Whole house systems are sized to avoid a pressure drop, with a full bypass so cartridge changes never take the property off water.

  • Main line sizing: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
  • Pressure drop management: Interpret readings against operating conditions and equipment specification; do not assume a recharge is the answer.

Whole house systems are sized to avoid a pressure drop, with a full bypass so cartridge changes never take the property off water.

What the reported symptom tells us

wanting filtered water at every outlet, not just the kitchen. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.
