Water system boundaries interlock around here, so we confirm yours by address before we quote anything.
Based on the report, whole-home catalytic carbon for the chloramine at every tap. If better drinking water matters to you, reverse osmosis at the kitchen sink does that. If not, skip it; the whole-home catalytic carbon does its job either way.
Sediment settles in your water heater and lowers its efficiency, and chlorine and chloramine embrittle the rubber seals, gaskets, and hoses inside your appliances over time. Filtering the whole house is gentler on all of it.
U.S. Dept. of Energy Energy Saver; ASTM D6284.Your water arrives with chloramine in it, at 2.0 parts per million. That is the disinfectant the Cross Gates Special District uses, and it is what people taste in coffee, in ice, and in the first glass of the day. For context, swimming pools are kept between 1 and 3 parts per million of chlorine, and this water's disinfectant level lands in that same range. Chloramine does not gas off in a pitcher the way chlorine does, so catalytic carbon is the piece that takes it out, at every tap in the house.
This is soft water. Hardness tests at 5 milligrams per liter, about 0.3 grains, and for a family using around 300 gallons a day that puts roughly 5 pounds of dissolved rock through the house in a year. Genuinely hard water runs well past a hundred pounds a year, and that difference is why a softener is not in the package for this neighborhood.
The water here is groundwater, pumped from Cross Gates and Meadow Lake wells.
Each finding decides a piece of the package, including the pieces we leave out.
| The report shows | At your house | The answer | Why that one |
|---|---|---|---|
| Chloramine at 2.0 ppm | The taste and smell in coffee, ice, and the first glass of the day | Whole-home catalytic carbon | Chloramine holds together inside plain carbon. Catalytic carbon is processed to break it apart. |
| Hardness at 0.3 grains, soft | No scale problem to fix | No softener | The resin would have nothing to grab, so it stays out of the quote. |
