"Jeremy was very responsive and informative. I had a couple of other quotes that involved various iterations of "replace the old water heater and add these other features at the same time", and we were able to talk through the suggestions and determine what was really necessary. The final quote was very competitive, the new water heater is working great, and the installation itself was fast and without any problems that they couldn't solve without me!"

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"My husband is ill and I needed help. My water heater wasn't working so I called High Speed Plumbing. Donald was wonderful ! He arrived earlier than expected and was very personable. He found the problem quickly and replaced the water heater and some electrical problems. I had smelled plastic burning so I was very concerned. I now have hot water and am not concerned about a fire hazard. I would recommend this company and will call Donald the next time I have an issue. Great experience !!"

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.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.
