First, locate the leak's origin
A water heater leak is rarely a simple issue. It's a sign of a deeper problem. Knowing exactly where the water is coming from helps determine if you need a minor part, a repair for a connection, or a complete tank replacement. Use a dry cloth to check four key areas around the unit: the cold water inlet, the hot water outlet, the TPR valve's drain line, and the tank's bottom.
Leaks from the top connections
If water is dripping from the cold inlet, hot outlet, or anywhere along the supply lines, the problem is likely with a fitting, a flexible connector, or a shutoff valve. This is usually a repairable issue, often costing less than $200 in most Columbus homes. Older homes in German Village or Clintonville sometimes have galvanized supply lines that corrode at the threads. Replacing the union often resolves this.
Leak from the TPR drain line
If the TPR (temperature and pressure relief) valve is dripping, it means the unit is either under too much pressure or the water inside is too hot. In some Columbus neighborhoods, especially those connected to the Dublin Road plant, city water pressure can sometimes exceed 80 PSI, which can cause the TPR to activate. A pressure regulator on the main line, along with a properly sized expansion tank, can help. If the TPR continues to weep afterward, the valve itself has failed and requires replacement.
Leak from the tank's base
This is typically the most serious problem. Water pooling at the bottom of the tank indicates that the tank itself has corroded and failed. There is no practical repair for this. The unit must be replaced. If your water heater is 8 years old or more, this is a common failure mode in Columbus, where moderately hard water (around 7-8 grains) can eventually compromise the anode rod and then the tank wall itself.
