What We Do in Mullins
From free testing to whole-home treatment, ClearFlow handles every step of your water quality journey right here in Mullins.
Free In-Home Water Testing
Our trained specialists come directly to your Mullins home and test your water on-site for common concerns — including hardness, chlorine, iron, and more. You receive a full written report with every result explained clearly. There is no cost and absolutely no obligation to purchase anything.
Whole-House Filtration Systems
If your test identifies issues, we recommend a whole-house filtration system sized for your home and water profile. These systems treat water before it reaches your faucets, showers, and appliances. Treatment capabilities and performance are defined by the manufacturer's published specifications and vary with water conditions.
Reverse Osmosis Drinking Water
For families who want an added layer of protection for their drinking water, we install under-sink reverse osmosis systems designed to reduce a wide range of contaminants including PFAS, lead, arsenic, nitrates, and TDS. Performance is based on manufacturer specifications and varies with water conditions.
Common Water Problems in Mullins
Water quality varies by location, source, and infrastructure. Here are the most frequently encountered issues our Mullins customers report before testing.
Hard Water Scale
Mineral buildup on faucets, inside water heaters, and on dishes is one of the most common complaints homeowners report to us. Scale accumulation is a widely documented maintenance concern for plumbing and appliances.
Chlorine Taste & Odor
Municipal water treatment uses chlorine or chloramine to disinfect water. The residual taste and smell at the tap is a sign your water needs a whole-house carbon filter.
Iron Staining
Orange or rust-colored stains in sinks, showers, and toilets are a telltale sign of elevated iron — common in both well water and older municipal distribution systems.
PFAS 'Forever Chemicals'
PFAS have been detected in some water sources across SC and NC, and the EPA has established federal drinking water standards for certain PFAS compounds. Testing is the only way to know whether they are present in your water.
Lead from Old Pipes
Homes built before 1986 may have lead service lines or lead solder. Lead is undetectable by taste or smell; it requires a certified test to confirm.
Rotten Egg Smell
Hydrogen sulfide gas from well water or waterlogged plumbing creates a sulfur odor that makes water unpleasant to drink, cook, and bathe in — a problem we treat routinely.
