"They were great to work with and more competitively priced than culligan. We were selling the home the water system was going into and needed to get the work done quickly before closing to address issues on the inspection report. They were great to work with and very responsive. We ultimately had installed a basic water softener, UV system and new sediment filter housing."

"I cannot say enough good things about this company. A power outage at our house over a weekend caused a lot of damage to various motors throughout the house. Joe called very quickly after I left a message (on a Sunday!) and went through a lot of possible things to check in order to try to save my paying for a service call (much appreciated). Ended up scheduling an appointment for 8 a.m. the next morning. He was here on the dot and quickly diagnosed the problem. Fixed not only that, but helped my husband get other things restarted as well (water filter and hot water heater) before he left. The best experience ever with a service professional -- I'd highly recommend him and Old Faithful anyone with well or well pump problems."

"John was great. He came and installed the water softener while we were without power. Then he came back when the power came on to show us how to use it. He was the only person that followed up after we got a quote."

"Everyone from the sales team to office staff and especially the actual plumbers that came out to do the work were exceptional. Let me say that I felt completely confident with everyone at Polar Plumbing from the beginning to the end. The installation of my AO Smith water softening system was done with the utmost care and professionalism. I'm very happy with the service received and the neat job done. I would absolutely recommend Polar Plumbing to anyone looking for great work and an excellent team of professionals for their home remodeling or repair work. Warmest regards, Joseph R Rivera (Home Owner)"

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"From first contact I found the office to be professional, courteous, and a pleasure to deal with. The prompt on time appearance of Joe for the estimate, the estimate itself, and the very polite men, Eric and Dylan who came to do the work were great. The job was done cleanly and in a timely manner and Eric made sure to show me and explain everything I needed to know about the system, including letting me know if I had an issue down the line, they are but a phone call away. I highly recommend Old Faithful Plumbing and I can say without hesitation, if I need any other plumbing work done from here on out, they are who I will call, Thank you, Joanne, Ashley, Joe, Eric and Dylan for such a stress-free experience."

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.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

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.

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.
