| HOW DO I KNOW IF IT IS TIME TO REPLACE
MY FILTER CARTRIDGE? |
| Since Filter Cartridges have no moving
parts or electrical switches to fail, Filters Cartridges do not have a
defined end-of-life. Instead the cartridge media will gradually plug up
over time. In a typical spa, the culprit that plugs the cartridge
media is perspiration and body oils combined with soaps, chemicals and
very fine particulate. In a swimming pool, the loading is primarily
debris along with suntan lotions and organic matter such as algae.
Assuming the Filter is properly maintained and correctly sized to the
pump, determining when the Filter Cartridge is in need of replacement
depends primarily upon three factors:
- Shorter cycle time between cleanings.
- Low water flow rate and high differential pressure.
- Catastrophic failure such as a tear in the media or center core
collapse.
All three are dependent upon proper swimming pool or spa water
chemistry and following a routine maintenance schedule. Filter elements
are plastic and should be handled and maintained accordingly. |
