A Coventry CT homeowner called us because her hot water heater was leaking. Because a leaking water heater can burst at any moment, a plumber technician was scheduled for the same day. The electric heater was completely rusted out on the bottom. To avoid further water damage in the home, our technician replaced it during the service call. It's extremely important to have your water heater serviced every 3-4 years. It will preserve the warranty on your heater, which can save you money if it fails prematurely. If you need to call a Coventry CT plumber for service, it's helpful to know if you have a gas, oil, or electric unit. It's also helpful to know the age of the equipment. The typical lifespan of a water heater is 8-10 years, depending on how often it's serviced and the quality of your water.
