The Importance of Maintaining Your Swimming Pool Filtration System

An important aspect of swimming pool maintenance in Atlanta is properly caring for the pool's filtration system. If the filtration system is unable to work effectively the pool is basically rendered useless. Here's what you need to know about your pool's filtration system, why it needs to be maintained, and how you can do that to ensure it keeps running smoothly.

Problems with Neglected Filters

Perhaps the most noticeable problem of a neglected filtration system is murky water. The appeal of cooling off with a dip in the pool is quickly gone when the water isn't crystal clear. Even if you keep the pool water chemistry correct, you can still end up with murky water if the filter is dirty or doesn't fit properly. Another problem of filter neglect is that it will begin leaking. The housing may need to be repaired or replaced to prevent leaking through the filtration system. A filter in need of repair may also allow debris to be washed back into the pool. If the system doesn't work properly because of neglected maintenance, you're in danger of not only exposure to impurities, but the chemical balance could get off, which could be dangerous for your pool and those swimming in it. That's why it's such an important aspect of swimming pool care in Atlanta.

Basic Filter Types

There are three basic types of filtering systems. These are sand filters, cartridge filters, and diatomaceous earth filters. Understanding the basics of how each type of filter works can help you understand why maintenance is important and what you need to do in order to maintain the filtering system.


Sand Filter

A sand filter is generally made of either fiberglass, concrete, or metal. It contains a special type of sand so that as the dirty water comes from the pool, gravity pulls the water down to the sand. The sand particles capture all the dirt and debris. The filtered water flows to the bottom of the tank and through the outlet pipe.

Maintenance for a sand filter requires you to watch the pressure inside the tank. Whenever the sand pressure goes 5 to 8 pounds above normal, the system should be backwashed. The frequency of backwashing varies, depending on how frequently the pool is used, which is why the pressure should be checked often until you have a good idea of how often to backwash the system. The sand should also be replaced every 3 to 5 years.

Cartridge Filter

Cartridge filters use a very fine filter to catch impurities. These are easy to maintain because the filter simply needs to be taken out periodically and washed. They should be replaced every 3 to 5 years.

Diatomaceous Earth Filter

Diatomaceous earth is used to filter out impurities. The backwashing requirements are the same as those for a sand filter. Cleaning and addition of new diatomaceous earth is usually needed once or twice a year.
