"We also entertained a bid from another company that opened our eyes. Everett Was honest, candid, and realistic about what could be done. Where as the other company was vague, and used hard sell tactics. We were impressed when Everett brought in a kit to test our water, even though he had expressed concern that we may not have room in our laundry room for a water softener. Whereas the other guy made no effort to test anything, but told us a uv light unit couldn't properly do its job on our well water w/o a water softener unit. Naturally that was my first question for Everett. He said no, the light had a filter, and the hardness of the water had nothing to do with it...NO UPSELL. The other guy was very vague about pricing, but said we needed to lock it in because things are so crazy right now, it could jump thousands of dollars. That guy finally gave me an estimate between $3000-$6000. Quite alot of wiggle room there. EVERETT ON THE OTHER HAND, was open and honest about cost from our first conversation. His son, Austin showed up early, did a great job, and was very patient explaining things to us. So if your looking for a company that knows what they are doing, and relies on honest realism to sell there product, Jones Air and Water will take good care of you."

"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"Sam Marsala was very good at diagnosing my furnace trouble, the fix was simple to my relief. My water heater was on its last legs. Sam diagnosed the trouble and we had Sam install a new Raheem water heater. He was very quick to respond to my needs and explained very clearly the trouble found. Installation was really done neatly and he left the work area very clean. I am more then satisfied with the work, product and technician. Well done."

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"DP Plumbing and his crew went above and beyond to make sure that this job was done correctly and for the most reasonable price possible. They were professional efficient and got the job done as quickly as possible. I would highly recommend this company to my friends and family and to anyone else who wants a fair price and a professional team working at your home. I had other people come out and give me bids and none of them gave me the Comfort level that this company did. I just trusted them. I am actually having some other work done and have their card because I'm going to give them a call back for sure."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

"Mayo Plumbing is different from all the rest. They use data and research to inform their work. Before calling Mayo I had two different plumbers look at our new (very old) house. The first said, "St. Louis has hard water - you NEED a water softener." The second said, "St. Louis has great water - you DO NOT need a water softener." Mayo said, "What did the test results say? No one can tell you you need a water softener without testing your water first." BINGO. They tested our water and determined we DO NOT need a water softener. Same approach for our broken shower. The mayo plumber actually researched the issue, spending time with the paperwork and on the phone with the Kohler rep to determine exactly what we need to do, before making a wild guess and upselling us. I've never seen a plumber like this - these guys are SMART and will be our go-to provider!"

Water Softeners FAQs, answered by experts

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

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.

Generally, it is safe to bathe in yellow water, as the color is often caused by iron, tannins, or rust, which won't harm your skin. Soap will still clean you effectively, though the water might leave stains. However, if the water has an unusual smell or you suspect contamination, avoid bathing and contact a plumber for an inspection. A professional can also help if you find bathing in yellow water problematic and want to determine how to get your water clear again.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

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.
