What To Do Right Now

Turn Off Power/Gas

For electric heaters, switch off the breaker. For gas heaters, turn the gas valve to OFF position. This prevents fire hazards and further damage.

Shut Off Water Supply

Turn off the cold water inlet valve on top of the water heater. If you can't find it or it's stuck, shut off the main water supply.

Drain the Tank (If Safe)

If the tank is leaking badly, attach a hose to the drain valve and run it to a floor drain or outside. Open the valve to reduce flooding.

Check for Gas Smell

If you smell gas (rotten egg odor), leave immediately, don't operate any switches, and call your gas company from outside the home.

Document the Problem

Note the water heater's age, model number, and take photos of any damage. This helps the plumber prepare the right parts.

Frequently Asked Questions

Should I repair or replace my water heater?

Generally, if your water heater is over 10-12 years old and needs major repairs, replacement is more cost-effective. Minor repairs like replacing a heating element or thermostat are worthwhile on newer units. Your plumber can assess the condition and advise.

How long do water heaters last?

Traditional tank water heaters last 8-12 years with proper maintenance. Tankless water heaters can last 15-20 years. Regular flushing and anode rod replacement can extend lifespan significantly.

Is a leaking water heater dangerous?

Yes, a leaking water heater poses several risks: water damage to your home, potential for scalding from hot water, electrical hazards, and for gas units, possible gas leaks. Don't ignore even small leaks.

Why is my water heater making banging noises?

Banging or popping sounds usually indicate sediment buildup at the bottom of the tank. As water heats, steam bubbles form under the sediment and cause the noise. Flushing the tank can help, but excessive buildup may require professional cleaning or replacement.

Can I install a water heater myself?

While homeowners can technically install water heaters, it's not recommended. Installation involves gas or electrical connections, water lines, venting, and code compliance. Improper installation can void warranties, cause safety hazards, and violate building codes. Professional installation is strongly advised.
