Water Heater Repair

If the tank body is leaking rather than a fitting, close its cold inlet valve and shut off the power or gas to it, because that failure only goes one direction.

When this becomes an emergency

What a pro does

The plumber decides repair or replace early, and says which plainly. A failed element, a bad thermostat, a leaking connection or a spent anode rod are all repairs. Rust weeping through the shell of the tank is the end of it. Coastal South Carolina is hard on this appliance for a reason people underestimate: salt carried inland on the sea breeze attacks exposed metal, and a heater in an open garage or under a raised house in a place like Georgetown or Beaufort corrodes at the fittings long before an identical tank inland would. Inland the issue is different, more about sediment and about water that's soft enough to eat the anode rod quickly. So the service is a sequence. Drain and flush the sediment out of the bottom. Pull the anode rod and see what's left. Test the relief valve. Check whether the expansion tank on a closed system still has air in it. Then look hard at the fittings, the flex connectors and the shutoff, because on the coast those are frequently in worse shape than the tank itself.

Frequently asked questions

In a garage or an open under house space, yes. Sea air moves inland on the breeze and settles on everything, and metal fittings that stay damp in humid conditions corrode faster with salt on them. It shows up first on copper connectors, valve bodies and the sheet metal jacket rather than on the tank lining.
It is a sacrificial metal rod inside the tank that corrodes instead of the steel. When it is consumed, the tank itself becomes the target, and the heater enters its last stretch. Very few homeowners have ever had one inspected, and doing it is the cheapest thing that extends a tank's life.
It usually comes from a reaction between the anode rod and sulfur bacteria in the water, which is more common on wells than on treated town supply. Changing the rod material often addresses it, and a plumber can advise based on what your water actually contains.
Not always. Sediment reduces the usable volume in a tank, a lower element failing on an electric unit produces exactly this symptom, and sometimes the household simply outgrew the tank it has. The plumber checks the appliance before recommending a bigger one.
