Largo's Local Water Quality Experts
Largo is the third-largest city in Pinellas County, and like most of the peninsula, its water comes from Tampa Bay Water's regional supply. With hardness levels of 10–16 GPG and chloramine disinfection, Largo residents regularly deal with scale, chemical taste, and dry skin. The H2O Heroes serve all of Largo and surrounding Pinellas County neighborhoods with professional water treatment solutions.
What's in Largo's Water?
Water source: Tampa Bay Water regional supply (Hillsborough River, Alafia River, Floridan Aquifer blend). Treated by City of Largo Utilities / Pinellas County Utilities / Tampa Bay Water. Hardness: 10–16 GPG (hard to very hard).
Hard Water Buildup
Largo water averages 10–16 GPG hardness, leaving scale deposits on faucets, showerheads, and inside water heaters and dishwashers.
Chloramine Taste & Odor
Tampa Bay Water uses chloramines for disinfection. Many Largo residents notice a chemical or medicinal taste that standard filters can't remove.
PFAS Contamination
PFAS 'forever chemicals' have been detected in regional water sources. Reverse osmosis is the gold standard for PFAS removal.
Iron & Discoloration
Some Largo neighborhoods experience occasional brown or yellow water from iron in aging distribution pipes. Whole-house filtration resolves this.
