Don’t worry, plenty of people (besides you) made the inadvertent mistake of leaving the filter cartridges in the filter over the Winter, or worse yet, made the inadvertent mistake of mixing the cleaning solution a wee bit too strong in the Spring.
No worries. Simply type in you old filter cartridge’s dimensions into the very convenient ‘cartridge calculator‘ featured on InTheSwim.Com.
How Do You Test an Old Cartridge Filter?
If you wet the thing and it falls apart, or it falls apart even when dry, you have your first clue. After that, if you put the thing in after a thorough and proper cleaning and the pressure on your filter system keeps heading towards the sky, well, now you have a second clue.
Whether your pool/spa sits outside or under the protective cover of a roof, it still collects dust, debris and other nasty things which can ruin the fun of an afternoon swim or late night soak. Those same nasty items can ruin your health.
In an effort to prevent either of those tragedies, pool and spas come equipped with inline filtration systems designed to remove unwanted items from the water. Several different types of systems are commonly used:
- Sand — Often found on aboveground pools and on commercial pools. Water passes through a body of sand and as it does so, larger particles get filtered out.
- Diatomaceous Earth — Often found on inground pools of all sizes. Cloth covered fins or ‘fingers’ coated in a silt-like, white, material which looks very much like finely ground chalk filter out unwanted solids.
- Cartridge — Often found in spas and on very small aboveground pools. Porous paper sheets filter out unwanted solids.
