"Excellent job! Good Guy Plumbing fixed my leaking water heater quickly and thoroughly for a fair price. Spoke with Robert over the phone and David came out to do the repair. Both were professional, knowledgeable and kind. I recently bought a new townhome and will be doing business with them for any future plumbing needs. Many thanks to David, Robert and Good Guy Plumbing. It’s such a relief knowing there are good, honest plumbers I can count on."

"CARP is top-notch. Our water heater crashed, and we had no hot water. Number 1: Gaddiel gave me an estimate immediately based on pictures. Number 2: Jose and Ivan arrived the same afternoon and replaced my water heater. I couldn't be more grateful."

"Great crew and awesome service. I had a hard time finding a place interested in dismantling a rusty failed 10k steel water holding tank. These guys got it done quickly, cleanly and they were very nice and good about communication. Top notch!"

Water Softeners FAQs, answered by experts

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.

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.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.
