Water Heater Repairs and Replacements
At Linn-Benton Plumbing we also give our customers the best recommendation. For instance, typical life span of conventional tank type heater is 10-20 years in the Willamette Valley, depending on water quality and hot water useage. Replacement of your water heater may not be neccesary if your water heater is not leaking and still has a reasonable amount of service life left.

How Do Water Heaters Work?
Conventional water heaters have a storage tank that they use to store hot water. They tend to take a long time to heat the water and then have a large amount of hot water at your disposal. They use a glass lined steel tank that will eventually develop leaks and at that point need to be replaced.
Both electric and gas tank type water heaters have a diptube and an anode rod. The diptube is a tube that is installed on the cold inlet of your water heater and pushes all the cold water in the tank to the bottom. As water heats up, the hot water rises to the top of the tank and forms layers of hot and warm water with the hottest water being at the top of the tank. As you use up the hot water and the hot water is displaced by cold water, the dip tube minimizes the mixing effect of the cold water coming into the tank and allows the hot water to stay in layers maximizing the length of time the water stays hot.
The anode rod is a rod that is installed in your water heater tank and it typically has a steel core with an aluminum or magnesium coating. The pupose of the anode rod is to act as a sacraficial rod to protect the water heater tank. Minerals in your water corrode the anode rod before the steel tank, thereby protecting it from rusting, which results in a longer tank life.
Gas Water Heaters Serviceable Parts
Conventional gas water heaters have many serviceable parts including: gas valve, thermocouple or thermopile. The gas valve usually has a thermostat built into the valve that senses the water temperature in the tank. If the thermostat senses a low temperature, the gas valve will allow gas to flow to the burner until the thermostat senses that the water is hot enough, then the gas valve will shut off gas to the burner. The thermocouple or thermopile senses heat and will allow gas to flow to the pilot light as long as heat is prenent. This is a safety device to be sure no gas is flowing to the water heater if the pilot light goes out.
Conventional Water Heaters Serviceable Parts
Conventional electric water heaters have serviceable parts that include upper and lower elements and thermostats. The water heater elements are installed on the tank and are electric elements that come in contact with the water and heat the water. The upper and lower thermostats sense the water temperature and turn the elements on until proper temperature is reached and then shut off power to the elements.
