Understanding your water

Know your water

You may have already noticed some issues with your home’s water. Things like itchy skin and water spots on dishes are obvious signs, while other contaminants hide in plain sight. At Aqua Systems, our first priority is to get to know your water and build your solution from there.

Common well water issues

Most well water is hard water, and it can contain other contaminants that make it smell bad, taste bad, and stain areas that get wet (showers, sinks, etc). The quality of your well water depends on your well. That’s why our first step is to test your water (at no cost to you) to determine what contaminants are present and what treatment options you need.

Common hard water issues

Local city water usually contains higher-than-normal levels of calcium and magnesium, also known as hard water. You might have dry, itchy skin and hair, dingy laundry, water spots on your dishes, and stains in your sink and shower. Hard water can also shorten the life of your appliances. Aqua Systems water softeners are designed to alleviate all of these issues with minimal maintenance and easy part replacement.

Test your water quality for free

Testing your water is always our first step. Our basic free water quality test only takes a few minutes and one, 8 oz. sample of the water from the cold side of the bathroom faucet in your home. You’ll get results about what’s in your water right away, and we can customize a solution together.
