General Water Questions

Can I do this myself instead of paying for it?

Yes. We can assist you by providing the equipment so you can install it yourself.

Does the state regulate plumbers to be certified?

Yes, by the IDPH, Illinois Department of Health.

Are you the cheapest option?

We sell all makes and models.

If there’s bad stuff in my water, why hasn’t the city done something about it?

They can’t make the water perfect for drinking when 99% is used for industry and only 1% for human consumption. Water goes through a water TREATMENT plant, not a water FILTRATION plant.

Isn’t well water regulated somehow?

No. If you have well water, it’s 100% YOUR responsibility to test and maintain the quality of your home’s water. Although the U.S. Environmental Protection Agency has rules that protect public drinking water, it doesn’t govern well water. In fact, government agencies recommend you frequently test your well water for possible contaminants

How do I find out what’s in my family’s drinking water?

The only way to be entirely sure about what’s lurking in your family’s drinking water is to have professional water testing done. You can schedule water testing with Angel Water at the best time for you.

How do I know what type of water quality equipment my home needs?

The type of water quality equipment your home needs depends on the contaminants found. We recommend getting water testing done first. Then, one of our professionals can discuss the best water quality equipment for your home’s needs.

What’s the difference between water treatment and filtration?

Questions about water treatment versus filtration are common. After all, they sound like the same thing, right? But they’re two very different things.

Water treatment is what the city does to its drinking water. The purpose is to make it safe by adding treatment chemicals like chlorine or chloramine. During the treatment, trace chemicals and tiny organisms in your water are eradicated. The problem? Not everything harmful will be removed in the process, and the chemicals used aren’t safe themselves. That’s why people need water filtration systems in their homes.

Water filters remove a more comprehensive range of chemicals, organisms, sediment and more. Precisely what and how much will depend on the exact filter you use. A high-quality filter will remove everything unsavory from your water, protect your family’s health, extend the life of household appliances and make water taste better. The best part is that this is done without harmful chemicals like chlorine or chloramine and instead use filters.

What contaminants could be in my drinking water?

This one may have the most surprising answer among water questions because most people don’t realize the potential severity of water quality issues. Contaminants can be physical, chemical, biological or radiological. Specific contaminants include radium 224/226, barium, bleach, nitrogen, rock sediment, bacteria, parasites and many more.

What health problems might arise from contaminated drinking water?

The most common issues you hear about from contaminated drinking water are cholera, dysentery, and typhoid. However, contaminated water can also cause polio, cancer, Crohn’s disease, kidney failure, hepatitis, autoimmune disease and much more.

Water Softeners

What is water softening?

Water softening is simply a mechanical method of removing rock from water.

Can I take my water softener with me when I move?

Yes. With modern water softeners, it is possible to take them from one installation location to another. Some modern systems even include quick-fit connections similar to those used for laundry machines. If this is particularly important to you, ask your Angel Water Expert for insight!

How much does a water softener cost?

Water softeners range in price and payment options. To determine the price, we need to understand your water quality and how many gallons of water are used daily.

How often does a water softener be maintained?

You should have your water softener professionally maintained at least once a year. Annual maintenance will help your equipment last the longest.

Water Filtration

What is a whole house water filtration system?

A filter that’s designed to improve the water quality throughout the entire home. Usually, these systems improve the odor and quality of the water.

Are there different types of whole house filtration systems?

Yes. They are all based on the issues you want to solve in your water.

What does a whole house water filter get rid of?

Depending on the configuration you decide on, a filtration system can remove a wide range of contaminants that may threaten your family’s health. Some of the more common contaminants people want to filter are Radon, Arsenic, Chlorine, Lead, Mercury, and VOCs.

Coupled with a Reverse Osmosis System, you can be sure you have the cleanest water possible!

What should I do if I want a water filtration system but live in a rental?

If you rent and are restricted on what you can do with the home, we recommend choosing our Countertop Reverse Osmosis (RO) Filter. Although it won’t tackle filtering the water you shower in or use in your appliances, it creates pure, clean water for your family to drink – and lets you simultaneously ditch the water bottle habit!


What is hard water?

Hard water is simply water with dissolved rock that you can’t see. This rock makes faucets, showers, tile etc, crusted with white rock.

How often should one add salt to a softener?

It ranges based on water quality and water usage. On average, it’s every 6-12 weeks with modern, high-efficiency water softeners.

How long does a water softener last?

This depends on the quality of the system you purchased, the quality of your water and how much water you use. We usually see the cheaper systems last 1-2 years and the higher quality systems last 10-15 years.

What happens if I don’t regularly maintain my water quality equipment?

Among water questions, this is perhaps the most important. Without regular upkeep, maintenance and oversight, your water quality equipment may break. But breakage isn’t always obvious. Sometimes, forgoing maintenance can mean your system stops working without you knowing, and the water you thought was safe is now contaminated again.
