Westinghouse storage-tank water heaters are common in households that want straightforward hot water at predictable cost, but tank units carry leak risk that should strongly influence repair decisions. Energy.gov notes storage water heaters typically last about 10-15 years, so this dataset uses the conservative midpoint of 12.5 years.
Repairs under the threshold are often worthwhile for replaceable parts like anode rods, thermostats, heating elements, and T&P valves when the tank itself is not leaking and the unit is under mid-life. Replacement is usually the safer choice if the heater is older and shows rust-colored water, moisture at the base, or significant sediment rumbling, because tank corrosion can lead to sudden failure and water damage.
If the unit is located in a finished area or attic, the risk cost of a leak should tilt decisions toward replacement even sooner. The replacement price benchmark reflects a common mid-market 50-gallon tank heater listing at a major home-improvement retailer; total installed costs vary based on code upgrades, venting, and disposal.
