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

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.

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.

Soft water is better for your hair. The minerals in hard water can dry out hair, make it brittle, and leave a film on the hair and scalp that may cause irritation. Hard water also doesn't rinse out shampoo and conditioner effectively, which can lead to product buildup that makes hair look dull and limp. You may also find you need to use more shampoo to get a good lather in hard water.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

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.
