Often, problems with electric water heaters come from faulty heating elements. Your water heater will come with two elements — one located up high, and another down toward the bottom of your water heater.
Temperature-Pressure Relief Valve The TPR lets water escape if the temperature or pressure is too high in the tank. This component is a safety measure that keeps your tank from blowing up. It should be mounted on the top of the tank or on the side of the tank, within 6 inches from the top.
The T&P valve, or temperature and pressure relief valve, is one of the most important safety devices in your home. If the temperature rises above 210 degrees Fahrenheit or the pressure exceeds 150 psi, the valve will open and relieve the pressure inside the tank.
Water leaks are perhaps the most common type of water heater issue you'll face. Any water heater will start to leak eventually, as by nature water will eventually corrode your tank and create microscopic cracks or fractures.
A water heater element can cost between $10 and $60 and can be found at most home improvement stores. If you're comfortable with light electrical work, replacing a water heating element is a DIY task.
The longevity of water heaters without anode rods is about: 5-8 years. The actual lifespan depends on water hardness, water heater type and quality, when the anode rod was removed, and how hot the water is. In extreme cases, the water heater may only last 3-5 years without an anode rod.
How Long Do Water Heaters Last. — The majority of water heaters last between eight and ten years. While ten is the age at which heater replacement is generally recommended, the actual need to replace a heater could arise before or after this timeline.
Upper and lower heating elements are identical, and the temperature is regulated by the upper and lower thermostat and high limit device. Electric water heater elements can be different in size, but the most common is 12" (300 mm).
Temperature and Pressure (T&P) Relief Valves.
The purpose of the temperature pressure relief valve is to release water, and in turn lower the pressure inside the tank, in the event that the temperature or pressure gets too high in your water heater.
