Where is Rinse on Pool Filter?

When it's time to maintain your pool filter, you may wonder where the rinse setting is located. This is an essential step in cleaning your filter, as it ensures that all the debris and impurities are removed from the system. In this article, we'll take a closer look at where the rinse setting is on a pool filter and why it's important to use it.

Understanding Your Pool Filter

Before we dive into the specifics of finding the rinse setting, it's important to understand how your pool filter works. There are three main types of pool filters: sand, cartridge, and diatomaceous earth (DE). Each type of filter has its unique way of cleaning your pool water, but they all rely on the same basic principles.

Pool filters work by trapping tiny particles and debris as water flows through them. Over time, this trapped matter builds up and creates a blockage. This can make it harder for water to flow through the filter, which can reduce the effectiveness of the system. That's why periodic cleaning is essential for keeping your pool sparkling clean and clear.

What Is the Rinse Setting?

Now that we know why pool filters need to be cleaned, let's focus on the rinse setting. This setting is often labeled as "rinse" or "backwash rinse" on the control valve of your pool filter. When you activate the rinse function, water flows through your filter in the opposite direction to dislodge any trapped debris.

The purpose of the rinse setting is to remove any leftover particles or impurities from your filter. This ensures that your filter operates at optimal efficiency and helps to prolong its lifespan. Neglecting to use the rinse function can lead to clogged filters, which can damage the system, reduce its lifespan, and even cause dirty or cloudy pool water.

How to Find the Rinse Setting

Finding the rinse setting on your pool filter will depend on the type of filter you have. Here's a breakdown of what you need to know for each type of filter:

Sand Filters: The rinse setting is often located next to the backwash setting on the control valve. Look for a lever or knob that moves back and forth to switch between the two settings.

Cartridge Filters: The rinse setting is usually located on the multiport valve. Look for a label or instructions on the valve that indicate where the rinse function is located.

Diatomaceous Earth Filters: The rinse function is generally located on the multiport valve or clamp band. Look for a label or knob that specifically says "rinse" or "backwash rinse."

Once you've located the rinse setting on your pool filter, you're ready to start cleaning.

Using the Rinse Setting

To use the rinse setting, follow these steps:

1. Turn off the pump and close the skimmer valves.

2. Set the filter wheel to "rinse" or "backwash rinse" depending on your filter type.

3. Turn on the pump and let it run until the water in the sight glass or valve discharge is clear.

4. Turn off the pump and set the filter back to its original position.

By following these steps, you'll be able to effectively remove any debris that's been trapped in your filter. This will help to improve the performance of your filter and maintain the crystal-clear water in your pool.


The rinse setting is an essential step in cleaning your pool filter. It ensures that all debris and impurities are removed from your filter, which improves its efficiency and prolongs its lifespan. By following the steps outlined above, you'll be able to locate and use the rinse setting on your pool filter effectively. Regular use of the rinse setting will help to keep your pool sparkling clean and refreshing all summer long.
