"After looking at what was suppose to be done, and the entire job was evaluated, I was told I would be better off in getting a complete new water heater, and not put new parts in an 8 year old water heater, for once I felt like I was not ripped off, and given the best advice, and that is what I will do."

"I called yesterday, our hot water heater was not working. The service was exceptional - from looking at our old unit. Offering to make temp repairs and recommended the best options. To having a new one installed with some reconnection repairs, totally professional and one of the best customer service experiences I have ever had! If you need anything their services supply, call them- you will not be disappointed. Pricing was also very reasonable and will definitely call them again! Thanks to both the gentleman that supplied service to us!"

Water Heaters questions, answered by experts

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.
