A leaking water heater can cause significant water damage to your home if not addressed promptly. Whether it's a small drip or a major leak, dealing with a leaking water heater requires immediate action to prevent further damage to your floors, walls, and belongings. Here's a step-by-step guide for homeowners in Marietta, GA on what to do when your water heater leaks, including how to shut off the water supply, minimize damage, and when to call professionals for help.

Step 1: Shut Off the Water Supply

The first and most important step in dealing with a leaking water heater is to shut off the water supply to prevent more water from leaking into your home. Most water heaters have a dedicated shut-off valve located near the top of the unit where the cold water enters.

How to Shut Off the Water Supply:

  • Locate the Shut-Off Valve: Look for the cold water supply pipe leading to the top of the water heater. There should be a valve on this pipe—either a gate valve (wheel handle) or a ball valve (lever handle).
  • Turn the Valve Off: If it’s a gate valve, turn it clockwise until it is fully closed. If it’s a ball valve, turn the lever 90 degrees so that it is perpendicular to the pipe.
  • Check for Water Flow: Once the valve is closed, check if the water flow has stopped. If water is still leaking, you may need to shut off the main water supply to your home.

Main Water Supply Shut-Off (If Needed):

  • Locate the Main Water Shut-Off: The main water shut-off valve is typically located near the water meter, either inside or outside your home. It’s usually found in basements, utility rooms, or on the exterior walls.
  • Turn Off the Main Water Supply: Turn the main shut-off valve clockwise (if it’s a gate valve) or turn the lever 90 degrees (if it’s a ball valve) to stop the water flow to your entire home.

Step 2: Shut Off the Power Supply

Once the water supply is turned off, it’s important to shut off the power to the water heater to prevent electrical hazards, especially if you have an electric water heater. Even gas-powered water heaters should be turned off to avoid further damage.



How to Shut Off the Power Supply:

  • Electric Water Heater: Go to your electrical panel and locate the circuit breaker that controls the water heater. Flip the switch to the "off" position to cut off the power supply to the unit.
  • Gas Water Heater: For gas water heaters, locate the gas shut-off valve near the bottom of the heater. Turn the valve to the “off” position to stop the flow of gas to the unit.

Step 3: Drain the Water Heater (If Necessary)

If your water heater is leaking heavily, you may need to drain the tank to remove the remaining water and prevent further damage (Need flood water cleanup in Marietta, GA?). Draining the water heater can also help relieve pressure and reduce the amount of water leaking from the tank

  • Attach a Hose to the Drain Valve: Locate the drain valve at the bottom of the water heater. Attach a garden hose to the valve and place the other end of the hose in a floor drain, sink, or outside.
  • Open the Drain Valve: Turn the drain valve counterclockwise to open it and allow the water to flow out of the tank. Be cautious, as the water may still be hot.
  • Open a Hot Water Faucet: To help the water drain faster, open a hot water faucet in your home. This will allow air to enter the tank and speed up the draining process.

Step 4: Contain the Water and Prevent Further Damage

While dealing with a leaking water heater, it's important to contain the water and prevent further damage to your floors, walls, and belongings. Use towels, buckets, or mops to absorb or divert water away from sensitive areas.

Containing the Leak:

  • Use Towels and Buckets: Place towels or rags around the base of the water heater to soak up any standing water. Use buckets to catch any dripping water if the leak is coming from the top or sides of the heater.
  • Protect Nearby Items: Move any belongings, furniture, or electronics away from the water heater to prevent water damage. If the water has spread to other areas, take steps to protect your flooring, walls, and other surfaces.
  • Use a Wet/Dry Vacuum: If there is significant water on the floor, use a wet/dry vacuum to remove the water and prevent it from soaking into carpets or flooring.

Step 5: Inspect the Water Heater for the Source of the Leak

Once the immediate risks are under control, inspect the water heater to identify the source of the leak. Are you covered for water damage mitigation?. This will help determine the next steps for repair or replacement

Common Causes of Water Heater Leaks:

  • Loose Pipe Connections: Check the inlet and outlet connections where water enters and exits the water heater. Loose or corroded connections can cause leaks. Tighten or replace any damaged fittings.
  • Temperature and Pressure Relief Valve (T&P Valve): The T&P valve releases water when the tank’s pressure gets too high. If the valve is faulty or the pressure is too high, it may be leaking. This can be a sign of a more serious issue with the heater.
  • Leaking Drain Valve: The drain valve at the bottom of the heater may not be fully closed or could be faulty. Tighten the valve or replace it if necessary.
  • Corrosion in the Tank: If the water heater is old and has developed corrosion inside the tank, it may be leaking from the bottom. Unfortunately, this often means the tank has reached the end of its life and will need to be replaced.

Step 6: Contact a Professional Water Damage Mitigation Service

After you’ve taken the initial steps to shut off the water supply and contain the leak, it’s important to contact a professional water damage mitigation service. They can assess the extent of the water damage, ensure the affected areas are properly dried, and recommend repairs or replacements for the water heater if necessary.

Why You Should Call a Professional:

  • Thorough Water Removal: Professionals use advanced equipment, such as wet vacuums, air movers, and dehumidifiers, to ensure that all water is removed from your home and prevent further damage.
  • Prevent Mold Growth: If water has seeped into walls, floors, or other areas, mold can begin to grow within 24 to 48 hours. Professional water damage mitigation services will ensure that all moisture is removed to prevent mold and mildew from developing.
  • Water Heater Repair or Replacement: A professional plumber can inspect the water heater to determine if it can be repaired or if it needs to be replaced. In cases of significant damage or an aging unit, a replacement may be the best option.

Preventing Future Water Heater Leaks

Taking steps to maintain your water heater can help prevent future leaks and extend the life of your unit.

Water Heater Maintenance Tips:

  • Inspect Regularly: Check your water heater for signs of rust, corrosion, or leaks at least once a year. Pay attention to the connections, T&P valve, and drain valve for any signs of wear or damage.
  • Flush the Tank Annually: Sediment buildup in the water heater tank can cause corrosion and lead to leaks. Flushing the tank once a year helps remove this sediment and keeps the heater running efficiently.
  • Replace the Anode Rod: The anode rod helps prevent corrosion in the water heater by attracting corrosive elements. Replacing the anode rod every 3-5 years can help extend the life of your water heater and prevent leaks.
  • Monitor Water Pressure: High water pressure can put stress on your water heater and lead to leaks. Install a pressure regulator if your home’s water pressure exceeds 80 psi to protect the heater from excessive pressure.
