How Does Backwashing Work?
“Backwashing” refers to the cleaning process of a pool’s filter. Backwashing works by reversing the circulation of water. The pool filter picks up dust, dirt, and other particles. These particles can make it clogged and less effective as time goes by. Backwashing reverses water flow through the filter, flushes out dirt and debris, and cleans the pool. Backwashing is very important for keeping a swimming pool clean and fresh. This can cause cloudy, dirty water and complicate the pool’s chemical balance.
Why Should You Backwash Your Pool Filter?
Backwashing a swimming pool filter is a way to clean it and eliminate dirt, debris, and other substances that have grown up in it. Over time, the filter gathers such particles. These particles can clog it and reduce its ability to remove contaminants from the water. When you backwash, you reverse the circulation of water through the filter. This flushes out the dirt and debris that has built up and cleans the filter. You can keep the water in your pool clear and safe to swim in by backwashing the filter regularly and taking care of it appropriately.
Types of Pool Filters
There are 3 types of filters used in any pool. Each type has its pros and cons, and the most appropriate option relies on several elements, such as size, use, and pool maintenance.
1. Sand filters
The most common filter used in pools is a sand filter. It works by passing water through a bed of sand. As the water flows through the sand, the sand traps dirt, debris, and other pollutants. Clean water then flows back into the pool. However, these filters are less efficient than other filters and require more frequent maintenance.
2. Diatomaceous Earth (DE) filters
The most effective pool filters are diatomaceous earth (DE) filters. It uses diatomaceous earth powder to filter water. The powder catches dirt and dust, making an extremely small filter layer that removes even the tiniest particles. It requires less maintenance than the sand filter, but it is more complicated to operate.
3. Cartridge filters
The cartridge filter uses a pleated cartridge to remove dirt and other particles from the water. Cartridge filters are simpler and need less maintenance than sand and DE filters. Cartridge filters do not require backwashing and only need occasional cleanup and a cartridge element replacement. These filters are more costly and less efficient than other filters.
