Located in northwestern Montgomery County, Hatfield is a welcoming suburban community with a mix of established neighborhoods and new development. While most residents receive public water through the North Penn Water Authority (NPWA), a significant number also rely on private wells—both of which come with water quality challenges worth addressing.
One of the most common issues for Hatfield homeowners is hard water, with public supply levels typically measuring between 7 and 10 grains per gallon (GPG). That’s considered “hard” to “very hard” water, and it can lead to scale buildup in pipes, cloudy dishes, dry skin, and premature wear on water-using appliances. Even if the water is safe to drink, the long-term effects of hardness on your plumbing system and budget can’t be ignored.
Adding to the concern, the region has seen rising awareness around PFAS (so-called “forever chemicals”)—prompting the NPWA to implement system-wide hydrant flushing and inspection protocols to protect water quality.¹ While these efforts are important, they don’t address in-home plumbing, old pipes, or appliance protection. That’s where we come in.
