"Long Holiday Weekend and my hot water heater quit. We had just moved in too. That should have been caught in inspection. Oh well. By chance we had HVAC repair scheduled and they offered to look at the water heater, but My Guy already squeezed us into his schedule. I'm so glad he did. His price came in lower than the HVAC service person's quote. My Guy provided options for repair vs replacement. Knowledge is power, and I feel we were given all the information up front. We opted to replace. He showed us how to operate the water heater and told us the schedule for maintenance to get the longest use of our new water heater. I highly recommend My Guy. We'll have him back again when we replace the sink and dishwasher."

"I had both of my toilets backed up and reached out on Angis and Straight Shooter was the first to respond to my inquiry. They were able to send a technician out the same day and were able to fix my back up issue. I didn't realize my toilets were like 30 years old so they quoted me for replacements and when we decide to do that work we will call them again."

Water Heaters FAQs, 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.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

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.

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.

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.
