We are committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"McDaniel Plumbing has been my plumbing contractor for many years. He replaced my 20-year-old garbage disposal this time. He has saved the day more than once. When I was hurt and needed a handheld shower so I could sit in a shower chair, he came to my house the day I got out of the hospital to make sure it was ready. He also quickly solved my rental’s very bad basement leakage problem before it did any more damage. Not only is he competent and a perfectionist, he also goes above and beyond by explaining things to me so that I can prevent future problems. For example, there is an old tree near my water main shutoff and he suggested I contact the water company to get water line Insurance coverage, that it was inexpensive and important in my case. I did that and now have peace of mind. As a widow, it’s so important to have these bits of information that I would never know. I count on McDaniel Plumbing because I know the work will be done right and the price will be fair."

Tankless water heater installations FAQs

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.
