"Kyle and Justin installed a new 75 gallon water heater in my home this past week. The job was extensive due to need to remove incorrect pvc piping then install proper grade pvc to meet code. In addition they replaced and re install rigid piping for gas lines that apparently builder had not done correctly (shorts cuts!) this was also verified by another plumbing contractor of which we brought in for an estimate. So glad we went with Water Mac to do the job. Kyle and Justin's work was outstanding! These guys are nice, honest ,competent and fairly priced. I highly recommend them. Tammy Schoffelen"

"Called Home Depot at 6:03pm on Saturday 2/26/22. At 6:30pm Arctic Air Conditioning contacted me, had me take photos of my broken hot water heater. 15 minutes later, Katie from Arctic called me back with a more than fair price and worked her magic to get me an install for Sunday 2/27/22 at 2pm. Alex from Arctic arrived Sunday around 2pm and started the project. Elijah from Arctic arrived 45 minutes later and by 6pm ( 24 hours after my initial call) we had a new hot water heater up and running. Great experience, Alex and Elijah were professional, knowledgeable and courteous."

"Excellent customer service. My Hot water heater busted on Christmas night and i called advanced professional 26th early morning, tech at my home in no time to provide estimate and work was done within next 4-6 hours. Technician name Abe who came to my house for service is one of the best. Very polite, professional and make sure work is done neat and clean. Only one thing i am not happy is i think it was little pricey but since it was urgent service i can't complain."

Water Heaters questions, answered by experts

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.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.
