How To Choose The Right Company
Hard water and unsafe water are not interchangeable concerns. A softener is designed to address hardness minerals, while iron, bacteria, lead, PFAS, or other contaminants may require different treatment approaches. The New Jersey Department of Environmental Protection advises homeowners to identify the water problem and review test results before selecting treatment equipment, including devices that remove hardness minerals.
- Request the actual water test results, not just a verbal recommendation.
- Ask how the system will be sized for hardness and household demand.
- Confirm whether the proposal includes plumbing, drain connections, programming, and final testing.
- Review equipment and labor warranty terms in writing.
- Ask who will handle maintenance and future repairs.
- Compare at least two written estimates for a major installation.
For private-well households, regular testing is particularly important: New Jersey reports that about 12% of residents rely on a private well for drinking water. A test-first approach helps ensure the equipment matches the conditions at the property.
