Are you interested or do you think you need water treatment for your home or place of business? Here are some of the benefits of using National Water for your water treatment needs:

Free Consultation:  Before we install any water treatment system, we send one of our experienced technicians to your home or office for a free consultation. We test your water, discuss with you our findings,  talk about what you like and don’t like about your water and what you are looking for in a water treatment system. Only after the consultation will we make recommendations as to what water treatment system best suits your wants and needs.

Safer, Cleaner Water: Undoubtedly, the top benefit of installing a water treatment/purification/filtration system is that you will have safer, cleaner water that will benefit the health of you and your family members. A  water treatment system, which National Water always customizes to each individual customers wants and needs,  can remove impurities such as sediment, chlorine, radon, bacteria and other contaminants from your water. In addition to being cleaner and safer, your water will also smell and taste better and you will no longer have to spend money on plastic water bottles that end up in our landfills.

At National Water, we don’t just address the contaminants in your water, but any other issues you may be having with your water such as pH and hardness. Addressing the issue of hard or soft water or low or high pH with a water treatment system will prevent corrosion in your pipes as well as spotting on your dishes and staining on your appliances. In addition, we offer flood prevention, storage tanks for low yielding wells, constant pressure systems and much more to allow you to be in complete control of your water.

As winter roars its ugly head, it is important to ensure your well pump and water treatment systems are working properly to get you through the freeze!

Today, we replaced a very old well pump with a new Grundfos well pump for a very happy new customer in Gaithersburg, Maryland.

She awoke this morning to No Water in her home. Our Emergency Well Pump Division was at her home as the sun was rising to diagnose the issue. Once we pulled the pump out of the well, the problem became apparent, a broken wire and a rusted out hole in the pump. A new pump and wire were installed, water has been restored to her home and this Gaithersburg, MD resident is ready for winter! 


Fixing or replacing a well water pump usually involves our pump truck or an “upsy-daisy” to pull out the pump and locate the problem. This can be done with minimal equipment and a small crew. However, sometimes, fixing or replacing a well water pump involves a lot of parts and tools and climbing into a small pit to address the issue. The customer was so happy with our preparation and work ethic that he came out to watch and thank us personally.


Back in the early 1900’s when this well was dug, it supplied water to three different properties. In 1969, the properties were combined into one and a municipal water line was connected to the pitless adaptor of the well. The well and pump were subsequently abandoned and municipal water was used for the property.

Our customer purchased the property in 2016 and asked us to remove the municipal water line and re-build the well. We installed a new pump, an in-well pressure tank and re-built a hand pump for use both in the buildings on the property as well as for irrigation.

The rebuilt well, pitless, pump, pressure tank, hand pump, well cap, casing and conduit will allow unlimited flow of water for all our customers needs for years to come.

In addition, we found an intact, late 1800’s whisky bottle about 5 feet underground next to the well.

Cold weather is hard on everything, and well pumps are no exception. Today we replaced a well pump for a new customer in Clarksville, MD. We removed her old pump and replaced it with a new Grundfos variable speed pump.

A variable speed pump also gives the home owner the option for a Constant Pressure System. Constant Pressure systems gives the consumer the ability to control the pressure of your water at all times, while ensuring you never run out, no matter how many people are using the water at once!


Etching is the erosion of the surface of glassware, tiny pits or “scratches” on the glass. Sometimes you might some effervescent coloring on your glasses in the early stages. Sometimes a milky color that will not dissolve off or it might look like it has been lightly sandblasted. Etching can happen in any dishwasher, doesn’t matter if the water used to clean the dishes is soft or hard water, although it is more commonly occurs when the water has been mechanically softened by a water softener. It can also happen to any grade of glassware. Dollar store glass or top notch glass. The cause of etching on dishes can be from too much detergent in soft water, items that are pre-rinsed multiple times, or washing dishes in water that is too hot.
Glassware damaged by etching can’t be fixed. But it can be stopped. Try changing the amount or type of detergent that is used. Also, try checking the temperature of the incoming water. Go to a faucet near the dishwasher, then turn on the hot water for around 45 seconds or till the water gets hot. Then run water in a glass and place a thermometer in the glass and check the temperature. It should be within 120-140 degrees.
For another quick fix to etching problems stop pre-rinsing dishes. Detergent needs the grim and food left on the plates to work the way it was designed to work. If there isn’t food or dirt on the dishes the detergent works away the outside layers of the glassware.
It is a challenging problem when encountered & is gradual & usually does not occur overnight. Typically when you notice the results of etching the damage has been done. It requires some experimentation to find the correct formula of detergent and water supply to solve the problem.
You can perform a simple test to see if your dishes are etched or if they are simply coated with mineral & soap build up. Put some lemon juice on a small area of the effected glassware & allow it soak for 5-10 minutes then wash it off. Allow the glass to dry. If that spot you put the lemon juice on is much cleaner than rest of the glass than it is not etched & can be restored. If the spot you put the lemon on looks unchanged then it is most likely etched.

The most common question we receive from new customers is “What water treatment systems do I have and what are their functions?”

Every well and every homeowners water wants and needs are different. One of our main objectives is to only install the equipment that our customers need to ensure that they have clean, safe potable water.
We have found that the majority of new home owners are not familiar with the equipment that makes up their water treatment system. We strive to educate all of our customers so they know exactly what type of water  treatment they have and its function.

Each new customer, be it a new installation, or someone who purchases a home with water treatment that we service, receives a picture, like the ones below, to help them identify what exactly they have treating their water!

Since the 1940’s, most Americans have been told of the health benefits of adding Fluoride to our water, our toothpastes and to “gargle and spit” while at the dentist. However, recent studies by the world’s oldest and prestigious medical journal, The Lancet, have officially classified fluoride as a Neurotoxin, the same category as arsenic, lead and mercury. The report specifically notes that neuro-developmental disabilities from fluoride including attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, are now affecting millions of children worldwide in what they call a “pandemic of developmental Neurotoxicity.” If you’ve ever noticed the warnings on toothpaste labels you probably know just how serious fluoride poisoning can be, especially for children if they swallow too much at one time.

The report in The Lancet coincides with 2013 findings by a Harvard University meta-analysis funded by the National Institutes of Health that concluded that children in areas with highly fluoridated water have “significantly lower” IQ scores that those who live in areas with low amounts of fluoride in their water supplies. In addition, Fluoride can lead to dental and skeletal fluorosis, or a hardening of your bones and joints, resulting in higher risk of fractures or breaks. Cardiovascular problems have also been linked back to fluoride, including high blood pressure, arteriosclerosis, cardiac insufficiency and even heart failure.

Due to these findings most developed nations in the world have rejected fluoridation, including 97% of western Europe. The United States, which fluoridates more than 70% of its water supplies, is an exception to this rule. According to the British Fluoridation Society, there are more people drinking artificially fluoridated water in the United States than all other countries combined. The Center for Disease Control (CDC), a main proponent of fluoride, stated that “as a result of water fluoridation, dental caries declined precipitously during the second half of the 20th century.” However, what the CDC has failed to mention is that tooth decay rates have “precipitously declined” in all western countries, irrespective of whether the country ever fluoridated its water. 

Despite these reports, most Americans consider fluoride to be an important part of our countries water purification.  All water treatment chemicals, with the exception of fluoride, are added to make drinking water safe and pleasant to consume. Fluoride is the only chemical added to treat people who consume the water, rather than the water itself. Fluoridating water supplies can thus fairly be described as a form of mass medication, which is why most European countries have rejected the practice. However, personal, in-home, water treatment systems, such as a Reverse Osmosis or Carbon tanks or filters can be used to remove fluoride from water.
