Posted on Google Elizabeth EubankTrustindex verifies that the original source of the review is Google. Had the opportunity to have Plumbing Innovators out for a suspected leak. Matt and his co-workers were very good. After many holes in the walls, they successfully found the leak. They never gave up, were very efficient in getting it fixed so water mitigators could come in a do their job. They listened to all of my questions (I had plenty) and answered without hesitation, and never like I was bothering them. I would definitely recommended they to my family and friends.Posted on Google Statues Of PovertyTrustindex verifies that the original source of the review is Google. Here is another honest review...this is for Plumbing Innovators and their team of honest and professional technicians, installers, office personnel....especially those I personally had the absolute pleasure of meeting and conducting business with, Thomas, Austin, Dillon, Hunter, Carol and Angel. These folks were friendly, knowledgeable, attentive, and honest. Which is something that really rates high in my book. I had used Plumbing Innovators twice in 1 week, first was a burnt up septic control box that needed immediate replacing...then 3 days later I was in need of a new water heater...not just any water heater, mine was propane and was a special kind that was super expensive. Plumbing Innovators, gave me their FREE estimate on both water heaters, propane versus electric, and we decided the better option was much cheaper to convert propane to electric. Which, in my opinion, shows they were not in this to rake in the most money, they genuinely cared and sought to make the best decision. This shows character and integrity. When it came time for the septic power/alarm box to be replaced, I was shown step by step why and how it needed to be replaced. Not only had it burnt up and caused an alarm that could not be reset, but the unit was extremely out of date using baseball sized lead counter weights for the floats. The warranty that Plumbing Innovators have on all of the items that I have had replaced are matched by none. The technicians were prompt to arrive when they said they would. They also call ahead to ensure that the customer is available. They have extremely competitive pricing, great warranties, fantastic customer service, new and up to date materials/appliances...all because they want the best for their customers. I most definitely recommend Plumbing Innovators and I will continue to use their services. Extremely satisfied customer here. Thank you, Thomas, Austin, Dillon, Hunter, Carol and Angel....you guys ROCK!Posted on Google Diane ClarcqTrustindex verifies that the original source of the review is Google. Same day service, thorough, pleasant and prepared. Highly recommend!Posted on Google susan tylerTrustindex verifies that the original source of the review is Google. I highly recommend Plumbing Innovators. The Professor (TJ) and The California cutie (Matt Smith) always listen and respond with upmost respect. Everything works beautifully once the problem has been resolved. They will willingly return to answer any questions that I might have about future plumbing jobs. There is nobody better and my whole neighborhood uses Plumbing Innovators.Posted on Google WTP familyTrustindex verifies that the original source of the review is Google. These guys are great! From the lovely lady who answers the phone to the two techs who came out. I am very pleased! They were reasonably priced, knowledgeable, thorough, and very clean. I highly recommend!!Posted on Google Nathan JohnsonTrustindex verifies that the original source of the review is Google. Came home from work to what I expected to be a Septic nightmare. I knew exactly who to call. Plumbing Innovators answered the call early in the morning and had a crew at my house super quick. The crew was amazing! Knowledgeable, professional, and honest. They had me all fixed up in less than an hour! Plumbing Innovators will always be my first and only call for any plumbing needs! They should be yours too!Posted on Google Jason BartlettTrustindex verifies that the original source of the review is Google. Once again, during a time of crisis when we had no water, Dillan, Melvin, and Thomas responded the same day. They quickly identified the issue and explained it thoroughly. They were extremely knowledgeable, professional, and trustworthy, and a pleasure to work with. Although parts were required, they graciously returned at 7:00 p.m. and worked in the cold to ensure our water was restored. This marks the third time in five years that we have used their services for unrelated issues, and each time they arrived the same day and resolved the problem. None of these were simple fixes. Thank you all for the outstanding service. We are customers for life.Posted on Google Dan MillerTrustindex verifies that the original source of the review is Google. I called about my leaky 75 gallon gas water heater the morning of New Years Eve. Carol was very pleasant to speak with. She scheduled me for that day, with the time that worked for me. The technicians Rikki and Clay removed the old one and replaced it (same size/brand, newer model) in just a few hours. Great guys - no salesman stuff. Quality workmanship. Great price. Thank you all.Posted on Google Joe RockTrustindex verifies that the original source of the review is Google. Called plumbing innovators late on 12/23/2025 about well pump. Thomas and Brandon showed up Christmas Eve and replaced pump in short order. Thomas and Brandon were pleasant and professional to deal with. I would recommend Plumbing Innovators to anyone needing plumbing work.Posted on Google Ethan SmithTrustindex verifies that the original source of the review is Google. Joe came out and walked me through my entire system as a new home owner. He was courteous and respectful. Really appreciate the service.

Questions

Tankless water heaters are more energy-efficient, save space, and provide hot water on demand. They are a great option for many homes and businesses, especially if you want better efficiency and do not want to run out of hot water.
This can happen because of mineral buildup, a clogged water filter, gas supply issues, an undersized unit, or winter groundwater temperatures. Our plumbers can diagnose the issue and recommend the right fix.
Most tankless water heaters should be serviced once a year. Annual flushing and inspection help remove mineral buildup, protect the heat exchanger, and keep the unit working efficiently.
