How to choose between them
Rinnai's flushing guide calls for 4 gallons of undiluted white vinegar circulated through the heater, up to about 45 minutes, at least once a year; its SENSEI bulletin specifies at least an hour at 3 to 4 GPM.
Check the hose connections against your heater's service valves before ordering.
