Residential water heaters are essential appliances that provide us with hot water for bathing, cooking, and cleaning. However, like any other household equipment, they are prone to breakdowns and malfunctions over time. Understanding why water heaters break down and learning how to maintain them can help extend their life span and save you from expensive repairs or replacements.

7 Reasons Water Heaters Break

Water heaters break down due to a variety of factors, including age and the malfunctioning of key components. Understanding these reasons is crucial for effective maintenance and prevention strategies.

  • Age: The most common reason for water heater failure is old age. Over time, the components wear out, and corrosion can occur, leading to leaks or inefficiency.
  • Sediment buildup: Sediments such as minerals, sand, and dirt can settle at the bottom of the tank, causing it to overheat and corrode.
  • High water pressure: Excessive water pressure puts a strain on the water heater’s internal components, leading to leaks or bursts.
  • Corrosion: Corrosion affects the tank’s lining and the heating elements, weakening them and causing leaks.
  • Faulty heating element or thermostat: A malfunctioning heating element or thermostat can prevent the water from reaching the desired temperature.

6 Tips To Prevent Water Heater Breakdowns

Preventing water heater malfunctions involves a combination of regular maintenance practices and simple adjustments to ensure optimal performance, energy efficiency, and an extended life span for the appliance.

  • Regular maintenance: Schedule regular maintenance with a professional to inspect and flush the tank, remove sediment buildup, and ensure all components are working correctly.
  • Check pressure valve: Test the pressure relief valve every six months to ensure it’s functioning properly. If it’s not working, it can lead to dangerous pressure buildup.
  • Adjust temperature: Set the water heater’s temperature to 120 degrees Fahrenheit to prevent overheating and reduce the risk of scalding accidents.
  • Use a water softener: If your area has hard water, consider using a water softener to reduce mineral deposits and extend the water heater’s lifespan.
  • Install an expansion tank: If you have a closed plumbing system, meaning water flows in through the supply line and can only flow back out through drains and sewer lines, installing an expansion tank can help absorb excess pressure and protect the water heater. Problems can occur because water expands when it heats up. If the plumbing system is full when expansion occurs, the water has nowhere to go unless it can flow into an expansion tank.
  • Insulate pipes: Insulate the hot water pipes to reduce heat loss and save energy, which can also decrease wear on the water heater.

When To Call a Plumber

Knowing when to call a plumber for your water heater is essential to avoid a worsening or even dangerous situation. Recognizing the signs of malfunction and understanding the threshold between manageable problems and professional intervention can help you maintain a functional and safe water heating system.

  • No hot water: If your water heater is not producing hot water or is producing inadequate amounts, it’s time to call a plumber to diagnose the issue.
  • Leaks: Any signs of leaks around the water heater should be addressed promptly, as they can cause significant water damage and lead to more severe issues.
  • Strange noises: Unusual noises, like popping or banging sounds, indicate sediment buildup or other internal problems that require attention.
  • Rotten egg or sulfur smell: An unpleasant odor may signal bacteria in the water tank or can be a sign of a corroded anode rod. Contact a Prime plumber to determine whether you need a new water heater or to flush and clean the tank and replace the rod if appropriate.
  • Rusty water: If your hot water appears rusty or discolored, there could be corrosion inside the tank, which should be addressed by a professional.

Emergency Situations

Certain signs accompanying water heater problems should raise red flags and prompt immediate action. Recognizing these emergency indicators is crucial for safeguarding your home, addressing potential hazards, and ensuring the timely assistance of a professional plumber:

  • Complete loss of hot water: A sudden, complete loss of hot water in the middle of winter or during essential activities constitutes an emergency.
  • Gas smells: If you smell gas around your water heater, turn off the gas supply immediately, leave the premises, and call for professional assistance.
  • Leaking water heater: A significant leak that cannot be contained with a bucket or a towel should be treated as an emergency.

Residential water heaters are vital appliances that require regular maintenance to prevent breakdowns and extend their life span. Understanding the common reasons for their failure, adopting preventive measures, and knowing when to call a plumber or handle emergencies can help ensure a continuous supply of hot water and keep your household running smoothly. Remember to consult with a professional plumbing contractor for any complex issues or doubts regarding your traditional or tankless water heater.

    [UPDATE: RESOLVED] I'm updating this review to reflect that Prime Plumbing has owned up to the situation and made it right. Once my new toilet arrived, they returned and completed the installation at no additional cost to me. The 5-stars are for Ernie and Hailey who handled the final install, and they were a complete 180 from my previous experience. They were awesome, professional, and sociable. You could tell they actually enjoy their work and take pride in it. They got the job done right. While the road to get here was frustrating, I appreciate the company standing by their work and sending the right team to finish the job. [OLD REVIEW] I hired Prime Plumbing to fix a toilet leak, and after 4 visits and hundreds of dollars, I had to do their work for them. Here is the timeline of negligence: March 27, 2025 (Invoice #90891): I paid an $89 trip fee to have a technician come out. He did a visual glance without even lifting the toilet and told me "nothing was wrong." The leak continued. Nov 1, 2025 (Invoice #97073): I paid $634.56 for a "Toilet Pull and Reset" (Service Code TUR-110). The invoice states they would "prepare the mounting system." They claimed the issue was a decayed wax seal (after initially guessing "condensation"). They did not inspect the toilet for cracks, but they didn't miss the opportunity to try and upsell me a new water heater. The leak continued. Nov 24, 2025 (Return Call): When they came back, the technician tried to blame "condensation" again and claimed "these electric toilets aren't reliable", again making excuses. He replaced the wax seal again without inspecting the toilet. Nov 30, 2025: The leak returned. Before booking them again, I spent 1.5 hours doing what they should've done. I replicated the leak and reached behind the toilet to feel the failure point. I felt the wax ring and—crucially—I felt plastic obstructing the seal. Dec 1, 2025 (Invoice #97936 Return Call): The tech arrived, and I told him what I found. He told me, "That's impossible... Show me how you did it. Show me this magic." I had to literally get on the floor and prove it to him. I ABSOLUTELY should not have had to do his job for him. He then complained about how he "can't keep coming out here" and is "losing money." Completely unprofessional. He finally pulls the toilet up, actually inspects it, and finds a crack. He sounded gleeful showing it to me, acting like this vindicated his misdiagnosis. He then told me I need to pay a third time to have a new toilet installed. THE REALITY: Did he inspect it the first time? If he did and saw no crack, then he caused the crack by mishandling the toilet. Did he not inspect it? Then the crack was there the whole time, and due to his incompetence, he misdiagnosed the issue for months while taking my money. I paid premium pricing for a professional diagnosis and fix. Instead, I got laziness in March, incompetence in November, disrespect in December, and an issue that wasn't fixed. Now they want more money to fix the issue they likely caused. Avoid this company unless you want to do the plumbing yourself after paying the bill. When my new toilet arrives, I will be reaching out to them to complete the install of the toilet at no additional cost to myself (I am not asking for a refund on the cost of a toilet, just want them to install it properly.) Otherwise, this is definitely going to be a complaint to the MHIC.

    Ernie and Hailey are absolute legends! I cannot say enough good things about Ernie and Hailey! I hired them to install a new toilet, and they turned what is usually a mundane maintenance appointment into a genuinely great experience. From the moment they arrived, the service was top-tier. They were incredibly professional and got the installation done flawlessly, but what really stood out was their attitude. They were sociable, friendly, and you could tell they actually have fun on the job. They have a great dynamic and brought such positive energy into my home while working. It is rare to find a team that combines expert workmanship with such a great "vibe." If you need plumbing work done and want it done right by good people, ask for Ernie and Hailey. 10/10 would recommend!
