"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"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."

"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"

Small jobs welcome

Hello,\nI’m Brian and have been an electrician for 35 years and over the years I have learned other trades and I just understand building and mechanical items and how they work. That promotes the way I take things apart and how they go back together. I look forward to working with you to start and/or complete unfinished projects.

"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!"

"I was impressed from the moment the owner introduced himself and his assistant to the time they left my home dirt and soot free. Not only did they do a fine job cleaning he also checked the dryer vent. Will call them again next year.

Water Softeners FAQs, answered by experts

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.

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.

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.

Hard water doesn’t hurt, but it might feel more abrasive, especially if you have sensitive skin. It’s also about how your skin feels after bathing. You might feel as though you have a sticky film over your body because you do—it’s all that soapy residue left behind because the hard water can’t rinse it off completely.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.
