The short answer
That popping is your tank cooking itself. Sediment has built up on the bottom of the tank, and water trapped under it is boiling. A yearly flush helps. Ignore it long enough and heavy buildup shortens the life of your water heater, and you end up paying for a new one sooner than you had to.
Why Tulsa tanks pop
Tulsa water is hard. According to the City of Tulsa, water from the A.B. Jewell treatment plant averages 8.2 grains per gallon and water from the Mohawk plant averages 5.2 grains per gallon. Those minerals settle in the bottom of your tank every single day. That layer is what you hear popping.
What to do about it
- Flush the tank every year. That is what we suggest for every tank water heater in Tulsa. We put a yearly reminder in our system for you.
- Change the anode rod every two to three years. It helps protect the tank.
- Tankless owners: Navien units need a yearly service, and without a whole-house filtration system you should flush them every year to keep scale from building up.
When popping means it is time to replace
A flush will not save every tank. Stop and call us if you see any of these:
- Red water or flakes coming out of the hot side.
- Heavy rust around the top fittings where the flex connectors attach, or inside the combustion chamber.
- Water leaking from the tank itself. A tank split inside cannot be repaired.
- The tank is 10 to 15 years old and needs a major repair.
Plan on replacing a tank water heater around 10 to 15 years. If you are replacing, it is worth hearing about tankless too.
