"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

Water Heaters questions, 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.

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.

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.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

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.
