Water Heaters questions, answered by experts

While many older homes don’t need hot water heater expansion tanks, they’re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don’t require expansion tanks.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

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.

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.
