How to Measure the Filter?
If you do not know the replacement part number, measure the filter as the following steps:
a. Measure the outside diameter of the cartridge in inches (+/- 1/16)
b. Measure the overall length of the cartridge in inches (+/- 1/16), including the end caps. Do not include any handles, strings, etc.
c. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16 inch). If the end cap is closed make note of its identifying features (i.e. “Handle”, “Cone”, etc.).
When Should You Replace Your Cartridge?
High Water Pressure:
When the running pressure of your pool filtration system starts to climb and doesn't come down after a deep cleaning of your cartridge, that can be a sign that the cartridge needs to be replaced.
Cracked End Caps:
If the end cap on either end of your cartridge has turned brittle and cracked or chipped, that cartridge should be replaced immediately to keep pieces from breaking off and damaging your system.
Torn Pleats:
The pleats do the filtering. If the fabric is torn or has a fuzzy appearance, the effectiveness of your cartridge has been compromised, and it should be replaced.
Crushed Cartridge:
When the inner structure of your cartridge has been compromised, your filter will look a bit like a crushed can. If this happens, it's time to replace your cartridge.
Never Skimp on Quality
The end caps of the filter cartridge are sturdy, and not easy to melt or crack.
Extra Pleats
More filter area for maximum filtration efficiency, providing a sparkling clean pool.
Strong Support Structure
Molded strong core provides maximum hydraulic efficiency and overall structural stability.
Easy to Install
Plug and play. Just unscrewed the cap and replace the cartridge.
