"We were so fortunate to find American Plumbing and Sewer, LLC! We had a quote from someone selling water softeners for $12,000, and we thought, â there has to be another much less expensive option out there!â With Lannyâ s company we got a system of much higher quality that cost 1/4 of the other personâ s quote. Personable, reliable, honest and wonderful customer service are words that describe American Plumbing and Sewer."

"Pure Water beat the other contractors on price and what we received as a product. We couldn't be happier with the installation. We now have hot water on demand on the opposite side of the house where it could take 5 min of water running for the water to be hot. Pure Water also installed a water softener and now our hard water is soft! Patrick who did the install was professional, personable, picked up what little mess there was, explained everything once the install was complete. We are so pleased we have them on the hook for a fireplace gas line and will have several bathroom projects going forward. We could not recommend Pure Water Services more. Thank you"

"I would highly recommend this company! My service pro was knowledgeable, friendly, and efficient! He took on an old, leaking, rusted water heater job that was not for the faint hearted. He problem solved every odd glitch that my older house threw at him. The whole experience was completely positive!"

"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon. An EXTREMELY short time compared to our last water heater issue. Highly recommend Heart and will use them from now on."

Water Softeners FAQs, answered by experts

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

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. 

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.

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.
