A reliable water heater is something most homeowners don’t think about until it stops doing its job. Whether you have a traditional tank system or a tankless unit, water heater problems often worsen over time. Recognizing early warning signs can help you avoid cold showers, water damage, and more expensive repairs. At River City Heating & Air, we provide expert water heater repair and replacement in the greater Bismarck area. Here’s a look at five common signs of water heater trouble. Unusual Noises Coming from the Tank If you hear popping, rumbling, or banging sounds coming from your water heater, it’s often a sign that sediment has built up inside the tank. Over time, minerals settle and harden on the bottom, trapping water beneath the sediment. As the water bubbles up, it creates loud noises. This noise is your early warning—don’t ignore it. Fluctuating or Insufficient Hot Water One of the most obvious signs of a problem is inconsistent water temperature. If your water suddenly goes cold, doesn’t get as hot as it used to, or fluctuates during use, it could indicate a failing heating element or a malfunctioning thermostat. Tankless systems may show similar symptoms if the burner is failing. Any change in performance is worth investigating before the issue becomes more severe. Discolored or Rusty Water If you turn on the hot water tap and notice the water looks brown, orange, or rusty, your water heater may be corroding from the inside. This commonly means the anode rod has worn out and can no longer protect the tank from rust. Left unchecked, corrosion can eat through the metal and lead to leaks or complete tank failure. Leaks Around the Water Heater Even minor pooling around your water heater should never be ignored. Leaks can come from loose connections, a failing valve, or cracks in the tank. Once a tank begins to crack, replacement is usually necessary. Water leaks can quickly cause structural damage and mold growth, so prompt action is crucial. Age and Slow Performance Decline Conventional water heaters commonly last between eight and twelve years. As they age, they naturally become less efficient and more prone to problems. If your system is approaching or past this range and you notice slower heating, unusual behavior, or rising energy costs, it may be nearing the end of its useful life. Replacing it before it completely fails could save you money in the long run.
