I am experiencing poor water pressure at all water outlets when connected to city water. When pumping tank water the pressure is fine. I have a blue filter and a pressure reducer in the hose line and have plenty of pressure at the hose end but when hooked up I measure the pressure in the galley in quarts per minute, not gallons. Question: Does the inlet fitting incorporate a pressure reducer? I can see some sort of gizmo in the inlet fitting but I can't tell what it is. This is in a 2019 LGMax.
