What Is Backwashing a Pool Filter Mean: A Complete Guide for Pool Owners

If you own a pool, you know how important it is to keep the water clean and clear. One of the key components to maintaining good water quality is having a properly functioning pool filter. However, after a period of use, the filter will become clogged with debris and unable to capture more. This is where backwashing comes in.

In this article, we will discuss in detail what backwashing is, how to do it, and why it is necessary for your pool's health.

What is Backwashing and How Does It Work?

Backwashing is the process of reversing the water flow in your pool filter to flush out dirt, debris, and other impurities that have accumulated in the filter. This is necessary when the filter becomes clogged and is no longer able to trap debris effectively.

The process of backwashing works by sending water in the opposite direction through the filter, causing the debris to be released and flushed out of the filter. The dirty water is then sent out of the pool through a waste line or backwash valve.

When to Backwash Your Pool Filter

There is no set schedule for backwashing your pool filter, as the frequency of backwashing depends on several factors, such as the size of your pool, the amount of debris that enters the pool, and the type of filter you have.

However, a general rule of thumb is to backwash your pool filter once the pressure gauge on your filter reaches 8-10 pounds above its starting pressure. This is an indication that the filter is becoming clogged and needs to be backwashed.

How to Backwash Your Pool Filter: A Step-by-step Guide

Backwashing your pool filter is a fairly simple process that can be completed in just a few minutes. Here is a step-by-step guide on how to backwash your pool filter.

Step 1: Turn off the pump

Before beginning the process of backwashing, turn off the pump that circulates water through the filter.

Step 2: Turn the valve to "backwash"

Locate the multiport valve on your pool filter and turn it to the "backwash" position.

Step 3: Turn on the pump

After turning the valve, turn on the pump to start the backwash process. You should notice dirty water flowing out of the waste line or backwash valve as the filter clears.

Step 4: Rinse the filter

After the backwashing process is complete, turn off the pump and move the valve to the "rinse" position. Turn the pump back on for a few seconds to rinse the filter.

Step 5: Return to normal filtration

Once the filter is rinsed, turn off the pump and return the valve to the “filter” position. Then, you can turn on the pump and enjoy your freshly filtered pool water.

Why is Backwashing Important for Your Pool's Health?

Not backwashing your pool filter can lead to several issues, including poor water quality, higher chemical demand, and reduced circulation, which can lead to algae growth and other unwanted contaminants that can reduce the lifespan of your pool.

By backwashing your pool filter regularly, you can keep your pool water healthy and free of debris, extending the life of your pool and making it more enjoyable for you and your family.
