Common Water Heater Problems
Water heaters can develop a range of issues over time, especially with regular daily use. If you’re experiencing any of the following problems, it’s time to call a professional before things get out of hand.
Ignoring any of these warning signs can lead to bigger, more expensive issues down the road. Our plumbers will thoroughly inspect your system, identify the root cause, and recommend the most effective repair or replacement solution.
No Hot Water or Fluctuating Temperatures
One of the most obvious signs of a problem is the lack of hot water or water that oscillates between cold and hot. This can be caused by several things, including a faulty thermostat, a broken heating element, or issues with the gas supply to the unit. In some cases, sediment buildup inside the tank can also interfere with effectively heating the water.
Sediment Buildup
San Antonio is notorious for having some of the hardest water in the United States, which comes primarily from the limestone-rich Edwards Aquifer. The high concentration of dissolvable minerals like magnesium and calcium causes buildup in your tank, which leads to a malfunctioning unit if it’s not regularly flushed and serviced.
Water Discoloration
Rusty or cloudy water coming from your faucet is a tell-tale sign of a problem, as it indicates likely corrosion inside your water heater or pipes. Most often, this is a sign that the anode rod, which helps prevent rust, needs to be replaced. Addressing this early can not only prevent future leaks from occurring but also extend the life of your water heater system.
Strange Noises
If your water heater is making banging, popping, or rumbling noises, it’s generally a sign of sediment buildup in the bottom of your tank. As water heats up, it pushes through hardened mineral deposits, resulting in unusual sounds. If left undiagnosed, this will not just reduce your system’s efficiency, but it will also damage your tank.
A Broken Thermostat
A broken water heater thermostat generally causes extremely hot water, no hot water, or inconsistent temperatures, which is often accompanied by a reset button that frequently trips. Common reasons for a broken thermostat include sediment buildup, wear and tear, or faulty electrical components.
Foul-Smelling Water
Water heaters that emit a foul, rotten egg smell are typically caused by sulfate-reducing bacteria that are thriving in the tank, creating hydrogen sulfide gas. This tends to happen most often when water sits in the tank for long periods of time or when the tank temperature is too low. Having your water heater tank professionally flushed, increasing the tank temperature, and/or replacing the anode rod are all common fixes.
Water Leaks Around The Unit
Any signs of water pooling around your water heater should be taken very seriously. Leaks can happen as a result of loose connections, a faulty pressure relief valve, or even cracks in the tank itself. And while some leaks are minor and easily repairable, others may suggest the need for a full water heater replacement. So, if you notice any leaks around your unit, call a plumber as soon as possible.
Low Water Pressure
If your hot water pressure has taken a nose dive, mineral buildup inside your tank or pipes could very well be restricting water flow. This is an especially common issue in San Antonio because of the prevalence of hard water. A professional plumbing inspection can effectively identify any blockages and restore the proper pressure.
A Spike In Energy Bills
If your power bills have started to increase without a clear explanation, your water heater could be the culprit. Aging parts, sediment buildup, or malfunctioning components can cause the unit to work harder than necessary, which results in using more energy to deliver the same amount of hot water.
Pilot Light Or Ignition Issues
For gas-powered water heaters, problems with the ignition system or pilot light can prevent them from heating water altogether. This can be caused by a faulty thermocouple, gas control valve issues, or a simple buildup of debris and dirt.
These elements require careful handling, so if you think you are having an issue with your pilot light or ignition system, always call a professional for an inspection rather than attempting to do it yourself.
Tank and Tankless Water Heater Repair
Eager Plumbing has over 30 years of combined experience servicing and repairing both traditional and tankless water heater systems in the Hill Country. That means that no matter which type of water heater repair you need, we’ll be able to help.
Traditional Tank Water Heaters
These types of water heaters store and heat water in a large tank. They also happen to be a common choice for many homes and businesses in San Antonio. Over time, worn-out heating elements, sediment buildup from hard water, or malfunctioning thermostats can diminish overall performance. We’ll restore your system’s efficiency and extend its life with the proper repairs.
Tankless Water Heater Repairs
Unlike their conventional counterparts, tankless water heater systems provide hot water on demand by heating water as it flows through the pipes. And while they do tend to be less “needy” than standard tank units, they do require some maintenance and occasional repairs to operate at their best. From hard water mineral buildup to ignition issues, our plumbers have the tools and know-how to handle any tankless water heater problem.

Water Heater Repair Or Replacement?
Not every water heater problem requires a full-on replacement. In many cases, a professional repair can restore your system’s performance for a fraction of the cost.
