"We have had several services completed by NE Plumbing. They have serviced our swamp cooler in the spring & fall for 2 years, & done a great job. Last December, our water heater was leaking, and Pepe and his team stayed until 9pm that night to complete the work. Based on their suggestion, we replaced it with a tankless water heater & we are extremely happy with it. It has reduced our power consumption while giving us hot water efficiently when we need it. Pepe has gone above & beyond what was expected to give us excellent customer service. Prompt, knowledgable, thorough, & friendly. Highly recommend!"

"The company appears to have finally fixed our repeated leaks by turning down the water pressure as Sonic Leak Detection suggested, and making other important adjustments to our leak detection hookup."

"They had great communication with me and were very polite. They even gave me the cell number of the estimator to work out the details of a modified cost estimate. They were extremely fast and efficient in getting out to the Futura House and getting me a cost estimate as well as replacing the hot water heater. If you want work done fast and complete, this is the company you want to use."

Water Heaters questions, answered by experts

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

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.

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.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

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.
