"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."

"Giovanni was very professional, arrived on time, and kept in contact by phone and message about arrivals, needed equipment, and expected work. He was careful to explain what needed to be done and why and approached work with a positive attitude. The job involved replacing some valves on an exterior faucet set on copper pipes. Afterward, he noticed that the house water pressure was high and found that the regulator was not working so I had him replace that. Overall this was a very positive experience and I would say he is one of the good guys. Give him a call if you need some plumbing work done."

"Lonnie is an awesome plumber! When I first got my house he installed new water valves for my washer. Just recently he came to repair my water heater because it was leaking. He noticed I still had warranty on my water heater. Any other plumber probably would have charged me for a new one. I really appreciate his honesty. I would definitely recommend his services"

"Alex with 805 Plumbing was quick to respond to our request for help with our septic system. He offered options for us to deal with the problem, and allowed me to watch as he diagnosed our situation with the use of a camera. I never felt pressure to take a path that would be more expensive, and every step of the way I was kept informed of what he had discovered. I am confident that our problems were efficiently taken care of, and although I would not wish septic problems on anyone I would recommend Alex and 805 Plumbing to anyone who is in need of plumbing services. Alex is a reliable, fairly priced, professional, and experienced plumber, and I will use him again in the future."

Water Heaters questions, answered by experts

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.

You should replace your gas water heater when it’s reached the end of its lifespan, which is a maximum of 12 years in most cases. If your unit is over a decade old and showing signs of inefficiency, leaks, or frequent malfunctions, it may be time to replace your water heater. Research how to best maintain your gas water heater to help extend its lifespan.

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.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.
