We are problem solvers, installers, designers, leak stoppers, clog killers, pipers, and safety experts. We do a lot of things, really. We have been in the Dallas area for more than 60 years, and have sent our expert technicians throughout the Dallas metro area to tackle jobs big and small.

"Koen Plumbing was very responsible, professional, respectful, honest, and do quality work. They replaced the first plumber I hired for this job as the first plumber was a terrible . The difference between was night and day. Koen plumbing returned calls, showed up on time, did quality work and then followed up. I would highly recommend"

"Tyler Perry at Reliant Plumbing – My Aqua Man Hero! I had never heard of Reliant Plumbing before my search, but their 24/7 availability and same-day service promise caught my attention—and wow, did they deliver! From the moment Tyler Perry arrived, I knew I was in good hands. Water line repairs can be overwhelming, but Tyler’s approach was nothing short of exceptional. He took his time to thoroughly explain all three repair options, ensuring I understood every detail. His patience and clarity turned a stressful situation into an informed decision, and he was incredibly mindful of the financial impact, presenting payment options that truly eased my anxiety. Beyond his technical skills, Tyler showed a level of care and professionalism that’s rare. He was prompt, courteous, and even returned later to complete a complimentary service to help resolve my ongoing water leak dilemma. His commitment to going the extra mile speaks volumes about both his character and Reliant Plumbing’s integrity. And as a self-made handylady, I loved that he let me tinker around in the mud and the hole to learn more about the process firsthand! Not many pros would welcome that, but Tyler embraced it, making the entire experience feel collaborative rather than just another service call. If you’re looking for a plumber who combines expertise, compassion, and top-tier service, look no further. Tyler Perry at Reliant Plumbing is the real deal—my Aqua Man hero!"
