What that means at home
Scale, spots and dry skin
At 129 mg/L (7.5 gpg), Orlando water is hard. That leaves white crust on faucets and shower heads, spots on glasses and that tight feeling after a shower.
TryCheck the shower head and the inside of the kettle for white scale.
A chlorine taste or smell
OUC (Orlando Utilities Commission) disinfects with chlorine, after ozone treatment. It keeps the water safe in the pipes. A whole-house carbon filter reduces the taste and smell at every tap.
TryRun a glass of cold water and smell it straight away.

Orlando water questions
Is Orlando water hard?
Yes. OUC gives an average hardness of 129 mg/L (7 grains per gallon), which the U.S. Geological Survey classes as hard. Hardness varies by address, so our free in-home test measures it at your tap.
Why doesn't Orlando tap water smell of sulfur like some Florida water?
OUC treats its water with ozone, which removes the naturally occurring hydrogen sulfide before the water leaves the plant. If you notice a rotten-egg smell only from hot water, the water heater is the more likely cause.
Do you install water treatment and purification systems in Orlando?
Yes. We install whole-house water filtration, which reduces the chlorine OUC adds after ozone treatment, water softeners for hardness (OUC's average is 129 mg/L), and reverse osmosis systems for purified drinking water at the kitchen sink. A free in-home water test shows which of these your water actually needs.
