With years of experience in the plumbing industry, we are the experts you need to take care of your home. We handle all of your plumbing needs with great care. We will treat your home as we would treat our own. Give Fast Drains Plumbing a call today, we look forward to working with you!

"When our pilot light went out Friday evening, a major plumbing company quoted $800 to replace the gas valve assembly—or $4,000 for a full replacement. That felt excessive, so I started calling around. Enter Adam Burton of Fast Drains Plumbing. From our first conversation, I felt at ease. He’s a master plumber with years of experience, and his pricing was refreshingly fair. We booked him, and he showed up on a Sunday to replace both our water heater and water pressure regulator, which were well past their prime. Adam was fast, efficient, and incredibly thorough. He had us back up with hot water in under two hours. Genuine and professional, he delivered top-tier work. I wouldn’t hesitate to recommend Fast Drains Plumbing to anyone dealing with an aging water heater."

"They told us "Our dispatch fee to come out is $39 and we waive that towards any work or repairs, including diagnostics." The electrician went to check and stayed at the property for less than 5 mins after confirmation to do full diagnostic of the electrical system. I don't think less than 5 mins is enough to run a full diagnostic and later on advise to upgrade the whole panel."

FAQs for tankless water heater installation projects in Dunwoody, GA

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.
