"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."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Tom did a great job fixing my water pressure issue. He back flushed our softener and holding tank, and re-pressurized the tank; all at an affordable price. He was just what we needed and I highly recommend him to anyone with water issues."

"I decided to go with Cassidy because out of the 4-5 different companies I contacted, they were the first to respond in a timely manner and their dispatch fee was affordable ($79 vs >$100). The actual service they provided went well. They were on time, finished the whole project within a couple hours and were professional. However, I did remove a star from my rating because they do overprice everything. I was able to cut down my total cost by >$300 by just buying my own supplies (ex: water faucet, basket strainer, faucet aerator, etc.). They were going to charge me $125 for something I was able to get for $4 and fix on my own, which I thought was ridiculous. Overall, I would recommend because they made the whole process go smoothly but I would just be aware of their pricing and make sure they don't trip you off."

"Ralph was our first call once we submitted what we needed. He was professional, happy to answer any questions and head right over to take a look for himself. He sent me a quote for review, and after getting similar prices from other providers we decided on HV Water because Ralph made my husband and I comfortable and as if he was doing this on his own house. The install day was spotless, both installers were professional, meticulous and thorough. Cannot recommend these guys enough. Thanks again for an amazing job."

Water Softeners FAQs, answered by experts

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.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

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.

It’s unlikely that hard water on its own could cause substantial hair loss or damage, though it’s true that bathing in hard water can cause your scalp to feel itchy or flaky and might dull your hair’s natural shine. Using high-quality shampoo and conditioner or buying a whole-home water softener can decrease these issues.

The most effective way to fix hard water in your shower is by installing a whole-home water softening system. This system treats water as it enters your home, removing the minerals that cause hardness before they can reach your shower or any other fixtures. While this is the most comprehensive solution, other methods are often temporary fixes. For a more affordable and shower-specific option, you can install a water-softening showerhead or a shower filter. However, these filters are generally less effective and may not remove all the contaminants that lead to limescale and hard water stains. By implementing a water softening solution, you can expect a reduction in mineral deposits and enjoy the benefits of cleaner-feeling hair and skin.
