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.

Great service in a time of need. They were life savers as my hot water heater broke and they were able to replace it in literally less than 24 hours. Amazing service and amazing tech.

It’s been several months now since National Water Service installed our new water softening system. Our place had started showing its age when I started finding water leaks popping out from our old copper pipe plumbing. Very scary! Happily, I learned of NWS and our new water system quickly solved that very BIG PROBLEM so common in older homes with copper plumbing. And our new water works from NWS also softens our well water, it balances the PH and basically, rejuvenate this old house. From my first call thru to the final installation NWS was nothing but always professional, honest, and prompt and reasonably priced. NWS has more than earned a 5 star rating, just an outstanding company!!!

Excellent pre and post installation support. They explained everything very well and were transparent in scope of work and pricing. The crew showed up on time, were meticulous in their work, comprehensive in their training on the new water purification system, and left the space cleaner than when they found it. They delivered what they promised and this was a very smooth project from start to finish.

Great Service. Just had my backflow installed for my irrigation system. I had the pleasure having Joe as my technician today. What a great young man. He is the epitome of what an employee supposed to be. He really represented National Water Service well. For that, I will call upon them again when their services are needed. Thank you Joe; job well done! Vince

National Water Service replaced my old outdated well water filtration and conditioning system with a more reliable system that is easy to maintain. I just had them drop-off 4 gallons of Sodium Hydroxide that I add to the chemical tank. This tank greatly helps to maintain my pH at 7.0 (an ideal neutral water setting). They deliver the chemical for free and provide a handy carrying case for managing the 4 1-gallon jugs. Their technicians are very knowledgeable and helpful, both in person and over the phone when you have a question. I highly-recommend their services.

We had a sudden problem with our well and National Water service was able get someone here quickly as we had no water. They fixed the problem and we appreciate the quick response and repair. We have been a National Water service customer since we bought this house and highly recommend them.

Why work with our maryland water treatment company

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.

SAFER, CLEANER WATER

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.

ELIMINATE WATER ISSUES

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.

LOW MAINTENANCE

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.
