Pool Filter Services with Blue Crystal Pool Service

A filter cleaning is not to be confused with a filter backwash. Our filter cleanings include:
  • A full disassemble on all the grids and filter internals.
  • Cleaning the internals and the inside of the tank.
  • Using an acid solution as needed to remove any calcium buildup on the grids.
  • Lubricating the backwash valve if it is a push pull or slide.
  • Resealing the tank.
  • Re-charging the filter with DE (if needed).
  • Testing for proper filtration.

There are three major types of swimming pool filters. These are Sand, Diatomaceous Earth (DE) and Cartridge filters. Each has a few advantages and disadvantages.

Sand Filters

Sand filters are the oldest style of pool filtration. While still the filter of choice for many commercial applications, they have lost a lot of popularity for residential uses. The filter has dirty water go in the top and the sand particles will trap debris and dust letting clean (or cleaner) water out the bottom that will return to the pool. Sand filters can be run continuously (unlike DE filters) and are fairly simple to maintain. They can be backwashed and do not normally need to be disassembled and cleaned like a DE or Cartridge filter.

Over time the sand particles in a Sand filter will “round” out like stones in a stream and eventually become less adept at grabbing the particles in the water going through them. When this happens you can usually see dust and cloudy water coming back into the pool. The remedy is to change the sand out in the filter.

The big disadvantage with sand filters is they do not filter nearly as fine as a DE or Cartridge filters. A sand filter will get down to 20-30microns. To a trained eye there can still be a small amount of cloudiness in the water coming back into the pool. This means the water will not “sparkle” as much and some people feel it is always slightly cloudy. It is also much more difficult to clear up a pool that has turned green with algae when using a sand filter. One trick is to add some DE to help it filter a little finer. It is also helpful to utilize a flocculent product or clarifier to cause the small particles to congeal into a larger size where the sand can grab them.

Diatomaceous Earth Filters

Also called “DE” filters for short, these filters offer the finest filtration available. They are usually comprised of plastic grids that look like waffles that are coated in DE or “earth” from ground up crustaceans. DE filters will refine the water down to 2-4 microns. Because of this ultrafine filtration DE filters tend to get stopped up if they run too long continuously. They need to have an hour or two off per 24 hour period for the DE to fall down in the tank and then later recoat the grids upon being restarted.

DE filters should be backwashed on a regular basis. Manufacturers often say they should be backwashed when the pressure is 10psi higher then what it is clean. If you are a Blue Crystal Pool Service customer on regular maintenance we will backwash your DE filter once a month or sooner if the pressure rises 5psi higher than what it is clean.

Many manufacturers recommend DE filters be completely disassembled and cleaned once every 6 months. While there are costs associated to this if you hire a swimming pool company to do it, these costs are usually completely offset by the savings in electricity and in reduction in wear on the filter pump.

Since DE filtration is so fine, another benefit is the equipment can be run less with the same filtration results saving on electricity.

Cartridge Filters

Cartridge filters have either 1 or multiple cartridges inside them. The cartridges are usually round and made of cloth with a number of folds. They appear like an air filter in an automobile. Cartridge filters are not able to be backwashed and as a result must be disassembled and cleaned like DE filters on a regular basis. This is the only way to get the dirt out of them. While many manufacturers recommend a full disassemble and cleaning every 6 months, we have found in circumstances where a lot of dirt or debris gets in a pool that more frequent cleanings can be warranted.

Cartridge filters are able to withstand a little higher pressure than DE filters. So they can be paired with a higher horsepower pump on install. Due to the cloth fabric they are also the best at trapping and filtering out oils in the water from tanning lotions or bather usage.

What Types of Pool Filters Need to be Cleaned?

Filter cleanings are necessary for nearly all residential swimming pools in Katy, TX. The reason for this is approximately 98% of residential swimming pools in Houston areas are either DE (diatomaceous earth), cartridge, or some combination of the two types called a hybrid. The remaining 1-2% are sand filters which do not disassemble and clean up without a sand change. Commercial swimming pools in comparison are nearly all outfitted with sand filters for several reasons.

Don't void your pool filter warranty!

Filter manufacturers and swimming pool builders require regular filter cleanings to ensure their warranties are not voided. They usually recommend filter cleanings them every 3-6 months depending on which type of filter and the manufacturer.

A swimming pool filter warranty will also usually be voided by a home warranty company without proof of regular filter cleanings.

If you have home warranty coverage on your pool equipment they will usually refuse coverage on your filter repairs if you cannot demonstrate it has been well maintained with regular filter cleanings. Unfortunately many swimming pool owners find out about this after it is too late. Did you know filter cleanings pay for themselves?

Did you know filter cleanings pay for themselves?

The electricity savings alone will often cover the cost. To verify this just put a voltmeter on the filter pump motor and measure the amount of amps it is drawing when running before and after your filter cleaning. NOTE: If you are not familiar with electricity or qualified to do this please hire a professional.

A dirty filter that has been cleaned will often drop the average pressure on the tank by 5-10psi. This increased flow through the filter means the filter pump will draw less amps or power. Since your filter pump motor is one of the biggest consumers of power in your home this savings in power will directly affect your electric bill. Why give this money to the electric company when you could have a healthier pool instead?

With a clean and maintained pool filter you will:
  • Lower your electrical bill - this alone could pay for a swimming pool filter cleaning.
  • Get healthier pool water - 10-20lbs of dirt and gunk will no longer be in your swimming pools circulatory system. Your pool water will no longer be pumped through this gunk. Also you will be at less risk of algae outbreaks.
  • Prolong your pool filter's life - less stress on the internals means less repairs.
  • Prolong the life of your filter pump motor - less resistance from the filter means it can do its job of moving your pool water more easily.
