Sometimes, a repair is just not cost-effective
When a water heater leaks, that’s one of the surest signs that it needs to be replaced. There are some instances where repairs can be made, but in other cases a repair will not be cost-effective. Here are some of the main reasons why water heater leaks take place.
The drain valve, which allows you to empty the tank for cleaning, may become loose and let water escape. This valve can usually be easily tightened with a wrench.
Another typical cause is a buildup of excess pressure in the tank, which causes the temperature pressure release valve to open and lead to a leak. This valve, for example, will commonly trip if the temperature of the appliance is set too high. This problem can also be caused if the pressure of the water coming into your home is too high, or if the release valve is faulty.
Corrosion and rust are two of the most common reasons for tank leaks. If this is occurring in your unit, you’ll probably need to have it replaced. Tanks can last up to 20 years in some cases, but as they age they build up sediment. As this occurs, corrosion can eat through the tank.
