"My water heater had gone out and called and called around trying to get quotes and big company’s were trying to schedule in person quotes which I know is a strong arm to get the work done then and there because they are already at your house ect. But with Behold I had a personal direct text from them asking about my situation and all I had to do was give some info send in pictures and voilà! They gave me their quote(2300$) which also beat all the company’s(3k$+) I had heard from! They had a tech out to me ASAP. It almost could’ve been same day but I was in no rush.

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

Water Heaters questions, answered by experts

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.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

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.

Price variations arise from size, type (tankless or tank), efficiency grades, and installation complexity, including labor and materials.

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.
