, make sure that you are cleaning or replacing your filter regularly, as recommended by the manufacturer. You can also add a flocculant to your pool water, which will help gather any debris or dirt that may have been spit back into your pool.

4. Poor Water Chemistry

If your pool water chemistry is unbalanced or incorrect, then it can cause your filter to work improperly, resulting in dirt being spit back out into your pool. pH levels that are too high or too low, as well as high levels of total dissolved solids (TDS), can all result in a poorly functioning filter.

Solution: To fix this issue, regularly test your pool water and adjust the chemicals accordingly. You can also use a pre-filter before adding water to your pool to help remove any impurities.

5. Broken or Damaged Filter Parts

If parts of your pool filter are broken or damaged, it can cause dirt to be spit back out into your pool. Cracks or holes in the filter or damaged filter media can result in a filter that is functioning poorly.

Solution: Check the parts of your filter regularly and replace any that are broken or damaged. You can also consult with a pool technician to ensure that your filter is properly installed and functioning correctly.

In conclusion, spitting dirt is a common issue with pool filters that can be caused by a variety of factors. By properly maintaining your pool filter and balancing your water chemistry, you can help minimize this issue and ensure that your pool stays clean and clear all season long.
