My richmond encore tankless model no. rmtgh95dvn has low water pressure coming through it. I checked the inlet filter and it is clean What else can it be?
Water Heaters - Rheem - Richmond Encore Tankless Nat Gas Outdoor Direct Vent 6.4 GPM
Old plumbing, and clogs can gather at elbows. Plumbing repairs, faulty check valves etc can cause clogs. Pressure gauge on water line can reveal if pressure drop is before or after the tankless unit.
