"The whole project went very well. They helped tremendously from start to finish with several ideas & advice. They ran into some unseen problems with the floor repair but were able to work it out & come up with a good solution. We are very pleased with the final results & would highly recommend their work.

"Scott and Grant came to our rescue when we moved into a pre-owned home. Replaced the water heater, put in a sink and new stools. There were so many issues but they were taken care of for us. They came as strangers and left as friends. We are so pleased with what they did."

Water Softeners questions, answered by experts

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.

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

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.

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.
