Why Does Well Water Have White Residue? [Treatment Included] 

Common Causes for White Residue with Well Water

The primary reason behind white residue from well water is a high concentration of minerals like calcium and magnesium. These two also make your water hard. The white residue on your appliances, plumbing fixtures, bathtubs, and laundry is due to hard water.

Calcium and magnesium enter well water as a result of underground water movement. These minerals are present in soil and rocks. Moreover, calcium and magnesium are soluble elements in water and hence cannot be removed with a sediment filter.

Other minerals like sodium, potassium, phosphorous, and fluoride can also cause white buildup on your taps. Though it happens rarely, it is worth knowing.

Higher iron levels in well water can also leave stains on your appliances. Iron enters well water underground or through rusted plumbing pipes in your home.

How can I Identify what’s causing the White Scale on my Appliances?

A water test is the only reliable way to identify the culprits behind a white residue. A water test will also calculate the hardness level in your water so you can select the right treatment unit.

The EPA recommends annual testing for private wells so you can modify your water treatment options accordingly.

How to Treat White Scale from Well Water

White residue/limescale looks awful and can damage your appliances if not treated. There are two ways to deal with this problem. Let’s check out both.

Instant Remedy

You can use a DIY cleaning solution or a commercial cleaner to remove white residue from faucets, taps, showerheads, toilets, and appliances. These cleaners work instantly by removing the deposits but do not guarantee prevention. This is why we term them an instant remedy or short-term solutions.

Long Term Solution

The best way to deal with these stains is to install a water softener at your home. There are two types of water softeners; salt-based or salt-free (water conditioner).

Salt-Bases Water Softeners: These machines utilize a softening salt to remove calcium and magnesium from your well water. The process is known as ion exchange as it replaces calcium and magnesium with sodium or potassium. A salt-based water softener regenerates periodically and requires a discharge. Please note that some states prohibit salt-based water softeners, so check local laws before buying one.

1. AFWFIlters Whole House Water Softener System

AFWFIlters Whole House Water Softener System

AFWFilters’ water softener is best to deal with white stains and hard water problems. It has a softening capacity of 64,000 grains. You can use it with extremely hard water and stop worrying about stains anymore.

Salt-Free Water Softeners: A salt-free water softener is also known as a water conditioner. A water conditioner doesn’t remove or add anything to water; it changes how water interacts with other surfaces. A water conditioner uses magnetic force to crystallize calcium and magnesium in water, so they don’t stick to surfaces. Please note that water conditioners do not eliminate the stains; they just reduce them.

2.  Yarna Capacitive Water Conditioner System

Yarna Capacitive Water Conditioner System

Yarna’s water conditioner is an excellent alternative to salt-based water softeners. It is easy to install and doesn’t require drain or salt replacement. Moreover, it is cost-effective and eco-friendly. The only problem with these systems is that they cannot deal with extremely hard water.

Frequently Asked Questions 

1. Is it safe to drink water with calcium in it?

Yes. Your body needs calcium for bone growth and tissue development. Hence, it is 100% safe to drink water with calcium in it.

2. Is hard water bad for your health?

Hard water isn’t bad for your health as it contains calcium, magnesium, and iron. All three are required by your system for proper functioning and growth. However, these minerals can wreak havoc on your plumbing fixtures and appliances. Hence, it is important to remove them.

3. Can a RO system remove white scale from well water?

RO systems can remove calcium and magnesium, but they are designed for drinking water. You’ll need a bigger RO system to make your whole house water soft. This is possible at domestic levels but a whole house water softener is expensive. However, many community homes using private wells install large RO systems.

Final Words

White residue is caused by calcium in the water. While calcium is good for your health, it isn’t good for your home. So, making water safe for your home’s appliances and plumbing fixtures is important. Don’t worry about calcium deficiency; you can complete your calcium intake through your regular diet.
