Most municipal water systems other than the municipalities being served by Milwaukee water are around 22 grains hard. If you do not know your hardness, fill in 22. If you have a functioning softener that does not need replacement at this time, put in 0.

All municipal water systems are low enough in iron content to answer zero. If you have your own well but do not know the exact iron number, use the following hints. "I really don't see any discoloration or staining for at least a week" results in an answer of zero (0). "If I don't clean my toilets every three days they start turning brown or orange" results in an answer of three (3). "I can't do laundry without ruining white clothes" then answer five (5). "When my current softener was working better I had no iron problems" then answer zero (0).
