When the shower runs cold on a January morning in Lansing, the first question is usually "Can this be fixed, or do I need a new water heater?" The answer depends on the age of the unit, what is actually failing, and how much you want to spend on a tank that may be near the end of its life anyway. This guide walks through the same questions our plumbers ask when we look at a water heater, so you can make a clear decision instead of a rushed one.
How Old Is Your Water Heater?
Age is the single biggest factor. Most standard tank water heaters last roughly 8 to 12 years. Hard water, which is common across Greater Lansing, can shorten that by building up sediment in the bottom of the tank. You can usually find the manufacture date on the label on the side of the unit, often coded into the serial number. If your heater is past the 10-year mark and starting to have problems, replacement is often the smarter long-term choice, because a repair today may be followed by another failure next season.
Problems That Are Usually Worth Repairing
Many water heater issues are straightforward and affordable to fix, especially on a unit that is still fairly young:
- No hot water on a gas unit: often a pilot, thermocouple or gas control issue.
- No hot water on an electric unit: frequently a failed heating element or thermostat.
- Water that is only lukewarm: can be a broken dip tube, a bad element, or a thermostat setting.
- A dripping temperature and pressure (T&P) relief valve: the valve may need replacement, or pressure in the system may need attention.
- Rumbling or popping noises: usually sediment buildup that a flush may improve.
If the tank itself is sound and the heater is under about eight years old, repairing one of these parts is usually the economical route.
Signs It Is Time to Replace
Some symptoms point to the end of a tank's life. These are the ones we take most seriously:
- Water pooling around the base of the tank, or rust-colored water from the hot side only. A leaking tank cannot be patched.
- Visible corrosion on the tank, fittings or the bottom of the unit.
- Repeated repairs in the last year or two.
- Hot water that runs out much faster than it used to, even after flushing.
- A household that has grown, so the tank no longer keeps up.
A leaking tank is the clearest signal. Water damage to a finished basement can cost far more than the heater itself, so if you see water on the floor, shut off the water supply to the heater and call a plumber.
Tank vs. Tankless for Michigan Homes
If you are replacing, it is a good time to consider whether a tankless (on-demand) water heater fits your home. Tankless units heat water only when you need it, take up much less space, and can last longer than a standard tank. Michigan's cold incoming groundwater means a tankless unit has to work harder in winter, so proper sizing matters. Gas line size and venting also need to be checked. A traditional tank is simpler and usually less expensive to install. A plumber can look at your hot water use, your gas or electric service, and your space to tell you which makes sense.
Hard Water and Your Water Heater
Hard water leaves mineral scale inside tanks and tankless heat exchangers. That scale makes the heater work harder and can shorten its life. If you see white crust on faucets or spots on dishes, a water softener or treatment system can protect a new water heater and your other fixtures. Annual flushing also helps.
Simple Maintenance That Extends Life
- Flush the tank once a year to remove sediment.
- Test the T&P relief valve periodically.
- Keep the area around the heater clear for airflow and safety.
- Have the anode rod checked every few years; it protects the tank from corrosion.
When to Call a Plumber
Gas appliances, electrical connections and pressure valves are not DIY projects for most homeowners. If you smell gas, see water around the tank, or have no hot water, call a licensed plumber.

Frequently Asked Questions
How long does a water heater last in Michigan?
Most tank water heaters last about 8 to 12 years. Hard water and lack of flushing can shorten that.
Is it worth repairing a 10-year-old water heater?
Usually only for a small, inexpensive part. If the tank leaks or has repeated problems, replacement is typically the better value.
Is a tankless water heater good for Michigan winters?
It can be, if it is sized for cold incoming water and your gas line and venting are adequate. A plumber should check before you buy.
What should I do if my water heater is leaking?
Shut off the cold water supply to the heater, turn off power or gas to the unit, and call a plumber.
