If you own a swimming pool or spa, you know how important it is to keep your pool water clean. A regular maintenance schedule of cleaning and sanitation should be part of your routine.

In this article, we will answer the question What is Backwashing Pool Filter and explain why you should be backwashing your pool regularly.

Understanding Pool Filtration

Before we dive into backwashing, let's first discuss what pool filtration does. Pool filtration removes debris and small particles from your pool water, making sure that it remains clean and safe for swimming. Filtration also helps in balancing the water chemistry and reduces the amount of chlorine or other chemicals required to maintain the pool.

There are three main types of pool filters - sand, cartridge, and Diatomaceous Earth (DE). No matter which type you are using, they all have one job - to keep debris and contaminants out of your pool. A pool filter is essential in maintaining the proper chemical balance of your pool, so it's essential that you understand how it works.

What is Backwashing?

Think of backwashing as "cleaning the filter." Over time, the filter will start to get clogged with debris and small particles. When the filter is no longer working correctly, it's time to backwash. Backwashing is the process of reversing the flow of water through the filter, which dislodges dirt, debris, or other contaminants that have clogged the filter.

When to Backwash

It's essential to know when to backwash, as overdoing it can cause premature wear and tear on your filter, requiring replacement sooner than necessary. The ideal time to backwash is when the pressure gauge on the filter shows an increase in pressure of about ten pounds above the normal operating pressure of the filter. For example, if the normal operating pressure is 20 psi, then when the pressure gauge reads 30 psi or higher, it's time to backwash.

How to Backwash a Pool Filter
