Water Heaters FAQs, answered by experts

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

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.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

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.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
