Frequently Asked Questions

Common problems with a whole‑house water filter include clogged cartridges or media, pressure drop, leaks at the housing or head, valve or bypass faults, and systems that are undersized for the home’s flow. The most common cause is normal buildup that saturates the filter, which restricts water and can bring back tastes or odors. On service calls around Solvang, we often find pressure loss traces back to overdue media changes or a mis-set bypass. A quick technician check is to compare pressure before and after the filter; a large difference points to the filter, not your plumbing. Work we recommend is backed by our standard 2‑year warranty, with a Lifetime upgrade option available.

Watch for these decision signals:

  • Sudden whole‑home pressure drop or sputtering after high use.
  • Return of chlorine taste or odors ahead of schedule.
  • Drips at the canister, head, or unions after a cartridge change.
  • Good pressure with filter bypassed but poor pressure when engaged. Always depressurize the line before opening any filter housing to prevent injury or water damage.
