"I claimed one of the “2 Toilet Tune-Up” Angi’s special with 4 Service Pros (Snell). When I contacted Snell I talked with a very nice lady who scheduled me to get 2 plumbers to come out the next day from Noon - 4pm. I was told they would call 20 minutes to 30 minutes before hand to let me know they were coming. I waited from Noon to 4:05pm, never received a phone call, and so I called Snell to find out if my plumbers were still coming. I was told that there was an emergency situation in Chantilly, VA, that required my 2 plumbers to go to Chantilly instead of my place that morning. I understand emergencies do happen, but Snell knew that my plumbers were needed for that major Chantilly, VA, leak from the morning. They should have called me once they found out that my assigned plumbers would not be able to come out to my place within my scheduled time appointment. I should not have had to wait from noon to 4pm and then have to call them to find out that they were not coming. I rescheduled with them, and set another appointment for the next day The next day Brandon Thomas came out, and he was outstanding. He is very friendly, professional, knowledgeable, efficient, and a very good plumber. My problems turned out to be quite different than I originally had thought and he explained my options. I went with the option that he recommended and am very happy with the results. He also gave me discounts to help make-up for my inconvenience for having to re-schedule the appointment. I definitely recommend Snell (4 Service Pros) to all my friends and family."

At National Water Service, we set the standard for home water treatment, purification, as well as a complete line of well pumps, boosters, etc. In dealing with Residential areas, one of the important things a homeowner needs to consider is water quality.

Water Softeners questions, answered by experts

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

Yes, it’s fine to drink softened water. However, if you follow a low-sodium diet or have high blood pressure or sodium-related health concerns, make sure to speak with your doctor beforehand. If they advise against drinking water that’s been softened with sodium, you might be able to use potassium in your water softener instead.

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

Just as hard water can wreak havoc on your skin by drying it out, it’s also not great for your hair. That’s because hard water won’t rinse out shampoo and conditioner as effectively as soft water can. All that product buildup isn’t good news for your hair, which can look dull and limp over time with hard water.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.
