"The experience beginning with Scott coming out to test the water to Jim installing the water softener tank and reverse osmosis unit was great. They are very professional and informative and the price was just right. I will highly recommend and will refer this company to any family or friends looking to improve their water."

"I just won a beautiful water heater from Legendary Service, and they were amazing. The installation was quick, easy, and clean. The owners came down personally to make sure everything went smoothly. Very nice people and I would definitely go to them for all my plumbing and heating needs!"

"Terrence Spranger was my plumber. His quote was fair. He was on time to the job. He replaced my hot water tank and shut off valve. He suggested placing a tray under the tank that has a drain hose just in case the new tank eventually leaks then it won’t run all over my basement. He had the model and serial numbers added to my receipt for insurance purposes. He was very personable and put the customer first. He went beyond what was expected of him to do. Thank you"

Water Softeners FAQs, answered by experts

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.

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

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.

A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.
