"SuperHandyMan was very responsive to my needs. Our 22year old water heater needed to be replaced. Once a scheduled time was agreed, the service was fast and efficient. Of all the companies contacted, the price was the best. 5 stars!!!"

"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!"

"The water line for my fridge cracked and it was raining in my basement. They were quick and responsive to coming out and performing the repair. They also said part of a nearby gas pipe was corroded as the leak had been ongoing and recommended replacing it as well. They came out the next morning and performed that repair. Cost was very reasonable for two site visits, labor and materials."

"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."

"Great to work with. Told me what their thoughts were and gave an honest assessment. Essentially recommended I didn’t need to do the work I thought I did but because of their honesty, I’ll be looking to hire them the next time I need their service!"

FAQs for water heater repair or service projects in Chesterfield, 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.
