"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"I would absolutely use Jax Mechanical in the future. Justin and Zac were very professional and thorough. I was very hesitant, due to a previous bad encounter with Service Master. Justin and Zac were patient and not condescending. Michael was quick with the bid/estimate and I am grateful for their service. If you need a water heater installed, be assured that Jax Mechanical is the only call you need to make."

"Arturo and James was great. AMC plumbing that asked for pictures and didn't try to charge us to troubleshoot. We eventually settled on changing the water heater but we were informed at every step what is happening. Thanks for being to take all our questions and told us how to take care of the new water heater. Excellent!"

"I contacted Anderson Plumbing Heating & Air, a honest and trustworthy company after I realized at the last minute I needed a refrigerator water line assessment and they quickly sent Miguel to my home who noticed upon assessment inspection the water pressure was unsatisfactory and recommended replacing the water pressure valve in addition to the refrigerator water line. Miguel was absolutely amazing , a breath of fresh air, very easy to work with, and managed to accommodate my water line hookup needs fitting me into his busy schedule. Miguel provided me with a great service experience at very reasonable price! He went above and beyond providing before and after pictures of my old and new water setup, answers all of my questions, all while providing outstanding customer service with a smile & 10/10 quality of work! Thank you Miguel for a great refrigerator water line hook up experience !!"

Water Heaters FAQs, answered by experts

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

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.

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.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.
