"Absolutely fantastic service!!! Jason did an amazing job installing our new tankless water heater, and the whole experience was smooth and stress-free. He took the time to answer all our questions, made sure everything was set up perfectly, and left the workspace spotless. You can tell he takes pride in his work. We?re beyond happy with the results and grateful for the excellent service"

"One could not ask for much more with Vlad from AWP. He was willing to take the time to discuss what he was doing and explain options. His work is very neat and precise and he maintained a very clean work environment. As someone who does most of their own work, I can assure you that I will utilize AWP for all my plumbing needs in the future."

"They worked with me on all steps. Everything explained fully. Told me the access they would need for all work well ahead of time and I was able to schedule the work time so I wouldn't be rushed in moving things. They gave me options, I selected the option that I felt worked best for me and they did it. On time, on cost. Cleaned as they went. Arranged their work sequencing so that we wouldn't spend a night without gas (for hot water and furnace). Nice people at all stages."

Water Softeners FAQs, answered by experts

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

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.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.
