Clogged Filter
Home water filter clogging is more common in the spring and fall, when algae blooms occur. The most prevalent form of algae in our water system (diatoms) can very quickly clog filters. You may notice that you have to change the filters more often and that they appear to be covered with clay or plaster. There is currently no known health risk due to the algae.
To alleviate the filter clogging problem, an inexpensive pre-filter can be installed. The pre-filter can then be removed, cleaned with a brush or just replaced with a new one. This technique will protect the more expensive cartridge filters and prolong their life.
