What it has going for it
Part 804000074. Condensing units make acidic water. The media raises its pH before it hits a cast-iron drain or the septic tank, and it needs a refill now and then.
For Rinnai. Parts like this are model-specific. Match the part number in your manual before you order.
Only condensing heaters make acidic condensate. The listing names Rinnai heaters and part 804000074.
A non-condensing unit has no use for it. Check your heater's manual for "condensing" and the drain it asks for.
