Frequently Asked Questions About Water Heater Repair
Should I repair or replace my water heater?
Repair usually makes sense for a tank under about 8 years old with a single failed part, such as a heating element, thermostat or valve. Replacement is the better call when the tank itself leaks, the unit is 10 to 12 years old or older, or repairs keep repeating. Santos Mechanical handles both.
How long does a water heater usually last?
A tank water heater typically lasts 8 to 12 years, and a tankless unit often lasts 20 years with regular care. Hard water, sediment buildup and skipped maintenance shorten that life. Flushing the tank and checking the anode rod and pressure relief valve during routine maintenance helps a tank reach the long end of the range.
Why does my water heater run out of hot water quickly?
Fast run-out usually comes from sediment filling the bottom of the tank, a failed lower heating element on an electric unit, a broken dip tube, or a thermostat set too low. A tank that is simply too small for the household causes it too. A diagnostic visit pinpoints which one before any parts are replaced.
Can a leaking water heater be repaired?
It depends on where the leak starts. Leaks from the pressure relief valve, drain valve or pipe connections can usually be repaired. A leak from the tank itself, often seen as water pooling under the unit, means the tank has corroded and needs replacement. Shut off the water supply and the power or gas, then call.
Can I replace a tank water heater with a tankless model?
Yes, most homes can switch from a tank to a tankless water heater. The switch may need venting changes, enough fuel or electrical capacity, and a unit sized for your household's peak hot water demand. Santos Mechanical installs tankless water heaters and will check your home's setup during a free estimate.
