"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

"I would echo most of what I have read in the reviews about Brian. He is prompt, courteous, and professional. Though he is a bit on the expensive side, I believe he is well worth it. An honest, experienced plumber is like money in the bank as far as I'm concerned. Because, while I could have found someone less expensive, experience has shown me that when it comes to plumbers, you definitely get what you pay for. And Brian is worth every penny."

Water Softeners FAQs, answered by experts

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.

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet. 

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.

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.

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.
