Reliable hot water is a requirement for any functional Georgia household, especially when dealing with the high humidity and varying seasonal temperatures of the Southeast. Since 1968, R.S. Andrews has served as the first point of contact for homeowners from Marietta to Decatur when plumbing systems fail. 

The Metro Atlanta water supply often carries specific mineral profiles and red clay sediment that settles at the base of your tank. This accumulation leads to premature heating element burnout and restricted flow. We understand the specific plumbing codes of Fulton, DeKalb, and Gwinnett counties to ensure your system remains safe and compliant with local regulations.

 

System Failure Symptoms to Watch For

Identifying a failing water heater early can prevent water damage and high utility bills in your home. If you notice any of these symptoms, your system likely requires a professional inspection:

  • Fluctuating Water Temperatures: You experience sudden bursts of cold water during standard usage.
  • Discolored Water: Rusty or brownish water flows from your hot water taps.
  • Storage Tank Noises: Unusual popping or rumbling sounds come from the tank during a heating cycle.
  • Standing Water: You see visible moisture or pooling around the base of the unit.
  • Limited Capacity: Your hot water volume runs out significantly faster than usual.
  • Foul Odors: Persistent metallic or sulfur smells in the water.
  • Unit Age: Your system is exceeding ten to twelve years of service.

Diagnostic and Repair Process

Our technicians diagnose the mechanical failures common to Georgia homes, such as corroded dip tubes and failing thermocouple sensors. In many Metro Atlanta neighborhoods, high water pressure from municipal lines can stress your thermal expansion tank. This often leads to leaks at the pressure relief valve.

We recalibrate your burner assembly or replace electric heating elements that have been encrusted with calcium. If your pilot light won’t stay lit or you only receive lukewarm water, our team arrives with the specialized diagnostic tools to find the gas-flow bottleneck immediately. We stock common parts on our service vehicles to complete most repairs in a single visit to minimize downtime for your household.

Preventive Maintenance Benefits

Regular maintenance is the most effective way to extend the lifespan of your water heater and protect your investment. We provide flushing services to remove the heavy mineral deposits that settle at the bottom of the tank and reduce heating efficiency.

Our plumbers also inspect the sacrificial anode rod. This component is designed to attract corrosive elements and protect the internal tank lining from rust. By scheduling annual maintenance through the Smiley Advantage Plan, you can avoid the sudden need for water heater repair Atlanta homeowners often face during peak demand periods. This proactive approach identifies minor hairline cracks or valve leaks before they become catastrophic floods in your basement or utility closet.

We also offer water filtration services that can help reduce the amount of minerals passing through your home plumbing system. This places less burden on your water heater and can help prolong its functionality. 

System Replacement and Selection

If your current unit is beyond repair or has become inefficient, we provide water heater installation Atlanta services for all major brands. We help you choose between traditional storage tanks and modern tankless water heaters based on your household’s specific water usage and peak demand.

Our team handles the entire replacement process, including the removal of the old unit and ensuring all new gas or electric connections meet Metro Atlanta plumbing regulations. We calibrate the thermostat and test the temperature and pressure relief valves to confirm the new system operates at maximum efficiency. This ensures your new unit provides a consistent supply of hot water while keeping your monthly energy costs as low as possible.

Hot Water Convenience System Installation

Improve comfort and convenience in your home or workplace with modern hot water solutions. We install hot water recirculation pumps that deliver hot water faster to every tap, reducing wait times and preventing water waste, which is an ideal upgrade for larger homes or busy households. 

For added kitchen convenience, we also install compact instant hot water dispensers that provide near-boiling water on demand for drinks and quick meals. Each system is installed with reliable components, proper filtration where needed, and built-in safety features to ensure efficient and dependable performance.

Tankless Water Heater Services 

Beyond traditional tank systems found in many homes across Metro Atlanta, our team also provides repairs, installations, maintenance and replacements for tankless water heater systems. Depending on your home’s plumbing system and your water usage habits, upgrading to a tankless water heater may be the right solution. 

These may be reasons to decide to upgrade to a tankless water heater: 

  • High Hot Water Usage: Tankless systems heat water on demand, making them a great option for homes where multiple showers, appliances, or fixtures may run at the same time.
  • Need To Improve Energy Efficiency:  Because they only heat water when it’s needed, tankless units can help reduce energy consumption compared to traditional storage tanks.
  • Need More Space: Tankless systems are compact and wall-mounted, making them ideal for utility rooms, basements, or tighter installation areas.
  • Long-Term Upgrade: Tankless systems often last longer than traditional tank water heaters and can provide reliable performance for many years with proper maintenance.
  • More Consistent Hot Water: With the right system size and professional installation, tankless units can provide a steady supply of hot water without waiting for a tank to refill.

Call R.S. Andrews today to ask about a tankless hot water heater. We will guide you through the process, selecting the best model for your home, and provide you with a transparent estimate to help you decide if it is right for you.

April 21, 2026: Well, R.S. Andrews came to my rescue again. This time I needed the water supply lines to 2 of my toilets replaced as per my homeowners insurance company. Loren, the RS Andrews plumber, was able to replace both lines with only a slight hiccup in one of the lines. He did an excellent job and detailed everything in my receipt so that I could forward my receipt to the insurance company. Loren was awesome. Thank you RS Andrews for saving the day….again. February 2026: Will Macon was totally awesome! I’m a caregiver for my 89 year old mother who just came out of the hospital on Sunday. Our furnace went out on Tuesday. I called R. S. Andrews on Tuesday. Will was at our home on Wednesday morning. He examined our system and got us a GREAT DEAL on a new furnace and AC. It was awesome. The new system was installed on Thursday. By Thursday afternoon we had heat from a NEW FURNACE. Thank you Will and thank you R. S. Andrews for all that you do. You may have saved a life. Thank you!!!! Alane L. Sullivan

After having a couple other companies look at our plumbing and tell us they "couldn't" fix our problem (we have a mixture of stainless steel & cooper pipes; virtually unheard of for residential!), we tried R.S. Andrews. Their attitude from the start was "How can we help" and they found a solution! Not only did they solve that problem, but we've used them for all plumbing and HVAC needs since because the folks provide great service at a fair price!

All the Techs that R S Andrews has sent were very courteous and professional. All details for the repairs were explained along with any follow up visits. Any costs were explained before the Techs came out. I would recommend R S Andrews to anyone who needs home repair.

Brian Turner, technician, and his assistant did an excellent job of diagnosing a gas leak at my water heater and redesigning a more efficient setup and replacing the water heater. It was a huge all day job and they worked tirelessly to make sure things were improved and safe. He was excellent at explaining every step and the reason for the changes. He also repaired other small issues in tub and outdoor faucets.
