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.

For this very happy new customer in Washington, DC, we installed a Reverse Osmosis System for up too 99.9% contamination free drinking water, a Water Softener with Brine Tank for hard water, a Carbon Tank to remove smells & odor and Sparkling Water on Tap! Of all the work we completed on the house, the Sparkling Water on tap is far and away the system the customers enjoying the most.

While we support clean water and water treatment for all, nothing says that clean water can’t be sparkling!

If you would like Sparkling Water on tap in your home, we are more than happy to be of assistance!


Ensuring clean, pure, fresh drinking water is our passion. Every Water Treatment System we install is specific to that customers water wants & needs.

We test the water quality of every house we visit. Based on those findings we recommend water treatment and purification specific to those findings. From Water Softeners for hard water, Acid Neutralizers or Chemical Feeders for pH & corrosion control & Reverse Osmosis Systems for up to 99.9% contaminant free drinking water. 

In addition, we install & service Radon in Water Mitigation systems,  Ultra-Violet System’s to remove bacteria from water and Sediment Filters. As well as, Pressure Tanks, Well Pumps, Carbon Tanks for odor, Constant Pressure Systems and so much more. We design water purification specific to you and your well. Water, it’s what we do!



A Reverse Osmosis (RO) water treatment system will remove up too 99.9% of all contaminants from water. Providing safe, potable drinking water for you and your family. Equally as important, you will never have to buy bottled water again. Healthy living and saving the planet at the same time.

The price of a fully installed Reverse Osmosis is roughly the same price the average family spends on bottled water each year. Stay Green in 2019!

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. Call National Water today to have your water tested.

For over 40 years, our no water division has been installing and maintaining well water pumps. Using only top quality and non-proprietary well pumps, conduits, casing, wire as well as pressure tanks and more. 

One of our most important jobs is emergency response.  No water, low pressure or any leak or flood, we are here to help,  7 days a week, 365 days a year. Whether were dealing with current or new customers, businesses or home warranty companies, emergency service is always a top priority. 

Each and every week our emergency  well water response team replaces old or broken well pumps. In addition, we repair or replace water logged pressure tanks and broken control boxes for a constant pressure systems. As well as thousands and thousands of feet of broken, old or corroded well pipe and wire.

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. 

Do you have low water pressure? Are you and your family constantly running out of water? Call National Water to learn about our Constant Well Water Pump and Control Box Pressure Systems. With a new Grundfos Constant Pressure System you control the pressure with just the touch of a button! Constant Pressure systems can provide water that has more pressure potential than city water! Take control of your water today! 

We are prepared for any well pump or well water situation! If you have no water, low pressure, leaks or floods, please contact National Water at 301-854-1333 or by email  at


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.

National Water technicians are prepared for any water situation. To stay prepared, we hold company wide continuing education meetings every Tuesday morning. We discuss new products in water treatment & well pumps as well as round-table ideas for specific customers water issues. 

A new customer called complaining about their very low water pressure. Our emergency response team was dispatched to evaluate the situation. The customer had an existing Water Softener, Acid Neutralizer & Reverse Osmosis system. The existing equipment hadn’t been serviced in years and as a result, additional testing was required. We tested the water, as we do for every home, for contaminants such as radon, bacteria, lead, pH and more. The Radon and E.coli water tests failed and as a result new equipment was proposed and installed.  

The existing softener and neutralizer were dumped and re-packed with new resin and calcite. The Reverse Osmosis filters and membrane were changed and the faucet and housings were cleaned. Annual service is always recommended for all water treatment systems. 

In order to remove the radon from water, a Spruce AiRaider was installed.  An AiRaider removes up to 99% of radon from water through a multi-stage aeration process.  We installed an Ultraviolet treatment system to remove up too 99.9% of bacteria from water.  

In addition, we installed a sediment filter, water heater and well pump control box.  Well pump control boxes provide consistent and controllable water pressure.  The water treatment equipment was moved into a new room behind Leak detectors and water isolation barriers.  Our very satisfied new customer now has clean and safe water for her entire family to enjoy!

We pride ourselves on installing only the best non-proprietary equipment on the market. This allows customers flexibility in their water treatment choices!

Yesterday, we removed some old proprietary water equipment for a new customer in Clarksville, Maryland. We installed a new Chemical Feeder with Grundfos Pump for pH and corrosion control, a new Water Softener with a Clack Valve head and Brine tank for Hard water, and an Ultraviolet  Water Treatment System to remove 99.9% of all bacteria from your water as well as a Whole House Sediment Filter. Below are some before and after pictures!


A lot of people either do not know or understand what Water Treatment equipment they have and what each systems purpose is. The two systems most commonly installed are an Acid Neutralizer and a Water Softener.


A Neutralizer and a Softener work together to balance the pH of your water. Most importantly, they remove unwanted contaminants from your water.

The Neutralizer is designed to raise your pH using a food grade calcium, called calcite. As water passes through the unit, it dissolves the calcite and the water becomes neutral.  This helps in eliminating corrosion of your plumbing and appliances. However, a Neutralizer can sometimes raise the pH more then the desired amount. 

In order to find and maintain that perfect pH balance 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.

All of our Neutralizer’s and Softener’s are installed with Clack Valve Head’s that regulate and monitor the amount of water passing through the system, when the Softener needs to backwash (clean the resin) as well as when service is required.
