Replace when pressure rises quickly after cleaning, or when the pleats are torn, matted or permanently discoloured.\u003c\/p\u003e\u003ch3\u003eHow do I know what size filter cartridge I need?\u003c\/h3\u003e\u003cp\u003eFilter cartridges are specified by square footage and physical dimensions. Measure the length, outside diameter and end cap type of your old cartridge, or match the part number printed on its end cap.\u003c\/p\u003e\u003ch3\u003eWhat is the difference between cartridge, sand and D.E. filters?\u003c\/h3\u003e\u003cp\u003eCartridge filters trap particles in pleated media and need no backwashing. Sand filters are lowest maintenance but filter to a coarser level. D.E. filters give the finest filtration but require recharging with powder after each backwash.\u003c\/p\u003e\u003ch3\u003eWhen should I backwash or clean the filter?\u003c\/h3\u003e\u003cp\u003eClean when the pressure gauge reads 8 to 10 PSI above the clean starting pressure. Cleaning too often on a cartridge shortens its life; waiting too long strains the pump.\u003c\/p\u003e\u003ch3\u003eHow do I confirm this part fits my equipment?\u003c\/h3\u003e\u003cp\u003eCheck the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.\u003c\/p\u003e\u003ch3\u003eHow quickly does this ship?\u003c\/h3\u003e\u003cp\u003eIn-stock items ship from our US warehouse on business days.
