Need help finding filter cartridges
Our pool was built by Shasta about 6 years ago. The filter is Hayward and is called "700 square ft. Mega Cartridge Filter Model C7020STA" The parts diagram says the cartriges (quantity of 8) are part number CX590RC. We can't find these parts anywhere. Can somebody help us out with this by giving me either (a) a source that carries them or (b) the equivalent part number from one of the major filter cartridge companies?
Thanks very much!!
