Frequently Asked Questions
How often should cartridge filters be cleaned?
Most cartridge filters should be cleaned when pressure increases
approximately 8-10 PSI above the clean starting pressure. Cleaning
frequency depends on pool usage and debris load.
Can cartridge filters be used with saltwater pools?
Yes. These cartridge filters are compatible with both traditional
chlorine and saltwater pool systems when properly maintained.
Do cartridge filters require backwashing?
No. Cartridge filters do not require backwashing. The filter cartridges
are removed and cleaned with a garden hose, helping reduce water
waste.
How do I find the correct replacement cartridge?
Replacement cartridge compatibility is based on the filter model
and square footage. Always verify the replacement cartridge part
number listed for your filter model.
Are these filters compatible with variable speed pumps?
Yes. Most inground cartridge filters are compatible with standard
single speed and variable speed inground pool pumps when plumbing
and flow rates are properly matched.
Who handles warranty claims?
Doheny’s handles warranty support for Doheny-branded filters, while
manufacturer-branded products such as Hayward and Pentair may require
initial manufacturer contact for warranty assistance.
