You’ve just had a pool installed or moved into a house with a beautiful fiberglass inground pool out back. Great! Now you need to build good pool maintenance habits which may take some time, especially if this is your first pool. Any pool company will tell you one of the most important elements of any swimming pool maintenance program is taking care of the filtration system. The pool filter is the heart and soul of the pool in that, if it fails, there will be no swimming until it is back up and running. Below we’ll go into the important role the filtration system plays and then outline the most popular kinds of pool filters.
What the Pool Company Should Tell You about Pool Filters
The pool company that installed your pool should have taken the time to discuss the importance of the filtration system with you. If they didn’t, or you have moved into a house with an existing pool, or you just need a refresher course read on.
What is the filter and why is it so important?
The filter removes particles and pieces of debris large and small from the pool water. As such it is vital to keeping the water clean and swimmable. It is also vital that the filter be the appropriate size and be in good working order. If it’s not you may experience cloudy water that is unsafe to swim in.
There are 3 major types of pool filtration systems a pool company will install in Toronto. They are:
- Cartridge Filters: Cartridge filters utilize a replaceable filter that captures tiny impurities that may be circulating in your pool. They’ll stay trapped in the cartridge until the filter is either cleaned or replaced. Cartridge filters are very effective and easy to maintain. In most cases maintenance will entail simply turning off the system, removing the filter and rinsing it with a garden hose. Cartridge filters typically operate at lower pressure than other filters which relieves stress on the entire system and makes for a nice, smooth circulation of water.
- Sand filter: A sand filter is just that; a container of clean, fine-grain sand that captures impurities and removes them from circulation. Water enters the filter at the top and is pulled by gravity down through the fine sand. The sand sifts dirt and debris from the water and clean water is returned to the pool. You’ll be able to tell it’s time to clean the filter by checking the pressure gauges on the intake and outflow pipes. If the intake pressure is the greater of the two the sand is becoming clogged and should be backwashed. This type of filter should be replaced every 4 to 5 years.
- DE filters: A DE or diatomaceous earth filter utilizes the finely ground skeletons of diatoms. Diatoms are a type of single cell organism that band together into different shapes enclosed by a silica wall. It is actually the finely ground remains of this protective wall or shell that is used in the DE filter. DE is so fine and porous that many pool experts consider it the best material for filtering swimming pool water. If DE filters have a downside it’s that backwashing the DE filter is a more involved process than it is with a sand filter.
