"Mr Sam did a wonderful job removing a bad water heater and installed a new one. He also reconfigured my plumbing under the kitchen sink and installed a new sink and faucet. He was on time, polite, patient with my son who asked a million questions, and left a tidy workspace when finished. I am excited to hire him again for my many other projects that are needing done. I highly recommend this company."

"I called Mr. Rooter because I had called another Plumbing company to come out the night before and they were a no show.  They were extremely friendly over the phone.  I called at approx 8AM and said they'd be able to come out by 11AM.  They called at about 9:30 to say someone was available to come out now and I said that was perfect.  They arrived at 10AM.

Jason was the plumber who arrived and he was very very friendly and professional.  I told him the problem and we discussed pricing up front.  I had a coupon which he said they would definitely honor.  He immediately got to work.  He wore footies over his shoes while in the house.  He worked diligently and answered all of my questions.  After about an hour and being certain the line was clear he cleaned up, we took care of payment which was exactly what was discussed beforehand, and he was on his way.

A very pleasant and hassle free experience.  I will definitely be calling Mr. Rooter for the Franklin County area again for any plumbing needs and would recommend them to anyone needing this kind of work.

The job also comes with a 30 day warranty which I thought was great and definitely put my mind at ease just in case something happened again."

"DP showed up a few days after phone contact to inspect scope of work. They submitted a bid a few days later, and started work a few days after that. All interior plumbing as well as excavation & backfill for exterior run to propane tank was completed in two days. A customer-instituted change from original plans was completed a few days later. Crew was professional & polite. Work looks good to this fussy engineer."

"I called Tap Heating and Cooling early Sunday afternoon.  John was at the house within an hour.  He explained to me what the problem was and how it could be fixed.  He left to go get parts and was back within the hour like he said.  He assured me he wasn't leaving until I had heat.  When he left I had heat.  Thank you John.  In the future Tap has won my business.  Nothing but professionalism, honesty, and courteousness was shown.  Great customer service.  You will be hearing from me in the near future.

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"We had a very good experience with our Bathroom Remodel. Basically, the bathroom was gutted. Dylan was the representative that helped us through the design process. He brought all samples to our home to make choices. He was patient, knowledgeable, and overall, very pleasant to work with. Ben and Kellan performed the work on the project. They were very professional, and extremely hard working! They literally took lunch breaks and other than that worked the entire day without breaking. They were quiet as can be, they didn't have any music playing or even receive private phone calls. They cleaned up after themselves each evening before they left. Extremely pleasant to have in our home. They kept us informed along the way and paid attention to detail. We couldn't be happier with the end results, job well done. I would definitely recommend them or use them again. Steve & Debbie K."

"A very professional, customer service oriented company. The technician was extremely skilled and knowledgable in his trade. Out of three appliances I scheduled for repair, he had the parts with him to repair two of the appliances same day and returned with the 3rd part at my next eariest convenience to repair the 3rd appliance."

FAQs for water heater repair or service projects in Union, MO

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
