- #1 Measure the outside diameter of the cartridge in inches (+ or - 1/16")
- #2 Measure the overall length of the cartridge in inches (+ or - 1/16"), including the end caps. You don't need to include any handles or strings. A more accurate measurement can be obtained by measuring through the center hole of the pool cartridge when possible
- #3 Make a note of the (OEM) original manufacturer model number of the replacement cartridge
- #4 Take note whether or not there is a center core (PVC pipe in the center) and also count the number of pleats (+ or - 2)
- #1 Count the number of pleats and measure the pleat depth in inches
- #2 Measure the length of the cartridge in inches excluding the end caps
- #3 Multiply the number of pleats by 2 and multiply that number the the pleat depth. Multiply the total by the length of the cartridge (excluding the end caps) and divide that number by 144
- Example:# of pleats x 2 x pleat depth x pleat length divided by 144 = cartridge square footage
- When the pressure gauge on your filter tank reaches 8 PSI above the pressure recorded when a new cartridge is installed, or when there is a decrease in pressure coming from your return jets.
