Customers say: Super punctual

"I was in need of a new water softener system and looked on Angie's list for recommendations and saw the outstanding reviews for Ohio Valley Pure Water. Contacted Mike the next morning and he was able to come out and take a look later the same day. I was very impressed with Mike's professionalism and knowledge. He had informed me of several things that I was not aware of while using our old system. His pricing was lower than the previous company we had used and I got more bang for my buck! After discussing all with my husband, we decided Ohio Valley Pure Water was the only way to go. We were able to get an appointment a week later for the installation of our new system! Both Mike, the owner and Greg the installer were both very professional and knowledgeable. Can't thank Greg enough, he did an outstanding job while replacing our old system and adding a water filtration system. I am 100% satisfied with my new water softener and water filtration system and would highly recommend Mike and Ohio Valley Pure Water!"

"Ken was the first plumber that gave us a reasonable price to install a shower tower. We didn't want to pay for a maintenance membership or to pay for someone's vacation house, we just wanted a simple plumbing matter taken care of. Ken was exceptional. He arrived on time, was very knowledgeable and explained every step of the procedure. We will definitely call Ken in the future for our plumbing needs. He also noticed that our pressure relief tank, for the hot water heater, was hanging low and had water inside it. It needed to be replaced and he was able to do that job too. Highly recommend!"

"We needed to check our water heater for leaks prior to closing the sale of our house.Joe Lay were out installing a new water heater and expansion tank the next day. The technician explained how all the components were supposed to work before checking everything so we both knew we needed a new tank as well. Outstanding, professional company. Billy was very respectful, knowledgeable and professional the entire time in our home. We would highly recommend Joe Lay and Sons for any plumbing needs."

"Tim (owner) was great to work with—professional, responsive, and very kind throughout the entire process. Jeff, the handyman who handled our plumbing, electrical, and general contractor work, was also fantastic. He was knowledgeable, easy to work with, and did excellent work. We’re very happy with the service and will definitely use them again in the future. Pricing was fair and much lower than other quotes. Highly recommend!"

Water Softeners FAQs, answered by experts

Hard water is not considered unhealthy and is safe to drink, cook with, and bathe in. It doesn't pose a risk to your physical health and can even help you get enough essential minerals like calcium in your diet. However, it can negatively affect skin and hair. Using hard water for washing can contribute to dry skin, an itchy scalp, and may worsen conditions like eczema by altering the pH balance. Additionally, some people do not like the taste of hard water.

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits 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 tools like Angi’s state licensing tool to verify an installer's license status.

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.

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.
