Apex homes are some of the newest in the Triangle, so many water heaters are original units now hitting the age when elements, igniters, anode rods and valves start to fail. Those parts are usually repairable; a leaking tank isn't. Call the number on this page to be connected with a local plumber in Apex.
What Apex homeowners should know
The Town of Apex runs its own water system, with water from Jordan Lake treated at the Cary/Apex plant. Its 2024 report describes the water as moderately soft, about 1.9 grains per gallon, and lists chloramine as the disinfectant (running average 3.23 ppm), with a switch to chlorine each spring from late February into early April. Soft water keeps scale modest, but sediment still collects, and chloramine can wear rubber gaskets and valve seats over time.
Housing is very new: the median Apex home was built in 2008 and fewer than 4% predate 1980. That means a lot of garage and attic tanks from the same building wave, many now 12 to 18 years old. Natural gas, where available, comes from Enbridge Gas North Carolina (formerly PSNC). For a gas smell, leave and call 911 or Enbridge from outside.
One Apex rule stands out: the town requires a permit even for a like-for-like water heater replacement, and the work must be done by a contractor holding a state license. That doesn't affect repairs, but it matters if the plumber finds the tank is done.
Common failures and what they mean
| What you notice | Likely part | Typical outcome |
|---|---|---|
| No hot water, electric unit | Element or thermostat | Repair |
| Gas burner won't light | Igniter, flame sensor or thermocouple | Repair |
| Drip at the bottom valve | Drain valve or washer | Repair |
| Water seeping from the tank seam | Tank failure | Replace (permit required in Apex) |
Because so many Apex heaters went in during the same years, neighbors often see the same failures within a short span. If a nearby house just lost its heater, yours may be close behind, and checking the anode rod and drain valve now can extend the tank's life.
Signs it's time to call
- Hot water lasting noticeably less time
- Water in the drain pan under an attic heater
- Error codes or flashing lights on a newer gas unit
- A sulfur smell from hot taps
Seasonal notes
The spring chlorine switchover sometimes brings a slight change in taste or smell; it isn't a heater problem. Cold winter inflow is what usually exposes a weak element or igniter, so if your heater has been slow to recover, fall is a good time to have it checked before the holidays bring a full house.
