Your water might taste a little odd. Maybe you’re cleaning your tub on a nearly daily basis to prevent staining. And the dishes come out of the dishwasher with cloudiness you can’t get off. Your clothes are getting worn out much faster than they should be. Even getting your hands and hair to feel clean feels like an uphill battle. On top of it all, your appliances aren’t lasting as many years as they should, and your water and electric bills are higher than other people you know who use the same amount as you.

You have hard water. Our team at Kay Plumbing is up front about our costs, and we never hide fees. We come fully ready for the job when we arrive, and we can answer any questions you may have about your options for water treatment systems.

Save Time on Daily Chores With a Whole Home Water Softener

Hard water isn’t inherently bad for you, but it can have negative effects on your household and home.

The mineral content of your water affects the way it tastes. Plus, it can dry out your hair and skin or worsen existing skin conditions, make it hard to keep your shower and sink clean, and even affect your water pressure if the minerals build up in your plumbing.

End The Extra Wear & Tear on Your Belongings

Calcium from hard water can build up in your appliances and pipes, shortening their life expectancy and requiring frequent repairs. It can stain dishes, clothes, sinks, and tubs.

Filter Your Drinking Water & Improve Its Taste

Your home’s drinking water might be fine for showering or brushing your teeth, but not for drinking. You don’t have to treat your entire home’s water system for pleasant-tasting water. You could try a water filtration kit that can be installed under your sink to improve your drinking water. And, a filtration system could save you money on bottled water.

Frequently Asked Questions

Why is water treatment important?

Water treatment includes filtration and softening. Water filtration systems protect your household from dangers that could be in your drinking water, like bacteria or chemicals, and they can also improve the quality of taste. Water softening systems reduce calcium and magnesium levels in your water so that it’s less abrasive to your plumbing, appliances, and other belongings, and may also improve the quality of taste.

What is the difference between water filtration and water purification?

Both types of water treatment service remove unwanted elements from water. Water filtration usually removes large particles, like bacteria, and it can improve the taste and color, as well as quality, of your water. Water purification can remove smaller particles, like chemicals or viruses. It usually uses a process called reverse osmosis, which is basically when water is pushed through a membrane that keeps unwanted particles out. Kay Plumbing offers both services, and we can help you figure out which is best for your household.

What is the difference between hard water and soft water? How do I know which one I have?

The primary difference between hard and soft water is what minerals you’ll find in them. In hard water, you’ll find higher levels of calcium and magnesium, and in soft water, you’ll find more sodium, or salt. You can tell if you have hard water because you might feel a film on your hands after you wash them, or notice your dishes are cloudy when you take them out of the dishwasher. This is because the calcium leaves a residue on clothes, dishes, and other things that use the water. You won’t notice these problems if you have soft water.

Is hard water safe?

Generally, yes. It may even be contributing to your calcium and magnesium intake. If someone in your household has a skin condition like eczema or you’re having issues with dry hair or skin, hard water can contribute to or exacerbate these issues.
