"Rick advised me via text message what to do to get the system up for a soft restart right away. Then he came to my home, tested my water, and made all the necessary adjustments to make sure the system was working properly. I didnâ t buy the original system from Rick and now I wish I had. I high recommend him!"

"Not good. The water leaks had caused black mold that had to be repaired. When repairs were completed 3 months later, the valves still leaked from the stem when turned on. It was past 60 days so I had to pay another $100 service fee to have the water leaks fixed. He tightened the packing and quoted $350 to replace the valves. Sheesh."

"Originally I contracted with him because we had a lot of water in my basement.  The water was pretty high.  I had a few people off of Angie’s List come look at it and they were giving me estimates between $20,000 to $25,000.  The guy who came in from Concrete Raising gave me some good advice.  He told me not to start with an expensive solution.  He told me to try the sump pump first and see if it would work.  It seems to have solved the issue and it only cost me $4000.00."

Water Softeners FAQs, answered by experts

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

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.

Generally, it is safe to bathe in yellow water, as the color is often caused by iron, tannins, or rust, which won't harm your skin. Soap will still clean you effectively, though the water might leave stains. However, if the water has an unusual smell or you suspect contamination, avoid bathing and contact a plumber for an inspection. A professional can also help if you find bathing in yellow water problematic and want to determine how to get your water clear again.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.
