What to Do When Your Water Heater Starts Leaking in Rock Hill or Fort Mill

A leaking water heater is more than just an inconvenience—it can turn into a major plumbing emergency if not handled quickly. Whether you’re in Rock Hill, Fort Mill, or anywhere nearby, knowing how to respond when your water heater starts leaking can save you from costly repairs and water damage.

TLDR: Don’t Ignore Water Heater Leaks

If your water heater is leaking, shut off the power and water supply, then call a professional immediately. Even a small leak can escalate fast. HOTCO Carolinas offers emergency water heater repair in Rock Hill and Fort Mill and is available 24/7 to respond to leaks and minimize damage.

Step 1: Identify Where the Leak Is Coming From

Before you panic, take a moment to inspect your water heater and try to locate the source of the leak:

  • Top of the tank – This could indicate loose connections or faulty valves.
  • Bottom of the tank – Often a sign of internal tank failure, which usually means replacement.
  • Pipes or fittings – These may just need tightening or resealing.
  • Drain valve or T&P valve – These are common culprits and may be repairable.

A professional plumber can pinpoint the source accurately and tell you what needs to be done.

Step 2: Shut Off Power and Water Supply

Safety is your top priority. Here’s how to prevent further damage:

  • Electric water heaters – Turn off the power at the circuit breaker.
  • Gas water heaters – Turn the gas control valve to the “off” position.
  • Water supply – Locate the cold water shut-off valve above the heater and turn it off.

Once you’ve done this, place a towel or bucket under the leak and avoid using hot water.

Step 3: Don’t Delay—Call a Professional

Leaks don’t fix themselves, and waiting can lead to:

  • Mold or mildew buildup
  • Floor and wall damage
  • Corrosion and permanent appliance damage
  • Complete water heater failure

Our team at HOTCO Carolinas responds quickly to water heater leaks in Rock Hill, Fort Mill, and the surrounding areas. We’ll assess whether the unit can be repaired or needs to be replaced, and we’ll explain your options clearly.

Common Causes of Water Heater Leaks

Here’s what might be causing the leak:

  • Old age – If the unit is 10+ years old, the tank may be deteriorating.
  • Sediment buildup – This can lead to cracks and corrosion over time.
  • High pressure – Without an expansion tank, excess pressure can cause leaks.
  • Faulty valves – T&P or drain valves often wear out and start dripping.
  • Poor installation – Improper fittings and bad soldering can create issues.

Knowing the cause helps determine if repair is possible or if replacement is necessary.

Is Repair or Replacement Better?

  • Repair is possible if the leak is coming from a valve or fitting.
  • Replacement is likely if the leak is from the tank itself, especially in older units.

Our technicians will give you an honest recommendation and never upsell unnecessary work. You’ll know exactly what you’re dealing with.

How to Prevent Future Leaks

Once the issue is fixed, take a few proactive steps to protect your investment:

  • Install a drain pan – This catches small leaks before they cause damage.
  • Add an expansion tank – Prevents pressure from stressing your system.
  • Flush the tank regularly – Reduces sediment buildup.
  • Schedule yearly maintenance – Catch minor issues before they become leaks.

HOTCO Carolinas offers water heater upgrades and add-ons that help extend your system’s life.
