Pool Filter Cleaning
At Dunman Pool and Spa, we can provide you with professional and fast pool filter cleaning. Think of how many times you and your family enjoy a day together in the crisp, clean, sparkling waters of your swimming pool. Now what would happen if the pool suddenly becomes murky or dirty over night - even though you just recently skimmed the top of the water to make sure there were no bugs, seeds, or leaves? This problem could indicate that there is something wrong with your filter, or it needs to be cleaned by a specialist. There are a variety of filters on the market, so the type you have will depend on how we go about cleaning and maintaining it.

Cartridge Pool Filters
Cartridge pool filters are one of the most common styles installed today. They can easily be cleaned, and the proper way to do so involves rinsing off loose dirt, soaking it in a special cleaner, rinsing it again, and then reinstalling it for use on the swimming pool. We will carefully remove the filter and gently brush and rinse off loose dirt and debris. We do not use any kind of spray nozzle for this kind of work since it could spray the water too hard and drive dirt further down into the cartridge. Soaking the cartridge in a specialized claner with alkaline will help to get rid of the trapped dirt from body oils and lotions that you may use when in the water. Rinsing the filter off will remove the dirt that came out while it was in the cleanser. After the process is over, we will be sure to install it properly again and test it so we can see that it's working like it should.
Sand Pool Filters
When it comes to cleaning sand pool filters, we know what to do. These sytems are designed to make use of sand that trap particles that are in the 20-100 micron range. As the sand filter collects dirt, it becomes more and more efficient - trapping more and more dirt. When the pressure gauge hits 8-10 pounds, you will know that it's time to clean and backwash the system out so that it can start the process over again. These are typically very low maintenance filters, and depending on the size of the unit, you may only need to have it cleaned a couple times a year. Most manufacturer manuals will say that the sand in the filter needs to be changed every 7 years. However, with proper maintenance and cleaning, your system's sand may be able to last for 10 years.
Diatomaceous Earth Pool Filters
Diatomaceous earth is a finely crumbled rock powder that is used to help in pool filters. To backwash or clean the filter, we will turn off the pool pump and turn the control setting to backwash. The water should be running much more clearly, and if it is, we will turn the setting to rinse. We will need to monitor the process to be sure that the systems are all working like they should. You will know that you need to schedule an appointment for cleaning when the pressure gauge on your system reaches 7 to 9 psi above the cleaning reading. We will also need to recoat the filter during your cleaning.
