Frequently Asked Questions
Is the 179135 a genuine Pentair part?
Yes. The 179135 is a Pentair part supplied under that manufacturer part number. It is not a generic substitute.
How often should filter cartridges be replaced?
Most cartridges last two to five years depending on bather load, water chemistry and how often they are cleaned. Replace when pressure rises quickly after cleaning, or when the pleats are torn, matted or permanently discoloured.
How do I know what size filter cartridge I need?
Filter 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.
What is the difference between cartridge, sand and D.E. filters?
Cartridge 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.
When should I backwash or clean the filter?
Clean 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.
How do I confirm this part fits my equipment?
Check 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.
How quickly does this ship?
In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.
Can I return it if I ordered the wrong part?
Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.
Is this covered by a warranty?
Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
