"Scott and Matt responded to my request immediately and came out to check our water heater. Scott offered all options and recommended the cheapest solution: flush our water heater. Then he showed me how to do it myself. He saved me money, and he taught me in the process. Wonderful men to work with. I will be recommending them to my friends, and will be using them in the future for my plumbing needs. Thanks!"

"EXCELLENT CUSTOMER SERVICE Eddie visited our house the very day we called about our water heater. He came out, inspected the very tough location where the water heater is located and delivered an estimate with 3 options on the spot. We decided which direction to go and let Eddie know at which time he promptly scheduled our installation. On the day of install he arrived when he said he would, put down every type of floor protection you can imagine and proceeded the very difficult task of manipulating a 50 gallon water heater out of a small closet 10 feet up in the air. He worked with his partner to remove the old one, replumbed and installed the new one, again in a very tight space. Eddie ran all new venting to the outside, added electronic monitoring, and crawled under the house several times to make certain the drains were all functioning properly. We could not ask for better service and the attention to detail was amazing. This is our second experience with Excalibur Plumbing and they have both been wonderful experiences. Great customer service!!!!"

"Fantastic. Everyone at Cold Is On The Right, from Kari in the office to Billy in the field, is terrific. Our job was complicated: remove two conventional hot water heaters, one of which was in the attic, and replace them with a tankless system. In addition, our house had two separate water loops, which need to be merged into one. Cold Is On The Right did everything on-time and on-budget. They're professional in every way. I recommend the company unreservedly and count myself a customer for life. Jeff Bowden, Austin."

"We recently had Colin install our new water heater, and the experience was truly excellent from start to finish. He was friendly and patient, taking the time to walk us through the process and explain the new unit. What stood out most was the detail-oriented nature of the work; everything was installed perfectly. When the job was complete, the work area was meticulously cleaned up. The new water heater is working perfectly, and we are very satisfied. We would absolutely call 1-800-Plumber+Air again for any future plumbing needs."

"Team Enoch did excellent work and service in replacing my water heater. Very quick in responding and provided same day service. Juan did an excellent job and was very complete and thorough with the installation. Did a wonderful job insulating the pipes, reconfiguring the pipes and putting in a drain pipe for the pan. After completion, he explained about the water heater, temperature settings and the pilot and answered all my questions. Great work and service!! Highly recommended!!"

Water Heaters FAQs, answered by experts

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

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.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.
