"I had a 20+ year old water heater. The expansion tank developed a leak. I contacted Wagner and Sons. Mike gave me a suggestion to temporarily fix the leak. After discussion I contracted him and his son to replace the water heater and expansion tank. He said he could be there at 12:00PM on Monday. He was right on time. He replaced the water heater and the expansion tank in just over one hour. Hauled away the old heater for free."

"My 15 year old water heater started leaking and causing my carbon monoxide detector to go off. I decided to just get a new one since it was on its last legs anyway. The first plumbing service I called couldn't fit me in until the following afternoon, so I called Plumb-It instead. Scott quoted me some prices and said he could be there the same afternoon, and in fact, he arrived a little early, which was great. Everything took about 2 hours, the new water heater has been great, and my CO detector has been silent. Definitely would hire again."

"I called Top Tec Oct 4 to check my existing water heater. Steve came out and looked it over and gave me the bad news. My 9 year old water heater was shot. The next day, Steve removed my old water heater and installed a new Rheem water heater. I could not be more pleased with how quickly the work was completed and with Steve’s expertise!"

Water Heaters questions, answered by experts

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

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.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

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.
