  • Thanks to Mermaid and this system we can live a normal water usage life! I wish I would have called them from the beginning!
    "This is long but worth the read if you have a low yield or low recovery well. Great experience with Mermaid Water Systems, especially Randy, Adam, Brad, and Patrick.

    I have a very low yield and low recovery (about 2 pints per minute) well. My old water filtration and softener system was put in by an “expert” in 2022. The way the system was set up, we could use about 8 gallons of water in the pressure tank before the well pump would come on, with a normal 2-5 gallon a minute well this would be fine. Due to the low storage capacity and very low recovery rate of my well we had to be very careful about water usage, especially on days when the filter and softener needed to backwash and regenerate. Even after the system was adjusted for short regenerations, the well ran dry several times. I finally said enough is enough and called Mermaid.

    I worked with Randy and we found a product call the “Well Manager”. It is essentially a large tank with a computerized control panel. The system replaces a traditional pressure tank. The control panel runs the well pump on a timer based on the well recovery rate. There are safety mechanisms, such as flow and pressure detection, and electrical amperage monitoring, that will shut the well pump off if it begins to over pump the well. Essentially the system “sips” water from the well and deposits it in the tank whether you are using water in the house or not. It will do this until the tank is full. Currently it is set up so my well pump runs for 40 seconds every 28 minutes when the tank is not full. The settings are easily adjustable to balance water intake and pump cycles. When the house needs water, it is drawn from the tank by a constant pressure pump. There is a sediment filter before it goes into the tank (not a concern to have it between the well and tank since the pump is operated on a timer instead of a pressure switch). After the tank, the water goes to a kinetico filter and softening system, then through a UVC light to the faucets/appliances. I can actually do multiple loads of wash, run the dishwasher whenever, do everything concurrently if I want. The well manager continues to refill the tank by “sipping” from the well around the clock. It automatically shuts off when the tank is full. I’m amazed, it saved me from drilling a new well where results are not guaranteed, I could have had the same low yield and recovery issues.

    Thanks to Mermaid and this system we can live a normal water usage life! I wish I would have called them from the beginning! The professionalism, clean easy to follow plumbing, and toleration of all of my (many) questions really set the Mermaid team above any other plumbers I have used in the past. Again, Randy, Brad, Adam, and Patrick were great, I’ll call them for all of my plumbing needs!"
  • Thank you Brent for the amazing installation! And no electric timer to worry about resetting when the power goes out!
    "I can't understand why anyone uses Culligan. Mermaid put a whole house softener in my restaurant after my second water heater blew up from scale buildup. Culligan had a softener in here but every time I called them, a different person showed up, charged me"

  • You will not go wrong having Mermaid Water in your home for ANY of your water needs
    "My first call to Mermaid Water was to Lisa she was so professional, and friendly. The price I got from Mermaid was less than half of another company. Kody came out first and tested my water and mentioned what he thought I should get. I did ask for more info and Brent came out and explained to me how things work and his thoughts. My next contact was with Becca who is also amazing she went out of her way to get the installation as soon as possible. Thus leads me to Jason. This man has amazing customer service. He explained everything and how to operate my equipment. Jason went way above and beyond what was asked and expected of the company. Jason took the time to treat my home as if it were his own. He even took the time to let my dog out to pee....... Jason spent hours and hours at my home making sure things were just right. After making sure things were exactly as I thought they should and only then the installation complete. Thank you, Lisa, Becca, Brent, Kody, and Jason Howard. You will not go wrong having Mermaid Water in your home for ANY of your water needs Thank you so much."

  • The service tech was gracious and knowledgeable
    "Terrific small company that sells Kinetico (hands-down-the-best) reverse osmosis drinking filter system. The service tech was gracious and knowledgeable, came out to Gambrills, MD within a couple of days to evaluate my water, and installed my new system within a week. Excellent service, very professional. Pricey, but I love everything about this "Cadillac" of RO units."

  • My water tastes great and my friends love drinking my water, they were so surprised at how clean it tasted.
    "

    I'm a health-conscious person and drinking clean water has improved my health. After much research, I discovered Mermaid Water and Kinetico. I've had Mermaid Water Kinetico for 8 years now and their customer service has been excellent. My water tastes great and my friends love drinking my water, they were so surprised at how clean it tasted. My representative Randy is a down-to-earth people person and is very helpful and knowledgeable. I would recommend them to anyone looking for better water and better health. If I could give them 10 stars if that were an option.

  • Solved my hard water problem in about 4 hours!
    "Solved my hard water problem in about 4 hours! The previous owner of the house installed a whole home filtration system, but it wasn't stopping the huge amount of chlorine or hardness from Spotsylvania County water. Nick, the installer, went over every section of the system to help me understand how it works, and how to maintain the system, which is minimal - open the lid, if the salt is low, add some more...simple. A small leak happened overnight and he was back the next day to fix it. I would definitely recommend Mermaid to my friends or anyone who is looking for a water-softening system."

  • It is rare to find someone as genuinely interested in what the customer wants and in ensuring everything is as expected before leaving. Thanks for the great work
    "First and foremost I want to acknowledge the Exceptional customer service from Russ, an installer/repair guy at Mermaid Water. Due to some special requests I had for my installation, I had to have installers out here 3 times. Russ was here the first time and did a great job and was extremely professional and very easy to work with. The second guy that came out was ok but didn't do the job right. I requested Russ to come out and fix the issue from the previous guy and again, Russ did a great job. It is rare to find someone as genuinely interested in what the customer wants and in ensuring everything is as expected before leaving. Thanks for the great work, Russ.

    Overall my experience with Mermaid was excellent and the water softening system I had added to my home has worked great. I had it installed over six months ago and would highly recommend Mermaid for others to use."

  • Knowledgeable and professional. Great service, would definitely recommend this company.
    "

    We have hard, acidic well water in our house and, as a result, have had numerous problems with our well and our water system (plus every appliance in our house that uses water). Our water stopped working last night--AGAIN--so we called Mermaid. They sent out a technician first thing this morning. He did a thorough check of our water system and found that the well pump is not working, so we will have to call another company for that service. Mermaid's technician, Nick, was knowledgeable and professional and explained each check he performed. He took a lot of time to diagnose the problem but did not charge a service fee since he wasn't able to correct the problem. Great service, would definitely recommend this company.
