Tap water in Pebble Creek has about 139 mg/L of hardness, which is 8.1 grains per gallon. On the USGS scale that counts as hard. The number comes from City of Tampa Water Department, dated September 2025.
At 139 mg/L, Pebble Creek is 19 mg/L above the typical Florida figure of 120. Of the 10 nearest cities we track, 7 have softer water and 3 have harder. The range nearby runs from 111 mg/L in University to 159 in Plant City.
What 139 mg/L means at home
Expect white crust on faucets and showerheads, plus spots on dishes that come out of the dishwasher.
Kettles collect scale quickly. Water heaters build up sediment at the bottom of the tank, which makes them work harder over time.
Soap and detergent need a little more to lather, and soap scum shows up in the tub.
Hardness is not a health problem, and EPA sets no limit for it. It is a matter of scale and soap.
What to do about it
At 139 mg/L most of the trouble is scale, and only a few things deal with it.
Ion-exchange water softener
The standard whole-house fix. It swaps calcium and magnesium for sodium or potassium and needs salt plus a drain. Size it with the calculator below.
Salt-free conditioner
No salt and no drain line. It changes how minerals form scale instead of removing them, so water still tests hard.
Reverse osmosis or carbon filter
Under-sink reverse osmosis removes minerals from drinking water only. Plain carbon filters improve taste but do not soften.
3 people × 75 gallons a day × 8.1 gpg = 1,829 grains a day. A 24,000-grain unit regenerates about every 13 days.
