My water heater stopped making hot water. What usually causes it?+
On electric tank units it is often a failed heating element or thermostat. On gas units, a pilot or thermocouple problem is common. On tankless units, scale buildup or a flow or ignition fault is the usual cause. A professional can test the unit and confirm which part has failed before anything is replaced.
What does a tankless water heater error code mean?+
Error codes point to the system that needs attention — ignition, flame, exhaust, water flow or overheating, depending on the brand and code. Write the code down before you reset the unit, and tell the professional the code and the model when you call. That helps them arrive with the right parts and checks in mind.
How often should a tankless water heater be flushed in South Carolina?+
Most manufacturers recommend a flush about once a year. Parts of South Carolina have mineral content that builds scale inside the heat exchanger faster, and scale is one of the most common causes of tankless shutdowns and temperature swings here. If your unit has never been flushed, mention that when you call.
Should I repair or replace my water heater?+
Age is the biggest factor. A tank unit around 8 to 12 years old with a major failure is often near the end of its life, while a younger unit with a failed element, valve or sensor is usually worth repairing. A leaking tank itself cannot be repaired — the unit has to be replaced. A professional can check the age, condition and failed part and lay out both options.
Can a leaking water heater be repaired?+
It depends where the water is coming from. Leaks from a valve, fitting or drain line can often be repaired. Water coming from the tank body itself means the tank has corroded through and the unit needs replacement. Turn the water supply to the unit off and describe where you see water when you call.
Is gas water heater repair different from electric?+
Yes. Gas units involve the burner, gas valve, pilot or ignition system and venting, while electric units involve heating elements, thermostats and breakers. The diagnosis steps and safety checks are different, so tell the professional which type you have — it is printed on the label on the unit.
Can I ask about the cost of the work when I call?+
Yes. When you call, you can describe the problem and discuss the visit and what an estimate for the work would involve with the professional. Ask them to put the agreed scope and warranty terms in writing before work begins.
What should I do before the professional arrives?+
Clear a path to the water heater, note the brand, model and age from the label if you can read it safely, and know where your main water shutoff is. If the unit is leaking, turn off the water supply to the unit. If you smell gas, leave the house first and call your gas utility or emergency services.
