How often should I perform water filtration system maintenance?

Water filtration maintenance should match the system type: Steve’s ProSeries point-of-use filter typically needs a new cartridge about every 750 gallons, while whole-house carbon filters and water softeners benefit from periodic checkups rather than frequent service. The most common driver is usage—busy kitchens and larger families reach capacity faster than light-use homes. In practice, family size affects filter life more than the calendar. We service many filtration and softener setups for homeowners in the Edmonds area. If you prefer predictable care and savings, our Diamond Club membership is $16.95 per month and includes annual plumbing maintenance, a 15% discount, a 3-year repair warranty, free service calls, and priority scheduling.

Schedule service if you notice any of the following:

• Slower flow at the filtered faucet or whole-home taps
• Taste or odor returning after improvement
• New spotting or scale on fixtures suggesting the softener needs attention
• A change-filter indicator on your unit, if equipped

Set a simple reminder to log usage and water taste each month, and book a quick checkup at the first sign of change.
