Buying a Home on Well Water

Well Casing Replcement

Do you know what you can expect with a new home on a well? Buying or owning a home on well water does not need to be stressful. There are many benefits in having a home on a well! In this article we will discuss the most common water quality issues, the solutions and maintenance. Our well water treatment is personalized for your families water wants and needs.

Following an installation we will walk through with the customer what systems they have, how the systems work, how to maintain the equipment, provide yearly maintenance and warranty to ensure a long lifetime of the new water treatment equipment and prevent future issues.

Common Water Quality Issues

There are numerous water quality issues. National Water Service provides many solution’s to these problems. But the three most common issues are hard water, acidic water and water pressure.

Water Pressure

Water pressure issues are very common. It ranges from variable pressure speeds, no or low water pressure, no control over pressure or having a low yielding wells. We offer a constant pressure system as well as clean water storage tanks, pressure booster pumps, different size pressure tanks and other pressure control systems. If you are facing low pressure or no water call right away! We have a 7 day a week, 365 days a year, emergency service team ready to restore water to the home. Sometimes low water pressure is initiated by something as small as a clogged sediment filter.

Hard Water

Installation of a Chemical Feeder Pump and Solution Tank for pH and corrosion control, a Water Softener and Brine Tank for hard water and a Whole House Sediment Filter.

Hard Water is the total dissolved solids found in ground water. It can cause dryness in the skin and hair, create buildup in your pipes, spots and staining on dishes, clothing and appliances. Solids in the water may also be harmful to your family and pets health. A Water Softener uses a process called ion exchange. A specific resin is added to the tank that eliminates dissolved minerals such as calcium, iron, magnesium, and manganese. A Softener uses a brine or salt tank to clean the resin. We offer several water softener systems that ranges in price, size and function. In a home with low pH, a water softener is often paired with an acid neutralizer to raise the pH from an acidic level to neutral.

Acidic Water

Acidic Water causes corrosion, staining, leeching, spots, and may shorten the lifespan of your appliances and pipes. Acidic water leaches lead out of your pipes and appliances and enters your water supply. Lead in water is very harmful to your health, especially among young children and pregnant women. Acid Neutralizer and Chemical Feeder are Water Treatment systems that will raise your pH, eliminating your acidic water and prevent corrosion and lead leaching!


Yearly maintenance will extend the lifespan of water equipment. We also offer a lifetime warranty if the customer services with our company annually. Each service appointment our technicians checks to see if the equipment is working properly, fix or replace anything if needed, such as adding more media to a tank, replacing any sediment or Reverse Osmosis filters, UV bulbs, o-rings, salt and more. We will also test the water before and after every service to ensure your water treatment is functioning properly. Customer Service is always our #1 priority!

In Conclusion

Well water provides the end user, you, the homeowner, with the freedom and flexibility of choice. While well water, for the most part, does need some type of treatment, it comes without the added city water contaminants and chemicals such as chlorine, fluoride, Trihalomethanes (THMs), nitrates and more. Most people are unaware that homes on city water may need water treatment to remove these harmful contaminants. City water quality guidelines vary county by county. EWG provides city water contamination information based on your zip code. You may be surprised at what is in your city water. Like city water, well water may vary in quality and water volume but unlike local water systems, it is direct ground water, which does not go through chemical filtering before consumption. The natural state of the well water, great taste, environmental friendliness, and purity are benefits of well water. Well Water also provides the home owner with the freedom to install water treatment and purification systems specific to their wants and needs.

The Harmful Health Effects of Iron in Drinking Water & How to Remove Them

Water Testing
Water Test Kit

Clear looking water does not mean it does not contain unhealthy contaminants! National Water Service always tests for Iron (Ferric and Ferrous) at every service and free water quality testing appointments. You may be surprised with how much iron is in your well water and how it may affect you. If your water has a reddish or brown coloration and/or a metallic taste, it is a sign you have high levels of iron in your well water. High levels of Iron can cause many harmful health effects. Luckily Iron can easily be filtered from your water with proper equipment. 

You must be sure to test your water from a drinking source to get the most accurate water test result. If your well tests passes for iron, you still may fail from the tap if you have any iron pipes in your house. This happens when the water goes through pipes that are exposed to oxygen. In return the pipes begin to rust and leeches iron particles into the water.

The Health Risks 

(High levels of iron can pose health risks. Filtering your water is highly advisable)

Bacteria Growth

Water Testing bacteria

A tiny piece of iron makes a great home to grow and thrive for bacteria. Small particles of iron can host bacteria, which can be dangerous to humans depending on which bacteria is being festered. Once bacteria enters into your body, the bacteria can spread and make you sick. 

Iron In Pipes

When high levels of iron flow through pipes, it can build up and clog your pipes, toilets, sinks and lead to low water pressure. You may even encounter an accumulation of a reddish/ brown slime in your pipes and an unexpected rush of discolored water through the faucets.

Internal Organ Damage

Low levels of iron may be beneficial to your health, but high iron content leads to an overload (the human body stores iron in the organs). This can cause diabetes, hemochromatosis, stomach problems, nausea, iron poisoning and vomiting. It can also damage the liver, pancreas, heart and even organ failure.

Common symptoms of iron poisoning include:

  • Fatigue
  • Weakness
  • Joint Pain
  • Abdominal Pain

Skin Conditions

Iron exposed skin may result in acne, eczema and increase other pre-existing skin conditions. Iron clogged pores may result in acne. A high level presence of minerals such as iron or magnesium can damage skin cells that may lead to infection and wrinkles. 

If you find yourself or a loved one struggling with skin conditions, iron may be the cause. Medications may help, but ultimately you need to remove the iron from your water to really maximize the benefits of the medication and remove one cause. 

Beverages and Food

Iron in water may have a metallic taste that can be unpleasant. Iron contaminated water used to make any beverages such as tea or coffee, their taste will get affected. Also, water with high iron content will blacken fruits, vegetables and other foods cooked in it and spoil the flavor.


Iron Staining
Iron Staining in a bathtub

Iron tends to leave a reddish/orange/brown stain and residue on bathroom fixtures including bathtubs, showers, and faucets. If you wash dishes with iron contaminated water, you may find dark red stains on cutlery, utensils and plates. In addition, it also causes the color of your clothes to fade and reduces their quality.

How to Remove Iron From Your Drinking Water!

You Don’t Have to Accept the Health Risks!

Iron in tap water is a common problem in the DMV area. However, while the risk is real, you don’t have to accept it. 

The recommended or healthy level of iron in water is less than 0.3 mg/L. The best water treatment for iron removal is to install an IBSB(Iron breaker sulfur Breaker) water filter in your home. It helps to remove iron, sulfur, manganese and more from water, making it healthy enough to drink and preventing harmful health effects. 

For lower levels of iron a water softener and sediment filter may provide some iron filtration as well. After Installation, you and your family can enjoy safe, filtered water straight from the tap.

On City Water? EWG provides an online city water contaminant database.

Working with builders, installing well pumps and water treatment, is a one of the largest divisions at National Water Service.  Before discussing what water treatment the home may need, a well pump must installed.  We use both conventional and variable speed well pumps. Once the pump is in the well, the pipe and wire are trenched into the home. After testing the water, Water Treatment equipment is installed. Our water treatment specialists take care of all the water wants & needs for the builder and potential buyers.

Every water well is different,  as such, the treatment installed is specific to that homes water.  Should the water be hard, a water softener is recommended as well as Acid Neutralizers or Chemical Feeders for pH and corrosion control.  

We install and service Radon in Water Mitigation systems as well as UV lights for  bacteria. In addition, sediment filters, carbon tanks for odor, Constant water pressure systems and more.

Today we are digging a trench for a few new homes in Montgomery County, Maryland, bringing the water from the well into the new home as well as providing power to the well pump. No matter the temperature or weather outside, the depth of the well or the distance to the home, providing safe, clean, potable water is our #1 priority!  

One of the many reasons we all love doing what we do is that each day is different. Different well pump issues, different equipment to service and most importantly, different customer requests.

Radon is the second leading cause of lung cancer after smoking and the number one cause of lung cancer in non-smokers. The public tends to think of lung cancer as occurring in only smokers, but that is far from the truth. Lung cancer in non-smokers is the 6th leading cause of cancer deaths in the United States. Radon is not only present in the air, but your water as well. Radon in your water increases the levels in the air and puts you and your family at risk.

Sediment is made up of tiny grains of organic materials like silt, sand, rust or clay. Sediment and Turbidity (tinier pieces of sediment) are naturally occurring.  Sediment can increase in volume in water mains or pipes after a big rain storm.

Both city water and well/groundwater have sediment present.  An abundance of sediment will end up clogging your water treatment systems. As well as all of your valves, fixtures and irrigation as well as ruining hot water heaters and other appliances.

Sediment Filters are widely available at any major hardware store. However, they are often the wrong size or the wrong type of filter for the sediment in your water. This can result in a reduction of water pressure, ruined appliances and require frequent maintenance. With the installation of the correct sediment filter, you will be protecting your appliances, fixtures and water treatment. With little to no drop in your water pressure.

For over 40 years, National Water Service has been a Leader throughout the Mid-Atlantic Region for all things Water Treatment, Water Testing, and Well Pump related.
