Their ‘customer service’ is awful and the women who work there are completely inept... STAY AWAY!!!"

Atlantic Water Products offers a wide variety of home water treatment systems and air purifier options for residents of Philadelphia, Southeastern Pennsylvania, Central and Southern New Jersey, and Delaware who want better quality water and fresh air for their families. We have been serving local homeowners since 1987 by offering superior products that will last for years. We also focus on addressing the specific needs of our customers and providing customized solutions, with an individualized approach that begins with our complimentary in-home water testing service.

"Do not be deceived by this scam. We thought we could trust Home Depot back in 2015 when they offered us a free water test after we bought our first home. Lo and behold it was a LENGTHY sales pitch using psuedo-science that played upon the vulnerable situation we were in at the time (one of us was having frightening chronic health problems that were getting worse by the day.) We were not allowed to have time to think about our decision and were told our water was bad based on a psuedo-scientific magic trick. Could we get back to them tomorrow? No the decision had to be made that day. To the tune of $7,000. Oh but they were throwing in so many freebies for us! Come to find out this system is only worth a few thousand dollars. Fast forward five years and we have to pay HUNDREDS per year to maintain this system. Additionally, all along the customer service of the distributer, Atlantic Water Products (AWP,) has been atrocious. Very unprofessional. We have to call 3 and 4 times to get a call back. We are clearly low priority now that we've bought the system. We moved recently, to a home that is a 2 minute drive from our previous home. Our first appointment to have the water system removed was canceled only hours beforehand. So we had to leave the system and then arrange with the new residents to have it removed by AWP a month later (which was the soonest we could get.) AWP does not allow same day removal and installation. You have to call them again once the system is removed to schedule installation. BUT they don't call you back until you've called 3-4 times. So we weren't able to get a re-installation scheduled for another month. When we finally got them on the phone they told us that since our system had been sitting for over 24 hours we now were advised to pay an additional $700 for new filters... keep in mind removal was $300 and installation will be ANOTHER $300. So we have to pay $1,300 to move this system, $700 of which we have to pay only because they don't allow same day installation!! The unprofessional way the company is run as well as the scammy way the sale went down has really made me question whether this product is even legitimate. A few years back I grilled one of the customer service people repeatedly to find out whether the system filters our lead. All I ever eventually got was a one sentence email saying "yes it filters out lead." No NSF certification, no "this is how it works" etc. Last year when the technician was installing replacement parts I saw that one of the under-sink cartridges had a new label with just SO many psuedo-scientific claims on it- It said it prevents cancer!? The only thing I will say is that the technicians have always seemed professional. But no one told us when we moved our system that it couldn't sit for longer than 24 hours. No one told us about the risk of bacteria. When we called to complain Gus Pfaundler, who runs the service department at AWP told us HE was disappointed with US! For not wanting to be scammed I guess? Please be aware that multiple lawsuits against Rainsoft and Home Depot for this scam have been filed and won. Please be aware there are other products that do the same thing and are cheaper. And don't be naive like we were when we were scared for our health and desperate- if someone tells you you can't take a day or two to think about whether to buy something you have to stop and ask yourself what they are afraid you will discover in 24-48 hours of research."

Water treatment & purification system installations and replacements FAQs

Water softeners consist of three main components: a mineral tank, a brine tank, and a control valve. In some smaller units, the mineral tank and brine tank are combined into one cabinet.

Professionals install whole-home systems at the point of entry of the main water line. Smaller units are installed under sinks or near a washer—these units only soften the water for that fixture, not the entire home.

  • Mineral Tank: Hard water passes into the mineral tank through resin beads, and an ion exchange occurs. Magnesium and calcium ions are exchanged for sodium or potassium ions from the brine tank.

  • Brine Tank: The brine tank contains sodium or potassium to recharge the resin.

  • Control Valve: The control valve determines when to clean the resin beads.

Choosing between a salt-based or potassium-based water softener depends on your priorities. Salt-based systems effectively remove hard-water minerals, regenerate efficiently, and are cost-effective. However, they may not be ideal for individuals on low-sodium diets. Potassium-based systems neutralize minerals without removing them and regenerate more frequently. They are more expensive but offer a healthier and more environmentally friendly option. If sodium levels are a concern and cost isn't a major factor, a potassium system may be the better choice.

To calculate your water softener's capacity, determine your grains per gallon (GPG) number by:

  • Multiplying the number of people in your home by 90. The average number of gallons used per person for washing, drinking, and cooking ranges from 80 to 100 gallons per day.

  • Multiplying that result by the hardness of your water. The average grains per gallon in the United States is 10 but can range from 0 to 17. You can find your GPG number by purchasing an at-home water testing kit.

Installing a water softener takes between two to four hours on average. The exact duration depends on the complexity of the unit and whether additional plumbing or electrical work is required. If modifications to existing pipes are necessary, installation may take longer. Preparing the installation area by clearing any obstructions can help streamline the process.

Water softeners can last up to 25 years with proper maintenance and care. The lifespan depends on the type and quality of the unit you choose. Single-tank electric water softeners may last around 12 years, while higher-quality models tend to last longer. Regular maintenance, such as routine inspections and timely replacement of salts or potassium, helps extend the life of your system. Most water softeners require minimal repairs over their lifespan.
