"Amazing Install and Service. Turn around time to get us on the schedule was quick and even came back out the next day for a minor leak that needed to be addressed. As a veteran I truly appreciate the service this Vet Owned business continues to give the community at a fair price. Installers were friendly and answered all questions we had and even did a basic training on our new water softener system before leaving. You need better water...look no further! (and ask about the veteran's discount 😉)"

"Josh and his helper did a great job plumbing in our new construction home, including putting in a whole home water purification system, and a 400 gallon holding tank since we live on a high ridge. Love how our house has turned out and they are hard workers!"

"Had water leak that presented in basement shop. I traced to upstairs bathroom and thought leak was coming from tub/shower supply. David quickly determined that the problem was actually a leaky toilet fill valve and corrected the problem quickly and to my satisfaction."

Customers say: Quick response

"Dan Toth was very knowledgeable, professional and guaranteed us that he would stand behind his product and what he told us he would do. He was prompt and didn't take up a lot of time giving us a "sales pitch". We were impressed with him and his product. If you need water treatment (and who doesn't if you live in and around Bristol) I highly recommend Mountain View Pure Water!"

"Did an absolutely amazing job. Not only did they check up on my HVAC unit, but they gave it a nice wash and cleanse. They also patched up the holes in my duct in the crawl space and gave hooked up sensors to test everything. Did I mention they gave checked on my water softener as well? All for $100, great service for cheap! Very professional and friendly."

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.

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.

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.

A good hardness level for drinking water can vary based on personal preferences, but an ideal level is 3.5 to 7 GPG. This means your water isn’t soft or hard. However, some people prefer the “fresh” taste from the minerals in hard water, while others like the smoother, “slippery” texture of soft water.

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.
