Layman Plumbing LLC was created in 2023. William Layman is the owner and operating responsible master plumber. William grew up in Plano, TX, and graduated from Collin College. After getting a college degree, he still didn't know what he really wanted to do. He couldn't find a decent paying job with his new degree, so he decided to just keep working at his job in retail. He eventually realized that retail just didn't make him happy. A good friend, who was a plumber, recommended trying a trade. So he tried plumbing, and he liked it! He liked working with his hands, and he always took pleasure in helping people. After a decade in the plumbing industry, building his knowledge and experience, he finally became a master plumber and started his own plumbing company in the same area where he grew up, Collin County. Finally, he knew what he was meant to do. He was meant to be a part of something bigger. His goal now is to provide outstanding plumbing service to the same community that he grew up in. To serve his family, friends, neighbors, and community. Mission Statement To provide plumbing service with the highest standards for all your plumbing needs. Plumbing that you trust. Plumbing Made Simple. We do hydrostatic testing, Plumbing, Water Leak Detection and Repair, Slab Leak Detection and Repair, Sewer Repair, Camera Inspection, Tankless Water Heaters, Gas Leak Detection and Repair, plumbing remodel, and more.

"William was quick to respond, effortless scheduling to get assistance in helping with a water leak in my yard. William was on time and a pleasure to work with. I highly recommend Layman plumbing for timeliness workmanship and identifying the problem quickly. Cost was very reasonable as well. Don’t hesitate to give layman plumbing a call for your next plumbing need."

FAQs for tankless water heater installation projects in Allen, TX

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
