Water Heater Services

Our team handles a full range of water heater services to make sure you always have dependable access to hot water. We work with both tank and tankless systems, delivering honest recommendations and quality workmanship on every job.

Water Heater Installation

If you’re building a new home or replacing an outdated system, we’ll help you choose the right water heater for your needs and budget. Our team installs both traditional tank models and modern tankless systems, each with benefits based on your usage and household size. We’ll walk you through options for energy efficiency, size, and fuel type so you get a system that fits your lifestyle. Every installation is done to code with long-term performance in mind.

Water Heater Repairs

Noticing inconsistent temperatures or strange noises coming from your water heater? Our licensed plumbers can troubleshoot the issue and provide fast, targeted repairs. We carry the tools and replacement parts to handle many common problems on the spot. You’ll get clear communication about what’s going wrong and how we can fix it, without upsells or pressure.

Tankless Water Heaters

Looking to upgrade to a more efficient and space-saving model? Tankless water heaters deliver hot water on demand, reducing energy waste and creating more storage space. We specialize in tankless system installation, repair, and maintenance for Rock Hill homes. Our team will explain how tankless units work and help you determine if they’re a good fit for your household’s needs.

Routine Maintenance

Regular maintenance extends the life of your water heater and improves efficiency. Our tune-up service includes flushing sediment buildup, checking the anode rod, inspecting the thermostat, and verifying safety features. Maintenance not only prevents future issues—it also helps lower energy bills and reduces the chances of a full breakdown. It’s a smart investment in your home’s daily comfort.

Common Issues We See in Water Heaters

Water heaters often give off early signs when something isn’t working properly, and catching these signs early can save you from a bigger repair bill later on. At Full Spectrum Plumbing, we routinely diagnose a wide range of problems that affect hot water performance and safety. Many of these issues can be repaired quickly, but in some cases, replacement may be the smarter long-term solution. Our team is trained to evaluate your system honestly and recommend the most cost-effective fix. Below are some of the most common issues we see during service calls:

  • Lukewarm or No Hot Water: A faulty thermostat, broken heating element, or sediment buildup may be to blame. We inspect and test components to get to the root of the problem quickly.
  • Rusty or Discolored Water: Corrosion inside the tank or deteriorating anode rods can lead to brown or orange-tinted water. Replacing the anode rod or flushing the tank can often solve this issue.
  • Unusual Noises: Popping, banging, or rumbling sounds usually indicate sediment buildup at the bottom of the tank. Flushing and cleaning can restore quiet operation and improve efficiency.
  • Leaks Around the Base: Water pooling under the tank could point to a cracked tank or a failed temperature and pressure relief valve. We act fast to assess and repair the leak before it causes property damage.
  • Inconsistent Water Pressure: A clogged pipe, failing expansion tank, or mineral deposits could be disrupting your water flow. We’ll check all connections and components to restore balanced pressure.
