Common warning signs include inconsistent hot water, strange noises coming from the tank, rusty or discolored water, water that smells metallic, reduced water pressure, or visible leaks around the unit. If you notice any of these issues, a technician can diagnose the problem early and prevent bigger damage.

Repairs are usually recommended for small issues like faulty valves, heating element problems, or minor leaks. Replacement is the better choice if the water heater is over 10–12 years old, has major tank corrosion, or continues breaking down. We provide honest recommendations based on your system’s age, efficiency, and long-term cost savings.

Most traditional tank water heaters last 8–12 years, depending on maintenance, water quality, and usage. Tankless water heaters can last 20+ years with proper care. Regular flushing and tune-ups can significantly extend your unit’s lifespan.

This may happen due to a failing heating element, sediment buildup inside the tank, thermostat issues, or an undersized water heater. We diagnose the exact cause and restore proper heating performance quickly.

Leaks typically occur from loose connections, failing valves, corroded tanks, high water pressure, or worn-out seals. Early detection is important because even small leaks can lead to major water damage or mold growth.

Yes. Direct Service Plumbing specializes in tankless water heater installation, including Navien, Rinnai, and other high-efficiency brands. Tankless systems provide endless hot water, lower energy bills, and longer lifespan compared to traditional units.

Most standard tank installations take 2–3 hours, while tankless systems typically take 4–6 hours depending on venting, gas lines, and electrical requirements. We complete all work safely and up to local Charlotte code.

This is usually caused by sediment buildup at the bottom of the tank. As sediment hardens, it creates pockets of trapped water that boil and pop. Flushing the water heater fixes the issue and helps the unit heat more efficiently.

Yes. We repair, service, and install electric, gas, hybrid, and tankless water heaters. Our licensed plumbers can handle everything from thermostat issues to gas line adjustments and full-system replacements.
