At National Water Service, we set the standard for home water treatment, and purification, as well as a complete line of well pumps, boosters, etc. If you need it, we have it! In addition to offering outstanding service and workmanship, our staff is friendly and eager to answer any of your questions.
In dealing with Residential areas, one of the important things a homeowner needs to consider is water quality. Before any decision should be made, a well informed homeowner should have his/her water evaluated. It is important to note that whether on City Water or a Well System, water quality can vary quite a bit from neighborhood to neighborhood.
National Water Service is happy to do a basic analysis at no charge. And if extensive testing is deemed necessary, we have water testing services available for virtually any contaminant at a reasonable rate.

Shari Hammond2024-09-23Trustindex verifies that the original source of the review is Google. Thorough, polite and professional. I loved working with this company! From 9/19/24 Unbelievable experience. We had 2 other plumbers come and claim to have fixed the problem. We got Dave’s name as a referral from Kendall’s Hardware. He’s a master plumber and he truly is. He did a thorough examination of the problem and came up with a plan. They followed through with that plan a week or so later (it was a two day) it was successful. The best part was how he listened to us and didn’t assume he already knew. He is a brilliant plumber and the company is wonderful to work with. Very professional. I’m very grateful. Thanks National Water! Dawn Richardson2024-09-23Trustindex verifies that the original source of the review is Google. I highly recommend National Water Service! Our representative, Heather and our installer were awesome. Heather explained the equipment I current had, any issues she identified and explain solutions and why she was suggesting them. She was great. I had additional questions after she left, and she responded immediately. Our installer was very though in explaining the installation, the maintenance that is needed and how everything worked. I really appreciated the time both of them spent with me and am glad I hire them. Rich Gibson2024-09-23Trustindex verifies that the original source of the review is Google.

The techs who came out to our home were super professional and communicative about what they were doing and why. They gave us a detailed overview of all the components of our home water system and educated us on how to best maintain our system between annual visits. Very satisfied with our experience! Helen W2024-09-18Trustindex verifies that the original source of the review is Google. I called on a Sunday afternoon after my well pump quit working. John answered the phone and someone was there within an hour. Daniel carefully assessed the situation and determined that my well pump was not functioning. He then went on to see if he would be able to make the repair. After determining what would need to be done is to replace the water pump, he let me know that he would have a crew at my house first thing in the morning. They notified me that they were on their way before 9am the next day and by 12:00pm my was water flowing. I’ve been a National Water Service costumer for 25 years and that will continue. They are timely, professional , and their employees are knowledgeable in service and repairs. If you’re on well water and want to improve the water quality and maintain your equipment call National Water Service. Chris Shim2024-09-17Trustindex verifies that the original source of the review is Google. National Water Service texted an estimated time of arrival. Dedicated workers explained the process, answered all questions, and completed all work in a timely manner. They were very professional and put on boot covers to keep my floor clean as they entered the home! Fantastic job by National Water Service to provide me with clean water. I recommend them for all water treatment, well pump, and plumbing needs.
National Water Service offers virtually EVERYTHING water treatment related. There is no problem too large or too small that we can’t handle. And for the most part, we handle problems using non-proprietary systems. Non- proprietary water treatment systems usually means they cost a bit less and rarely become obsolete.
Our water treatment specialists still service systems we installed over 30 years ago for that very reason! Expensive dealers with proprietary systems could never live up to those standards. If you buy from those guys, keep reaching for your wallet as the years pile up.
Does neatness count for you? All of our systems are carefully installed for simplicity and straight lines. If we can make it easier for you to do mundane tasks like changing a filter or adding solution to a tank, we’re going to make sure that we make it easy for you! Never call a plumber for the job a specialist can do better.
Whether you need a new well pump, a constant pressure system, replacement parts, or a new trench dug, we’ve got you covered.
Additionally, we’ve got the tools most other professionals don’t have. The latest in well cameras, underground line finders, pump hoists, and any and all equipment to make sure your well is running at peak performance. And if you have a low yielding well, no problem, we know how to handle those too.
When you hire a company with the right tools, the job gets done faster and for a lot less than a couple of plumbers yanking up a line and taking all day to do it. Never call a plumber when you can call a specialist!
After many years, we have added general plumbing to our lineup of services offered to the public. We held off for 40 years despite pleas from our customers for us to become their one and only water services company. With a new master plumber on staff, we can now handle just about any plumbing or gas related job.
Re-doing a kitchen or bath? Need new gas lines for outdoor grills or generators? Water Heater trouble? Call us!
Not sure what’s in your water? We offer everything from free basic water quality tests to in depth contaminant specific testing like Radon, Lead, Nitrate, Bacteria, E. coli, Coliform, Pharmaceuticals and much more.
Without having your water tested, it can be difficult to determine if you need water treatment or purification and what type of system works best for your specific water wants and needs.
National Water Service is here for all of your water heater needs, from repairs, replacements, and installations! Whether you have an electric water heater, a gas water heater, or a hybrid water heater, our team of professionals knows how to service, repair, and install each variety for perfect home safety and comfort. We are the experts in proper installation, and have the tools needed to be sure every gas connection is completed correctly and each electric installation is energy efficient.
Efficiency levels in appliances are advancing rapidly, which means even a well-working, aged water heater is still costing you in energy savings. Don’t wait until your water heater has completely stopped working before calling the professionals, have us check out your water heater ahead of time to ensure you are getting the best product for your home at the best rate.
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.
Undoubtedly, the top benefit of installing a water treatment, purification, or filtration system is that you will have safer, cleaner water that will benefit the health of you and your family members.
The primary reason to install a water treatment system is to remove dirt, sediment, radon, bacteria and any of the other 18 million contaminants that can be in your water.
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.
A quality water treatment system can last decades and should require little to no maintenance to the homeowner.
We do however recommend, to prolong the life and efficiency of your system, to have annual maintenance completed by a certified water treatment specialist.
