"I had Micah of Fox Plumbing replace my old water heater. He is friendly, knowledgeable and professional. After running into several issues; shoddy workmanship previously performed, trying to get the right size for my small opening, and the fact that it took two days to drain due to a lot of sediment present, he patiently worked through everything, by himself, to set up my water heater correctly with new connections as well. He also provided a drip pan, which surprisingly there wasn't one there before. I highly recommend him for your plumbing work. He's a super nice guy. I will be referring him to my sister for a new water heater."

Water Heaters FAQs, answered by experts

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

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.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.
