That pool taste in your coffee and ice is chlorine, the disinfectant this system uses. Everything here is published data for this system. The recommendation follows from it.

Water system boundaries interlock around here, so we confirm yours by address before we quote anything.

What we'd install

Based on the report, whole-home carbon for the chlorine at every tap. A pH neutralizer goes in ahead of it to bring the water back to balance. Reverse osmosis at the kitchen sink is optional, for drinking water and coffee. The quote lists it as its own line so you can take it or leave it.

What this does for your home
  • Easier on the rubber seals, gaskets, and hoses inside your appliances
  • No chlorine taste or smell in your coffee, tea, and ice
  • Balanced water that stops eating at your copper plumbing
  • Bottled-quality drinking water on tap for pennies a gallon

Easier on the parts that wear out

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.

What this means at your house

Your water arrives with chlorine in it, at 2.3 parts per million. That is the disinfectant the Northridge Estates system uses, and it is the taste people notice 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. This water arrives in that same range. Carbon takes it out at every tap in the house.

This is soft water. Hardness tests at 8.9 milligrams per liter, about 0.5 grains, and for a family using around 300 gallons a day that puts roughly 8 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 Goodbee Regional Well. The pH here runs acidic, at 5.65. Acidic water works on copper plumbing, which is where blue-green stains around drains come from. A neutralizer brings the pH back to balance ahead of everything else.

How the report becomes the recommendation
