Water Softeners & Filtration in Duluth, GA

Signs that bring Duluth homeowners to call

• A softener in the garage that came with the house and keeps running
• Chlorine taste in drinking water or ice
• Rust tint or grit from the hot side of the tap
• Pressure loss after a whole-house filter was installed
• Questions about the home's service line material

Heavy white scale is not on that list for a reason. On soft county water, it is unusual, and when it shows up a test is the first step.

Duluth's water

The City of Duluth's utilities page lists Gwinnett County Water Resources for water and sewer. Water comes from Lake Lanier and is treated at Gwinnett's Shoal Creek and Lanier filter plants, then disinfected with chlorine. The county's drinking-water page puts total hardness at 1.05 to 1.87 grains per gallon, averaging 1.34, which is soft. That makes a softener a poor first purchase for most Duluth homes; a carbon filter is the usual answer for taste.

The housing stock leans 1980s and 1990s, with a median build year of 1994, so many original water heaters are near or past the end of their life. Grit or rust from the hot side is usually the tank, not the water supply. Gwinnett maintains a service line inventory, and you can look up your line at GwinnettCounty.com/ServiceLines. Gwinnett DWR owns the meter and the pipe from the main to it; the private line from the meter to the house is the owner's responsibility.

Cost factors

• Removing an unneeded softener versus servicing it
• Carbon filter size: whole house or one sink
• Access to the main and a nearby drain
• Whether the water heater also needs attention
• Bypass valves so equipment can be serviced without shutting off the house

In many Duluth homes the most useful outcome of a visit is subtraction: taking out a softener that adds salt to soft water, then putting the savings toward a heater that is near the end of its life.
